everdrive for SNES!

[KRIKzz]

just want notice that now i have a lot of time for my SNES flashcart project. all functions already works and projet is very close to finish!

my handmade proto PCB:

Thats awesome! :love2:

I am just wondering what the USB port is for? Also, any chance it can support DSP games? (Either through physically adding the DSP chip, or through hardware emulation)

I hope there is another group buy when its finished...

<EDIT> Is it also going to be called EverDrive? Or will the final revision be called something different, like EverSNES, EverSuper, or EverSystem etc?

[KRIKzz]

usb port it is optional feature. SD and USB can be used for game upload, i use usb for debug and for fast OS upload (directly from PC, immediately after code compilation), so i just can press "build" in my IDE, and result will be shown on console (:

DSP/superfx not supported. may be later i will made some additional t-connector for DSP donors attach

[indask8]

This is really great.

I'll certainly buy one as soon as available, especially if we can add Super FX or any other special chip in the future.

That sounds really useful, especially for developers :nod:

From your pictures it looks like there might be enough space on the left hand side of your cartridge to leave a space/socket to solder in a DSP-1 chip? You would not have to install a DSP-1 yourself, but maybe just leave a space on the PCB for users to install if they wish? (At least until a T-connector is available)

...It would be good if you could hardware emulate a DSP-1 chip though ;-)


This is really great.

I'll certainly buy one as soon as available, especially if we can add Super FX or any other special chip in the future.
I dont think it will ever be possible to support Super FX with a T-connector, because on Super FX games the ROM is accessed through the Super FX chip itself, and the ROM input pins are not available on the cartridge edge connector:-
http://www.snescentral.com/pcb.php?id=0674&num=0&side=front
The only 'easy' way to support Super FX would be through hardware emulation of the Super FX chip itself, or by desoldering a Super FX chip and making a 'Super FX Only' flash cartridge.

You can support DSP chips through a T-connector though. The DSP-1 is the most commonly used DSP chip:-

Awesome work KRIKzz, can't wait unti it's out so I can pick one up :)

[KRIKzz]

Thats awesome! :love2:

it will be called everdrive, may be super everdrive

[APE]

Put me down for one of these for sure.

[nesworld]

Oh I'd be interested in one for these for sure :-)

[mdmx]

it will be called everdrive, may be super everdrive

why don't you call it SuperDrive ;-)

[causticsoda]

great work Krikzz!, next up Everdrive64? :D

[sheath]

I will definitely be buying one of these as well. Between the Genesis one and this you're about to save me a fortune in games I don't want but need access to for comparison purposes.

Any chance of a HuCard version in the future?

[gazcbm]

As a proud owner of an EverDriveMD, I will definatley be ordering one of these. Price point?

[KRIKzz]

Any chance of a HuCard version in the future?
what is the "HuCard" ?


As a proud owner of an EverDriveMD, I will definatley be ordering one of these. Price point?
will be available in end of next month, price 75usd aprox


great work Krikzz!, next up Everdrive64? :D
still not decide who will be next

[n64coder]

still not decide who will be next

My vote is for N64 version.

[sheath]

what is the "HuCard" ?

PC-Engine or TurboGrafx-16 games.

[KRIKzz]

PC-Engine or TurboGrafx-16 games.

currently i even have not TurboGrafx-16

[link83]

What about an Everdrive for the original Game Boy/Pocket/Color using microSD? There are flashcarts for the original Game Boy, but none that can hold more than a couple of games.

[alphagamer]

How about an Everdrive for the NeoGeo? :thumbsup:

[KRIKzz]

everdrive for GB has a good chance to birth next.
NeoGeo is very rare system, so currently i have not plans about neogeo and other systems who sold in less quantity then 10-20 million of copys in worldwide.
from other side neogeo has my loved m68k cpu, so software making for neogeo will be just like pleasant relaxation , so...
anyway i should buy neogeo somewhere for first (:

Well then you gotta decide MVS or AES. :)

Not cheap even in my neck of the woods, hate to see what the Ukraine locals ask for it.

impossible to find some stuff like this in Ukraine. most of my cosele bought on ebay

[raylyd]

put me down for one and the n64 cart aswell

[MottZilla]

I'd really like to see Everdrive for the GameBoy/GameBoy Color. That would be sweet.

PC-Engine/TG16 and N64 are nice ideas too.

[rso]

Another potential buyer for a GBC Everdrive here.

Also, I'd love to see one for the Game Gear! Tototek's is way too big, yours wouldn't even need to be cheaper, just being a smaller size would be great...

[sheath]

currently i even have not TurboGrafx-16

Sure thing, I appreciate whatever I can get. I don't even know how a HuCard version would work since I've never seen one opened in the first place.

[MottZilla]

HuCard wouldn't need a case to be put into it. See Tototek's PC-Engine flash card.

[Treamcaster]

Holy jizz, I guess I'm up to it as well, I got a SFC and I need more games :D
What a smart dude we have around!


P.S. What if we arranged various types of group purchases, for instance:

1-For those who want to buy SFCeverdrive only.
2-For those who still didn't buy GENSeverdrive only.
3-For those who want to buy both a.k.a better discount applied.

You can support DSP chips through a T-connector though. The DSP-1 is the most commonly used DSP chip:-
http://en.wikipedia.org/wiki/List_of_Super_NES_enhancement_chips#DSP

The retrousb SNES CF flash cart comes with a DSP-1 chip on its board, enabling games like Super Mario Kart. He could go the other way and include the SA-1, which is used by games like Super Mario RPG. Theirs also uses CF cards, which I believe load much faster than SD.

[KRIKzz]

retrousb SNES cart has big FPGA chip and DSP implemented inside of this FPGA. also retrousb use ram for game hold, i use flash in my carts. flash mutch more slow for write than ram, but games will stay in memory after power off. CF ussage have not sense if cart based on flash.

Not really, because the SA-1 is like the Super FX in that the ROM is accessed through the SA-1 chip:-
http://www.snescentral.com/pcb.php?id=0049&num=0&side=front
If KRIKzz made an SA-1 flash cart he would have to include an SA-1 chip on every cart, and that would be quite costly and destructive to buy hundreds/thousands of SA-1 games just for the SA-1 chip. Not only that but it would then be an 'SA-1 Only' flash cart and could not be used for other games.

Actually I am positive the DSP-1 chip is not implimented inside FPGA on SNES PowerPak, because originally you had to choose to buy a cartridge with or without the DSP-1 chip installed at the retrousb store checkout, and it used to cost extra to have one fitted.

Here is the SNES PowerPak release thread at nesdev:-
http://www.nesdev.com/bbs/viewtopic.php?t=5708
Notice some of the following posts by "bunnyboy" the creator of SNES PowerPak:-

Optional DSP1 chip for Mario Kart.

interesting, are any additional enhancement chips like the super fx chip for example planned and are they possible to implement?
Since there is no mention of it and the real DSP1 is installed manually I assume not, but I thought i would ask.

Enhancement chips are simply not happening. DSP/C4 can probably be quickly done with a PIC, but by the time you make the Super FX you are a significant way to doing the entire system. For the small number of games and the big increase in hardware it was a design decision early on not to do them.

Also on page 2:-

PS. About DSP1 support, I have a donor cart but there arent any instructions on how to install it. I'm guessing that theres a socket on the pcb it'l solder straight into and does it get completely disabled for non DSP games?

Desolder from game board, solder onto SNES PowerPak board, done http://www.nesdev.com/bbs/images/smiles/icon_smile.gif

I suggested adding a space for the DSP-1 on the Everdrive PCB because from what I understand it should not affect any other games when its installed. The ROM is not accessed through the DSP-1:-
http://www.snescentral.com/pcb.php?id=0166&num=1&side=front

More DSP-1 info here:-
http://users.tpg.com.au/advlink/dsp/dsp1.html

So if you have a space on the PCB users can optionally install a DSP-1, but if there is no space/traces thats not really an option. The only problem is I think the DSP-1 requires SRAM, and I am guessing the Everdrive will use FRAM? It was just an idea, and I thought if its easy to do it would be good to have DSP-1 support as an option (Although maybe KRIKzz might want to consider making a DSP-1 PIC? ;-))

I hope all that made sense!

well, main problem about flash is not the spped at all
flash memory has a limited number of write cycles, so sooner or latter those flash based carts will start giving problems

I really think that ram is much better than flash for such project

Whilst some sort of RAM would be nice, you have to take component costs into consideration - RAM is much more expensive than flash. In addition the chip KRIKzz uses has 100,000 program/erase cycles per block - I really cant see myself ever using anywhere near that many writes/erases.

In other words I could flash the Everdrive five times a day, every day, for almost 55 years before the flash chip would wear out.

Also, once the game is loaded into flash it can be accessed instantly as many times as you like, with RAM you have to load the game every time you play (Although the loading would be quicker) Lastly, even if the flash chip did wear out (unlikely) its not impossible to replace it with a new one if you have the right equipment/skills. Overall, to make a flash cart like this for a fair price I think flash is the right choice :nod:

...Now if the games were larger (e.g. N64) I would be tempted to use some sort of RAM to avoid the long loading times...

This would be on an ideal world
i got pendrives that died after 2 years of use
Sorry, but its impossible to avoid bad blocks on flash devices, i hope bad sector handling has been implemented on those devices.

Anyways, i have to say that even not having an original everdrive, i love the whole thingle.

[WaverBoy]

Would the SNES Everdrive be compatible with any games that RetroUSB's SNES PowerPak isn't? Or vice versa?

[alphagamer]

Someone on the German electronic hobbyists forum http://www.mikrocontroller.net/forum/

had a test routine running for quite some time, basically doing this:

1) Programming a flash chip to the max capacity
2) Reading the program and verifying if there were any write errors
3) Repeat

He stopped it after around 500,000 cycles with no errors.

Flash chips are more durable than you think.

[MottZilla]

Also remember, the NOR type flash used in a cartridge like this is generally built to a higher standard than NAND type flash in USB Memory Sticks, SD Cards, and CF Cards. NOR Flash is alot more expensive than NAND, but you couldn't make a flash cart like this with NAND. Atleast I'm pretty sure you couldn't.

[KRIKzz]

Not really, because the SA-1 is like the Super FX in

ah you rihgt. i even don't know why i thought that retrousb imlement dsp on fpga. shame :redface:

unfortunatly PCB's for my snes flashcart already odered on factory, so i can't add holes for DSP


Would the SNES Everdrive be compatible with any games that RetroUSB's SNES PowerPak isn't? Or vice versa?
compatibility will be same like in RetroUSB, except DSP1 games. SNES PowerPak damd good (:

[Alchy]

Just wondering how many revisions of the SNES/SFC you've tested with, because the PowerPak has pretty bad compatibility. I'm on my third SFC and still no luck.

Bad compatibility? I've got your basic original large model SNES and was thinking of getting the PowerPak for it; won't it work?

[nesworld]

I'm so down for an Everdrive64 too :-)

[link83]

Bad compatibility? I've got your basic original large model SNES and was thinking of getting the PowerPak for it; won't it work?
Originally the SNES PowerPak had poor compatibility and didnt work with a number of SNES motherboard revisions, apparently this is was all fixed with later firmware updates though. Someone asked about the reasons for the problems here:-
http://www.nesdev.com/bbs/viewtopic.php?t=5708&postdays=0&postorder=asc&start=330&sid=5cc05cd9a2bc667e3419a717c5d143de

I cant find the posts now that mention this specifically, but from reading the thread I got the impression the main problem was due to different brands of RAM being used on different SNES revisions, which caused timing issues (Like the problems with the original Xbox 1.6 to 1.6b motherboard revisions)

<EDIT> Seems like SNES PowerPak still has some issues according to this thread:-
http://www.nintendoage.com/forum/messageview.cfm?StartRow=26&catid=22&threadid=32536<EDIT>

From pictures I have seen online I made this list of SNES motherboard revisions:-
NTSC
SHVC-CPU-01
SNS-CPU-GPM-01
SNS-CPU-GPM-02
SNS-CPU-RGB-01
SNS-CPU-RGB-02
SNS-CPU-1CHIP-01
SNN-CPU-01 (SNES Jr)

PAL
SNSP-CPU-01
SNSP-CPU-02
SNSP-CPU-1CHIP-01
SNSP-CPU-1CHIP-02

I dont think its really feasible to run tests on every motherboard revision? Maybe just try testing on an early/first and later/last revision if possible.

[MottZilla]

You never know, Everdrive for SNES may turn out to have no compatibility issues.

KRIKzz, how much Flash ROM does SNES Everdrive have? What is the largest game you can play?

[KRIKzz]

8mbyte total memory, 4mbye max rom size, 32kbyte max save size

[mdmx]

unfortunatly PCB's for my snes flashcart already odered on factory, so i can't add holes for DSP

Do you have plans for a new pcb revision in the future which has a socket for the DSP chip?



8mbyte total memory, 4mbye max rom size, 32kbyte max save size

so the hacked Star Ocean won't work because it needs 12mbyte, am I right?

Some games like Donkey Kong Country have an SRAM check, used to detect backup units which have more sram than a normal cartridge. Do we need a crack for these games or does your cart automatically fix that problem?

[djelaba]

8mbyte total memory, 4mbye max rom size, 32kbyte max save size
So no Tales of Phantasia support, and no support for games with SRAM size bigger than 32kB (about 30 games).

[Alchy]

Bad compatibility? I've got your basic original large model SNES and was thinking of getting the PowerPak for it; won't it work?It probably will, but there's some voodoo regarding which CPU/PPU/SPU combination in the SNES/SFC you have. A lot of CF cards don't work either.

[Calpis]

8mbyte total memory, 4mbye max rom size, 32kbyte max save size
Why not put in a register file to allow for 3x 16M banks, 1x 8M bank and 8M for the BIOS? With 8M you could even backup save RAM to flash. I'm positive the added register/decoder space would be negligible in your CPLD XD

This is practically a requirement for post-1993 games.


It probably will, but there's some voodoo regarding which CPU/PPU/SPU combination in the SNES/SFC you have. A lot of CF cards don't work either.
I think the PowerPak issue has to do with it using DMA to PowerPak registers. Apparently the DMA state machine varied on different revisions. If the Everdrive doesn't use DMA there won't be issues.


So no Tales of Phantasia support, and no support for games with SRAM size bigger than 32kB (about 30 games).
Wha?? Are you sure? I thought there were 2 or 3 standard carts with 1M saves.

slot for dsp? maybe...

Star Ocean will not work in any case because this game use data decompressin chip.

cart can configure sram size, so games like donkey kong works fine

saves.

ok, maybe i will implement it. seems like we have just one game who have big rom size and don't use decompressing hardware: Tales_of_Phantasia

[causticsoda]

Star Ocean will not work in any case because this game use data decompressin chip.


I think there is a Star Ocean rom which already has the data decompressed, and does not require the special chip. It is a very large rom however (96Mbit)

http://www.youtube.com/watch?v=Uy4SFfoT5LY

[KRIKzz]

oh you mean some hack i think, original star ocean just 48mib

[causticsoda]

yes a hack, I don't think the design should be changed just to cater for this rom, just giving information :)

[link83]

no support for games with SRAM size bigger than 32kB (about 30 games).
Do you have a list of these games? I googled for a list showing the largest SNES save sizes but cant find one anywhere. It would be good to know what games have saves larger than 32kB (256kbit)

[djelaba]

Wha?? Are you sure? I thought there were 2 or 3 standard carts with 1M saves.
According to NSRT, there are many games with SRAM bigger than 256 kb (32 kB). Most of them are Japanese.

Krikzzz : It is the Neviskti 96Mbit version of Star Ocean.
The best thing would be to support various memory mapping, using xml files, like bsnes (http://board.byuu.org/viewtopic.php?f=3&t=537&start=0).

[KRIKzz]

Do you have a list of these games? I googled for a list showing the largest SNES save sizes but cant find one anywhere. It would be good to know what games have saves larger than 32kB (256kbit)

i will make a tool for rom header scaning. it will generate list of games with dsp/superfx/big sram size games, etc. so soon we will know which games will not work

but cart has just 8mbyte(64mbit) of rom memory total, so only magic can help here :yatta:

[djelaba]

Here is a list (15 games) with SRAM bigger than 256 kb (I removed FX games).

[eightbit]

Bad compatibility? I've got your basic original large model SNES and was thinking of getting the PowerPak for it; won't it work?


I have the powerpak and it does NOT have bad compatibility for the record. As a matter of fact, it works great with everything except for some of the games with the soecialized chips (Megaman X2/X3, SuperFX titles) only because the hardware isn't there to do it. It does however have the DSP1 included so games like Super Mario Kart work just fine.

I love the cart personally. Still, I will probably buy one of these Everdrive SNES carts when they become available because I collect these devices ;)

[Alchy]

I have the powerpak and it does NOT have bad compatibility for the record."I have one that works so they must all work".

The incompatibilities and problems that many people have had are well documented elsewhere. If it works it's a great bit of kit - but it is not 100% compatible with all SNES/SFC consoles, not by a long shot.

[Calpis]

Here is a list (15 games) with SRAM bigger than 256 kb (I removed FX games).
Notice that if you remove SA-1 games you end up with 4 by my count. Some might look at the expense of >256Kbit RAM as excessive for 4 Japan-only games. 256Kbit are widely available and cheap. 1Mbit on the other hand are not commonly stocked, are at least 3x the cost not taking into account other unknown factors. FRAM even more obscure and for 1Mbit it looks like you'd have to go straight to Ramtron.

[link83]

I just looked at that 'bigsram' list, and as Calpis already said, most of them are SA-1 games. It looks like very few games will be incompatible with SNES Everdrive due to lack of hardware, heres a list:-

96Mbit ROM
Neviksti Star Ocean hack

512Kbit SRAM
RPG Tsukuru 2 (JP)
Sound Novel Tsukuru (JP)
Thoroughbred Breeder III (JP)

1Mbit SRAM
Kaite Tsukutte Asoberu Dezaemon (JP)

Enhancement Chip Games
List here:-
http://en.wikipedia.org/wiki/List_of_Super_NES_enhancement_chips#List_of_Super_ NES_games_that_use_enhancement_chips

If those are the only games that dont work on SNES Everdrive I dont think its much to be concerned about :-)

<EDIT> KRIKzz, have you been able to test Satellaview BS games?:-

Hello,
I just purchased one of the Everdrive MD's just now. I'm kinda excited to get it since I've seen nothing but great reviews for it. I'll be even more excited when this Everdrive for SNES/SFC is finalized and released. Keep up the great work, KRIKzz!

Just curious. Does this SNES Everdrive do NES/FC games similar to what the Everdrive MD does for SMS games?

And if we're voting on the next Everdrive after this, I'd love to see either a PC-Engine/Turbografix-16 Everdrive or an N64 one.

[MottZilla]

Just curious. Does this SNES Everdrive do NES/FC games similar to what the Everdrive MD does for SMS games?

No, it won't. SNES is not compatible with NES software. MD is compatible with SMS software because the system actually contains SMS hardware where as the SNES contains no NES hardware.

[Bootay]

Just wondering how many revisions of the SNES/SFC you've tested with, because the PowerPak has pretty bad compatibility. I'm on my third SFC and still no luck.

Actually the Powerpak has great compatibility. I tested every legit US game on it and there was only a list of 20 games that didn't work and it was all due to special graphics chips. This is 20 games out of 700. Both the NES and SNES Powerpaks are wonderful devices.

EDIT: Opps. I just realized you meant compatibility with hardware not software. Sorry. =)

[APE]

No, it won't. SNES is not compatible with NES software. MD is compatible with SMS software because the system actually contains SMS hardware where as the SNES contains no NES hardware.

The Genesis worked out as the z-80 was sitting there on the Genny mobo and was happy to be a workhorse for SMS stuffs. The SNES iirc has a CPU that is compatible with NES titles but beyond that I'm unsure of any similiarities that would allow for it to play NES titles.


I think there is a Star Ocean rom which already has the data decompressed, and does not require the special chip. It is a very large rom however (96Mbit)

http://www.youtube.com/watch?v=Uy4SFfoT5LY

Yes before Star Ocean and Super Street Fighter (was it? One of the Street Fighters) the rom's had their graphics decompressed so they could be played on emulators which admittedly was a stop gap solution and was solved with proper emulation of the required chip. You might be able to get a flash cart to load the game from a decompressed rom but I'm sure that would present it's own challenges in how to shuffle data around. Not too difficult to get something to work in software where you can modify anything you want. A bit more difficult to get functional in real hardware where limitations can become more apparent.

[Alchy]

EDIT: Opps. I just realized you meant compatibility with hardware not software. Sorry. =)No worries. Yeah, for clarity I meant compatibility with SNES/SFC consoles rather than compatibility with games - if it works the game compatibility is great, or so I've heard.

[MottZilla]

Right. SNES has a 65816 which can execute 6502 code from the NES, atleast assuming certain things are followed. It was suggested that this points towards Nintendo originally wanting the system to be able to play NES games. But really other than the same family of CPU nothing else is at all similar unless you count the way you can strobe the controllers to read them.

[/quote]
Yes before Star Ocean and Super Street Fighter (was it? One of the Street Fighters)[/QUOTE]

Street Fighter Alpha 2 uses SDD-1. Same as Star Ocean. You're correct about the emulation issues because the chip wasn't emulated. Star Ocean was hacked by Neviksti (sp?) to run without the SA-1 and taking up a whopping 96 megabits of ROM requiring an interesting cartridge mapping that only Game Doctor SF and PowerPAK support. I was told by him that a 64 megabit version might be possible as he said there is likely alot of wasted, duplicate, or invalid data in the ROM and that if someone really took their time they might make it fit into 64M. I'd like to see Street Fighter Alpha 2 hacked similarly but who knows if that will ever happen.

I would definately like to see a n64 flash cart on the market that reads standard media
Also, it would be nice to have a gbc or gg cart

[eightbit]

No worries. Yeah, for clarity I meant compatibility with SNES/SFC consoles rather than compatibility with games - if it works the game compatibility is great, or so I've heard.


Yeah, I didn't realize this either when I posted my comment. I have always used my powerpak on a standard NTSC 1st gen SNES and of course it works fine there. I love the powerpak devices, but I just wish they used standard SD media instead of CF. Not a huge deal of course, just a matter of personal preference.

I love the Everdrive for the Genesis, and you can't have too many of these great devices. The SNES version is as good as sold when released ;)

There are GBC carts out there, although it's best just to get out of the GBA or DS carts that use mini/micro-SD for them.

An N64 flash cart would be the bomb. The only major one I know of is Neo Myth (http://www.ic2005.com/shop/product.php?productid=115&cat=0&page=1), which like most of their stuff is very expensive, and stores very little. I think compatibility is good though, as special chips pretty much went away on the N64.

Interesting, Neo Myth's also expensive SNES cartridge requires an SNES or SFC cart plugged into the back. Well, when a DSP-1 game is plugged in, you can play other DSP-1 games on the flast cart. Perhaps Krikzz can do something similar? Unfortunately, any other special chip games don't work in the same way. It's rumored it has the hardware to do so, but Neo Myth folks never went any farther with it, and probably never will.

my cart will be without plug for cic/dsp donor

[YAGRS]

I'm looking forward to when the SNES cart is released. I hope that Stone Age Gamer and Kitsch-Bent get a good initial supply so that I might snag one of these early.

Are you considering making an NES cart someday? I have been considering an NES PowerPak, but I would hold off if you think you might do an NES flash cart at some point.

[MottZilla]

There are GBC carts out there,
The only GB/GBC carts out there are old style NOR Flash, none read from CF or SD.

Pretty certain this was not true. Maybe the Neo Myth SNES cart's got a FPGA large enough to try to emulate some special chips. But that's just the first tiny step. Actually emulating chips like the SA-1 or Super FX would not be so simple. Also chips other than DSP will never work as a plugin due to most of these chips having direct rom access, or even being between the rom and the console. Not the on-bus arrangement that DSP seems to have.

[WaverBoy]

I dunno, the NES PowerPak is a pretty amazing piece of hardware. Worth every penny of the $135 I paid for it, especially with the latest updated firmware. Only a handful of games that aren't compatible with it. Comes already encased in a fabulous translucent orange NES-style cartridge case and cool label to boot. But, if KRIKzz came up with a device that was compatible with all the games the PowerPak is, plus throw in MMC5 mapper support (possible on the PowerPak but not implemented yet), that would take care of all but 13 licensed US games, and would make it definitely worth considering.

i love NES, so i have plan to make cart once, but it will be very not soon. nes cart it is device which damn hard to design, so here need much more time than for sega or snes. so now you can buy nes poerpack without doubt :nod:

[YAGRS]

Cool. Thanks for letting me know. Guess I have a PowerPak in my near future :)

[link83]

Awesome work KRIKzz :thumbsup: What is the socket for at the bottom right of the PCB?

Is there any chance you were able to test hacked Satellaview games?

KRIKzz, have you been able to test Satellaview BS games?:-
http://en.wikipedia.org/wiki/Satellaview
There are hacked versions available and some versions should work on flash carts. Here is a list of BS games:-
http://en.wikipedia.org/wiki/List_of_Satellaview_broadcasts#Broadcast_game_list

Also, to quote from this post:-
http://nesdev.parodius.com/bbs/viewtopic.php?p=52136&highlight=#52136

as someone who has bought multiple flash carts and used lots of emulators, I recommend testing sram save/load behavior on large lorom games like "Ys III" and "Umihara Kawase". Most beginner SNES mapper detection schemes fail to accommodate their mapper types.
It might be a good idea to test these two games as well?

[KRIKzz]

"Ys III" and "Umihara Kawase" works fine. on the bottom side SD and USB sockets. usb will be present only on develop version for homebrew makers.
about satellaview games: give me direct link on some rom which you want test i will try run it

[link83]

"Ys III" and "Umihara Kawase" works fine. on the bottom side SD and USB sockets. usb will be present only on develop version for homebrew makers.
I think a lot of people would like USB version, will it cost extra?



about satellaview games: give me direct link on some rom which you want test i will try run it
The ROM I would like to run is "BS Zelda no Densetsu" but there are many hacked versions available and I dont know which one is best for real SNES hardware. I know user MottZilla was involved in many real hardware patches for BS Zelda, maybe MottZilla can let us know which version is best to try? :pray:

[YAGRS]

cart will be available in next few days

Great news!

I will be checking back daily in hopes of getting one ASAP.

[emu_kidid]

Group purchase again?

[nesworld]

awesome.... hopefully my paypal account is back to normal by then :-/

[redstar_dan]

I would like to ask a question. Why have you opted for SD? Rather than implement a smaller device, e.g. Micro SD. With something small like Micro SD you would not have to modify the cart shell. I would be interested to hear some reasons behind this :)

I hope this is not a stupid thing to ask.
Dan.

[MottZilla]

Because then you would have to open the cartridge up to change the SD card? That would be very annoying.

[KRIKzz]

Because then you would have to open the cartridge up to change the SD card? That would be very annoying.

you right, but i thinking about micro sd. i sure that many peoples upload games just one time, so they can put micro sd cartd and close cart shell for ever

[redstar_dan]

Because then you would have to open the cartridge up to change the SD card? That would be very annoying.

I do apologise, I fully agree with what you have written however I should have added this to my previous post;

Normally with my devices that use removable type storage, I tend to buy a bigger card, as I prefer to have all my content with me. Only updating due to firmware requirements.
The way I would personally use the Everdrive, would be to fill it up completely (or as full as possible), and not actively move content back and forward. I would not see much point in removing the card if I had a full set on the device.

I completely understand that most users will be actively moving content back and forward and that It would be easier to access the card if a slot was in place. Personally, I would love to have no slot and have a micro SD hidden away. Thats just me though :)

EDIT: Does an input exist that accepts both SD and Micro SD? If this was at all possible, the user could choose whether to cut a slot for a SD card that poked through.

[KRIKzz]

SD totally compatailable with micro SD, so i can add micro sd slot in new versions of cart

[redstar_dan]

SD totally compatailable with micro SD, so i can add micro sd slot in new versions of cart

I would certainly be very interested to see that =]

[scottzane]

so true, especially everytime Krikzz releases an awesome OS update !:pray:

[KRIKzz]

cart will fit in any shell. about gameboy games i don't know

[KRIKzz]

guys, someone can give me save file with some progress for snes donkey kong2? emulator sram save file (not save state). snes9x call it as .srm

KRIKzz,

Here's a .srm from Donkey Kong Country 2 US version 1.1.

somebody know how should be mapped big rom (48mib)? dirrect connection to address bus not works

You mean steal his design and hard work? That will likely earn you a very quick ban.

[retro]

I didn't read the whole topic

read: I couldn't be bothered to check whether my question had already been answered, even.


will you upload the pcb and parts list (and probably firmware) so someone could built it home from scratch?

Assume that, if someone's SELLING something as a complete, assembled kit, they won't want to do this. Fair enough when he's put so much time and effort into coding it.


sucks, gonna have to do that myself then.

Are you saying that you would reverse engineer someone's design and distribute it freely? That's illegal.

[ASSEMbler]

Get real.

[APE]

He is probably one of those kiddos who steals code that is freely released by Acid Mods and sells pre-programmed PICs to people to mod their controllers. I was buying chip kits from some guy before I figured out he was trying to get me to do a batch order of several hundred. When he has "a guy" working on the code for new features that, coincidentally happen to be in the todo list of some of the freelance coders, I finally got wise to his system.

People make me sick.

[MottZilla]

Byuu the author of BSNES could probably tell you this. http://byuu.org/

[xmog123x]

oh mah gawdddd. people here are so stuck up. I meant build something "like this" from scratch. You know, a memory flasher based on an avr isn't hard to do. CAUSE, why not do something for the community instead of your pocket?

[link83]

oh mah gawdddd. people here are so stuck up. I meant build something "like this" from scratch. You know, a memory flasher based on an avr isn't hard to do. CAUSE, why not do something for the community instead of your pocket?

I would say KRIKzz is doing this for the community, the Everdrive-MD sells for $65 which I personally think is a very reasonable price considering all its features. At present I dont think anyone could build a flashcart with similar features for a lower cost.

Also, why shouldn't make KRIKzz make a little bit of money out of this? He designed and manufactured it, and any extra money he makes is a great incentive for him to keep improving the OS/Menu. I'm also sure that the profits from the Everdrive-MD have at least partially funded the development of the SNES Everdrive.

[MottZilla]

Why should he hold you hand doing it? He doesn't own the idea of making a flash cart. He's not the only one that knows how and is keeping it from all of us. Anyone can make one. He did the research to design his, why should he just give that away? Plus as Link83 said, it's not like he's selling this for some really high price and making millions. So even if you went and made your own you would probably spend more money doing that than just buying one from him. The only reason to want to build your own would be if you planned to expand the design such as to include a FPGA that you would use to emulate chips like Super FX. But somehow I doubt anyone is planning on doing that.

[KRIKzz]

Byuu the author of BSNES could probably tell you this. http://byuu.org/

Yes, that's why I asked if he's gonna upload everything, cause unlike some people I've got some chips on stock and could make it for myself cheaper, without the cost of the PCB, soldering etc. Let's just end it at that. If I'll make something like this, I'll be sure to let you guys know.

[raylyd]

krikzz does good work then some people want to make fake carts
krikzz does hard work on makeing up these carts.
krikzz put me down for one i will buy one when you have these made up buddy.
i will have to get some hook ups for my snes console now and some nice controllers.
how much cutting do we have to do to fit them in cart case.

[djelaba]

Get real.

Some of you may have heard about Ikari_01's project ? He is the one who released the source for SNES CIC clone (http://nesdev.parodius.com/bbs/viewtopic.php?p=58670#58670) (used by SNES Powerpak, breaking GPL btw..). He's working on a similar project, but he intends to release everything under GPL (http://nesdev.parodius.com/bbs/viewtopic.php?p=53724#53724). So yeah, there are still hackers who are not afraid or thiefs.
I didn't intend to bash KRIKzz (I bought him a everdrive), but as everybody laughed at xmog123x's request, I thought it would be a good idea to post ;)

[ElBarto]

used by SNES Powerpak, breaking GPL btw..

If the Powerpak use the code unmodified it doesn't break the GPL licence.

[djelaba]

The source code (original or unmodified) must be available on the main web page (http://www.retrousb.com/product_info.php?cPath=24&products_id=84), or at least a link to download the source. There are no reference to the GPL on this page.

[KRIKzz]

Super Everdrive available now!!!
http://krikzz.com/severdrive.html

[gorgyrip]

Amazing. I hope there will be a group sale.

[WaverBoy]

Ooh, great news! How is the game compatibility compared to the SNES PowerPak? Will it run any of the games on the list linked below?

http://www.retrousb.com/downloads/incompatibilitylist.html

[KRIKzz]

compatibility same as on powerpack except DSP1 games
all games from this list will not work. also we can include games who use DSP1 chip. full compatibility list will be later.

[Mamejay]

So whats the next Everdrive project KIRKzz?

A PCengine cart?
Please do it!! ;)

A question about the SD card capacity. On your website it mentions only 2GB supported. Why is that?

[KRIKzz]

mmm even dont know who will be next. for a long time i want build zx spectrum clone with modern interaces as vga, ps/2 or usb keyboard, SD instead of tape and flopy, etc. aslo i thinking about flash cart for n64, gameboy, sms and game gear.

2gb because i still have not SDHC and fat32 implementation. i still use data storage code, writen for sega everdrive. once i will implement SDHC and fat 32 and then, after OS update, big size cards will be available

[Mamejay]

N64 I think will be an excellent choice for the next everdrive project.
N64 carts are still expensive here in Australia and there is not many options for the N64.

[aleomark]

HI guys, I'm making these big tread on EOL -click here- (http://www.elotrolado.net/hilo_recopilatorio-flash-carts-de-consolas-clasicas_1490286) (the most important web for scene and videogames in spanish) about all the flash cart ever made. As you can see I post in this format:

I've added both everdrive carts to my tread, I hope someone create soon a review in english for this cart and let me know in order to update my tread, as soon as possible, thanks 4 all, and congrats krikzz I appreciate your contribution to the scene.

[goombakid]

So no Mario Kart or Pilotwings then. Oh well, I can probably pick those up for a decent price somewhere else. DSP1 might be possible in the future, though?

Great job, KRIKzz! I'll be purchasing one on my next payday. How good is LiqPay?

And again, I'd love to see an EverDrive for the PC Engine/Turbografx (Turbo EverDrive perhaps :rolleyes:) Otherwise, I await to see your next project.

project.

may be i will make place for DSP1 once, but it will be just empty holes, user should be get DSP1 from donnor cart and solder DSP1 in everdrive by self hands

liqpay can send money without fee, but not all credit cards work, visa and master card accepted. and sometimes banks not allow any transactions from Ukraine (liqpay is ukrainian system) by default, so user should call to bank and ask to unlock transactions for his card

[MasterOfPuppets]

Good work! I would really like to see an N64 cart too, as all the ones out there are archaic or cost too much. Hopefully a group purchase will come up!

[link83]

Great work KRIKzz! I still think a Game Boy/Game Boy Color Everdrive would be good for the next project :nod: There has never been a GB/GBC flash cart which could use external memory cards like SD/microSD.

I would like to see an N64 Everdrive too, but there are a number of points to consider:
- The Everdrive-MD and Super Everdrive use 64Mbit flash chips, but an N64 Everdrive would need 512Mbit flash which would considerably add to the cost.
- Loading times to flash would be very long (Think about typical Mega Drive game sizes/load times and then multiply that for N64 game sizes)
- There is still no N64 CIC (Security chip) clone, so KRIKzz would have to purchase lots of N64 games from both NTSC and PAL regions for the CIC chips, or the end user would have to solder it in themselves.
...Thats not even taking into consideration support for the four different save types used in N64 games.

[aleomark]

I still think a Game Boy/Game Boy Color Everdrive would be good for the next project :nod: There has never been a GB/GBC flash cart which could use external memory cards like SD/microSD.

that's extra work but could be posible to store the saves on sd, an auto backup/load function be added

512mbit flah cost not too much
512mbit flash has more fast flashing, also n64 cpu very fast. main speed limitation for sega and snes everdrive it is slow cpu
cic it is really problem
many n64 games use external save pack. i think i can implement just one most popular save tyme.

z80 cpu not much more slow than snes cpu
i not like ram - game reloading need
may be you know how to emulate n64 CIC?
unfortunately dirrect save on SD impossible

[WaverBoy]

A pity that this won't be compatible with DSP1 games, but even so, this will be a great lower-cost alternative to the SNES PowerPak, for those that don't mind modifying their own cartridge case and can live with not having those particular games available on it.

Krikzz, you should post about this in the Brewery subforum at NintendoAge:

http://www.nintendoage.com/forum/categories.cfm?catid=22&entercat=y

I'm sure there are many there who would be interested in your product!

[MottZilla]

- There is still no N64 CIC (Security chip) clone, so KRIKzz would have to purchase lots of N64 games from both NTSC and PAL regions for the CIC chips, or the end user would have to solder it in themselves.

Actually, copiers of the time used some of kind Boot emulator so you could play various different CIC games without needing a cartridge for each as I recall. And since emulators have to emulate them it's not like you can't get information on it.

Also about 512mbit, yes if you wanted to run the... 5 games that are 512mbit, you'd need that much flash if you do it that way. However I've heard the N64 cartridge bus is extremely slow and that you could probably use a Compact Flash card directly and not need any DRAM or FlashROM to temporarily store the ROM.

[KRIKzz]

not so slow. i gues that compact flash has some protocol which should be used for access, n64 just want set address and immediately start reading. also n64 can't wait for device ready state, befor reading, as need for nand flash

backup device not emulate CIC, they just use single CIC boot code which they keep in bios and not use bootcode from cart which can de various, so just one cic can be used for any game

Sorry, didn't realise 512Mbit flash was faster :redface:

I guess the CIC is the real problem - we really need someone to decap the N64 CIC's. ikari_01 who made the Super CIC clone said they would be interested in making an N64 CIC clone but needed detailed photos of the chip die first.


Actually, copiers of the time used some of kind Boot emulator so you could play various different CIC games without needing a cartridge for each as I recall. And since emulators have to emulate them it's not like you can't get information on it.
Its not quite that simple im afraid, Nintendo used five different CIC chip revisions for each region, and each of these revisions matched to different games:-
http://n64.icequake.net/mirror/www.elitendo.com/n64/usa_boot_save_faq.html#b1

There was a "boot emulator" tool available for copiers:-
http://n64.icequake.net/mirror/www.elitendo.com/n64/usa_boot_save_faq.html#b11
This allowed you to use a different CIC revision than the one originally intended for the game, however this doesnt get around the problem of actually needing a CIC chip to begin with :crying:


Also about 512mbit, yes if you wanted to run the... 5 games that are 512mbit, you'd need that much flash if you do it that way.
Only problem is a couple of those games are some of the most popular/desirable for the system (Paper Mario, Conker's Bad Fur Day) If you include the two 512Mbit Zelda Debug ROM's to the list there are actually 7 games that are bigger than 256Mbit ;-)

[aleomark]

not only that 2, all the 5 are important games:

N64 games larger than 256 megabits
320mb: Paper Mario, Ogre Battle 64: Person of Lordly Calibur
512mb: Pokemon Stadium 2, Resident Evil 2, Conker's Bad Fur Day

I'm pretty sure that that's it.

The problem with "getting a CIC" is easily solved. Buy some of the really bad N64 games and gut them for their CIC. It's the same thing that was done for the SNES PowerPAK, Tototek Flash Cart, Other Flash Carts, etc. There are far more terrible and cheap N64 games than there will be flash cartridges sold.

[sheath]

liqpay can send money without fee, but not all credit cards work, visa and master card accepted. and sometimes banks not allow any transactions from Ukraine (liqpay is ukrainian system) by default, so user should call to bank and ask to unlock transactions for his card

I figured that out this morning. My bank flagged the transfer before it even went through. I guess that's a good thing, but I did avoid giving Moneygram all of my account info and their minimum $10 fee.

Thanks KRIKzz!

Yes all those EA Sports titles! The only thing I would say is that its not viable to produce a cart where the buyer has to solder things on.

[link83]

KRIKzz was the N64 officially released in the Ukraine? If so are N64 games easy/cheap to find? I am having trouble just finding out if the Ukraine uses PAL or SECAM for the TV system!

may be i will make place for DSP1 once, but it will be just empty holes, user should be get DSP1 from donnor cart and solder DSP1 in everdrive by self hands

I'd be more than happy to go get a donor cart and get the DSP1 installed. I'm assuming it's not possible to install it on the current Super EverDrive, though.

IF you do plan on releasing one where the DSP1 can be installed, will it be possible to have it work without the DSP1 installed for non-DSP1 games? That is, until a donor cart can be raided for the DSP1.

Also, by taking the EverDrive OS, how much modification to the code would be needed to port it to other consoles? I'm just curious since the transition between the MD and the Super EverDrives was kinda quick.

[KRIKzz]

if new super everdrive version will be have place for dsp, than cart still will be work without dsp for non dsp games.
OS can be ported very fast on other system if console CPU has some C compiller. just low level assembler part of code should be rewriten

[MottZilla]

Yes all those EA Sports titles! The only thing I would say is that its not viable to produce a cart where the buyer has to solder things on.

The buyer wouldn't do this. When they are produced, whoever does assembly would just have to get a bunch of CICs off bad N64 games and install them into the Flash Cart.

[vectrex_rox]

@KRIKzz: you going to take paypal orders?? i want to order SNES + MD version asap.
thanks

btw.: ZX Sepctrum Clone -> GREAT -> I WANT ONE !

[KRIKzz]

unfortunately i can't take paypal directly, because paypal not allow useres from Ukraine to take transfers

[vectrex_rox]

DAMN so whom i can send it ?? those shops dont have the SNES cart and also the MD cart is more expensive ;(

[KRIKzz]

they will take md carts soon, and later snes. i can receive payment only via moneygram or liqpay

[goombakid]

if new super everdrive version will be have place for dsp, than cart still will be work without dsp for non dsp games.

:pray:If you do plan on re-releasing a DSP enabled EverDrive. Otherwise, I will be investing in this current EverDrive soon.

Thanks for the reply and the great work!

[ASSEMbler]

Krikzz the snes unit when will it be fully tested for bugs?

[APE]

I wouldn't mind purchasing a bunch of cheap n64 titles to pull the CIC chips out of and resoldering them. Be a bit time consuming but I'd assume I'd be tacking on a small premium for the service for those less inclined to want to solder.

I might just wait to see if a DSP version gets made honestly, soldering that chip isn't that difficult but I don't have any donor carts atm....time to rectify this problem.

On second thought I think I'd rather have C4 support but then again I'd have to destroy Mega Man X2 or X3...that seems counterintuitive. Id suggest SuperFX but the many revisions might not work out as planned.

[KRIKzz]

Krikzz the snes unit when will it be fully tested for bugs?
already tested my be, but i physically can't test each game and each snes model.

[raylyd]

KRIKzz is the best thanks for this great hard work.

[MottZilla]

Ideally you'd want a FPGA and to emulate each chip. It would make the hardware alot cheaper but engineering or rather REing the chips would be a huge task. And if you just wanted to butcher carts for the actual chips you'd be better off making a full sized copier and charging a great deal of money for it.

[Calpis]

All this talk of cart sacrificing is making me cringe >:'(

[BM-Viper]

Sweet, finally managed to get LiqPay working! I cannot wait until I receive my EverDrive SNES. I can post up a full review once it comes.

I do have a question though, is it possible to solder on the Mini-USB connector yourself if you need it in the future?

[emu_kidid]

I'll wait for a DSP installable PCB, but fantastic work as usual Krikzz!

[KRIKzz]

I do have a question though, is it possible to solder on the Mini-USB connector yourself if you need it in the future?

you should solder usb connector, ft245 usb bridge chip and few capasitors and resistors.

[BM-Viper]

Oh okay, a little more complicated than i expected. :P

[KRIKzz]

Oh okay, a little more complicated than i expected. :P

i not so impudent for take 15usd extra just for mini usb connector (:

[ASSEMbler]

already tested my be, but i physically can't test each game and each snes model.

So pm me so we can arrange price and other specifics for group purchase.

[BM-Viper]

i not so impudent for take 15usd extra just for mini usb connector (:

I didn't think that you were. Was just seeing how difficult it would be to add if I happened to need it in the future. I assume OS updates can be done through the SD card just like the original EverDrive?

[KRIKzz]

yes, OS still can be updater through the SD card

[MottZilla]

All this talk of cart sacrificing is making me cringe >:'(

Atleast it was N64 carts. Probably the most worthless game cartridges there are due to their mass numbers and undesirability.

[ASSEMbler]

I put up a thread. Krikzz please put up some pictures.

[goombakid]

Can the Super EverDrive firmware be updated through USB also? Or is it still a JTAG update?
I only see 2 or 3 games to warrant waiting for a DSP enabled one. KRIKzz, do you have any plans to release a Super EverDrive with a spot for DSP chips?

[KRIKzz]

firmware update still only via jtag.
i have plan to make pcb with empty area for dsp1, but it will be not very soon

[goombakid]

Ah, ok.

I'm also wondering if the Super EverDrive would work on clone consoles (Looking at the Retro Duo for future purchase).

[KRIKzz]

don't know about clones. will see soon

[eightbit]

What would be better would be for the flash cart in question (aka: N64 Everdrive) to piggyback a CIC N64 cart ala "Sonic & Knuckles". In other words, have the cart expansion on top to add your own N64 cart with CIC lockout. The copiers worked this way for various functions as far as I recall (Z64) and would save peopel time and energy as all you would need to to is get ahold of an official cart to plug into the Everdrive.

Same actually can work for SNES Everdrive if it ever gets implemented. Use pass-through to plug a game like Dirt Trax or Star Fox and utilize the chip to load other titles.

Just an idea ;)

[Serantes]

KRIKzz (http://www.assemblergames.com/forums/member.php?u=59949) just my two cents about n64
time ago mame ppl decaped a cic from some n64 arcade game based, i remember that they said that the code was a PIC, so it may be worth to look at the decap and see if you can emulate it, or in worst scenario, replicate it.

[jonwil]

I think that might have been an IPL chip, not a CIC.

[MottZilla]

No, you can't. You don't understand how chips like the Super FX work. You can not "piggyback" he cartridge to run a SuperFX ROM. This does work for DSP, but not any other chips.

And yes I know about N64 Copiers doing what you are talking about. That is an option but if you can avoid having to worry about plugging in the correct cartridge to play a certain game I think that would be preferable.

[mdmx]

Hi krikzz, I have another question about DSP support:
Can I use Tototek's T-Connector with the Super EverDrive?
http://www.tototek.com/store/index.php?main_page=product_info&cPath=1_8_11&products_id=40

The T-Connector allows you to plug in a DSP cartridge. Would this work with your flashcart?

Might be a PIC for that but I don't recall it being a PIC on the cartridge's I have torn apart.

and yes i am talking about the CIC on the cart not the IPL

[eightbit]

You know, even without DSP-1 support, this cart has a few ups on the powerpak.

One thing I *hated* about the powerpak is the fact that it cannot create save files. You have to manually copy a blank save to the CF on this device and tell it to save to that file for a specific game. If the Super Everdrive handles saving like the Everdrive (I am assuming it does), that is a MAJOR plus.

Also, the powerpak has zero options and no ability to upgrade without sending it back. I see the Super Everdrive has menu functions just like the Everdrive, and the ability to upgrade the OS like you can with the Everdrive. Another major plus.

All in all, I personally think it is better for these reasons. If I want to play DSP-1 or FX games, I'll just buy them. They are cheap enough anyway ;) That said, really looking forward to the Super Everdrive!

[BM-Viper]

KRIKzz,

I've noticed that v2 of the os is out? Any chance of a changelog?

[KRIKzz]

log created

[sheath]

I just got mine in, it works great! I managed to snag a $2.50 copy of Madden '93 to cannibalize for the case. I thought about taking a vid of the process but got side tracked checking out good games.

Thanks KRIKzz.

[goombakid]

To those receiving their Super EverDrive units. If at all possible, can anyone test to see if it will work with clone consoles and report back? I'm thinking of getting a Retro Duo for backup in case my SNES finally decides to die on me.

[BM-Viper]

I'll test it on my FC Twin when the everdrive gets here. I can't think of a reason it wouldn't work.

[MottZilla]

I'll test it on my FC Twin when the everdrive gets here. I can't think of a reason it wouldn't work.

Because clones are not 100% accurate hardware clones? That would be a pretty big reason. Pretty sure the SNES PowerPAK doesn't work on clones.

[goombakid]

I'm having my hopes up. Just took a peek at RetroZone's SNES PowerPak, it says that it does work on clones, so I'm gonna say that the Super EverDrive will work with them also. Just waiting on that group buy...

[MasterOfPuppets]

Here's someone from Japan using the T-connector to play DSP games.

http://www.youtube.com/watch?v=wJfzQetP7HA

[BM-Viper]

Neat, I might have to pick up a t-connector.

[BM-Viper]

I got my SNES EverDrive today and can confirm it works on the FC Twin.

EDIT: Update to OSv2 without issue, and I've tried ToP (DeJap translation) and SMW and both work great.

[KRIKzz]

I got my SNES EverDrive today and can confirm it works on the FC Twin.

thanks for notice!

[Greg2600]

Is that the Tototek T-Connector?

[BM-Viper]

Would it be possible to do IPS patching on the everdrive? i.e you select the rom and patch and it loads it into the ROM memory.

Could be really helpful for Super Mario hacks.

[KRIKzz]

may be once...

[eightbit]

My 1st order came in today! Fantastic device! Works just as great as the Genesis Everdrive. I *really* like to feature of being able to reset from in-game back to the everdrive menu! Once again, really great job Krikzz!

[ponrev]

Question about OS-v3.
When starting, is anything checked in PCB with USB(FT245R)? Because it starts after LED blinks.

[KRIKzz]

not checking, just clean fifo buffer before os start

[ponrev]

not checking, just clean fifo buffer before os start
OK, Thanks.
I soldered FT245RL and USB Connector, Reg, Cap, LED by myself. It might be a cause. but, possible to play usually. there is no problem. :-)

[KRIKzz]

by the way, empty space for led, it is for CIC led. if led always shine, it is mean that all ok, if led blinking, it is mean that that cic not unlock system, ususally it may happen after first power on, if console region changed.in this case cic will change self gerion after next reset. if led not shine, it mean that console lockout removed by hardware mod

[BM-Viper]

I updated to OS v3, which i cannot get to flash a rom, the screen just goes black and nothing appears to happen. Downgrading back to OS v2 does make loading roms work again.

[dapsaille]

Well ...

it seems that you made another mystical cart ^^

I've already genesis cart from you and your work is really excellent.

Juste one question, i own a retrousb powerpack and there is a bug with save/load in secret of evermore (F) and (US) version like in old versions of bsnes emulator . save is ok but when you try to load save, game crash or bad stats for characters ..

Can someone try to save and load in secret of evermore on this new cartridge please :pray: ?

[KRIKzz]

i will try if you give me save file with some progress

[dapsaille]

Thanks KRIKzz but the problem happen at the first saving point, so no useable srm file is written by powerpack, it is always corrupted even if i try to load it with zsnes. could you please start a new game on your flash cart then try so save then restore your save (about 5 minutes of intro then go north and let your character die against the velociraptors, your dog will take you to a savepoint) ?

EDIT = i'm creating a srm with zsnes, you will only try to load game (works on powerpack) then try to resave to the same or a different slot then reload it (powerpack corrupt srm while writing, like older bsnes emulator).

[dapsaille]

I just sended you an email with the srm file.


Thanks ^^

[KRIKzz]

i make new save and then restart game and load save with success!:nod:

[dapsaille]

Damn ...... i hope that you will find a way to implement DSP1 so i can trash my powerpack (no response from the guy who sell it about this bug so for me .. no support from them => no support from me ^^)

Thanks for the try and thanks again for my lovely everdrive cart :p

[ceramiclion]

I will get it if its possible to implements DSP1, for now I guess I will stick witht he Wii VC.

[n64coder]

I'm a little confused about the SNES everdrive. Is the inability to play games that use DSP chips the only limitation?

If I look at this page: http://en.wikipedia.org/wiki/List_of_Super_NES_enhancement_chips there are other chips such as the SA. Can those be played? I read through this thread and this wasn't clear to me. Thanks!

[KRIKzz]

DSP1 will be inmplemented later, other chips never be supported

[cocole]

Hi Krikzz,

I was wondering if one could use RS-MMC instead of SD-card ?
The RS-MMC is shorter than the SD-Card but it's the format.
This would be a way not to cut the case.

[KRIKzz]

you can use RS-MMC, this type of cards is supported

[cocole]

you can use RS-MMC, this type of cards is supported
yay :thumbsup:

cocole :pray:KRIKzz

[rso]

Didn't even know those existed, thanks for pointing them out :)

RS-MMCs are currently available in sizes up to and including 2 GB.
Well, that looks like a perfect fit in every way. Now to see if it's a problem to get a hold of one - Wikipedia made them sound kinda rare.
Edit: Nope, they're neither rare nor expensive. Great!

[cocole]

I've received both my RS-MCC + my Super Everdrive and the combination works as a charm, as Krikzz said.
The main advantage of the RS-MMC is that you dont have to make a cut in the cart. Nothing sticks out.

[TEOL]

DSP1 will be inmplemented later, other chips never be supported

With all those clone systems reported to work with some SFX games maybe there is a way of reverse engineering a SNES on a chip to work in the cart on a real SNES for complete compatibility?

It will of course take much more time learning how clone systems work though so you can make your own chip up that will play on both clone and real hardware and getting the games mapped to work without the user playing with ROM patchers they do not understand would take some time too.

SEGA on a chip for Virtura Racing and Fighter SVC and peswedo FM sound would be nice for the SEGA version too.

To get these special chips to work would take so much money and time it would be ridiculous for such a niche market item.

The Super EverDrive is not the first SNES flash cart. The Super PowerPak has been around for quite awhile and they have got only DSP1 to work as well. It also still requires a donor chip.

All the the time and money for really just a few handfuls of games. It would be much cheaper for you to buy a Super EverDrive and then buy every game that requires a special chip separately than to pay the MSRP cost of a Super EverDrive that supported all games.

That's just the reality.

[Greg2600]

As for SNES special chips, there's a guy working on a cart that might be able to somehow emulate those chips, but he's been at it for well over a year. And he has said he isn't hugely interested in mass production.

[sayin999]

Anyone know if that t board method also works with sfx games?

[KRIKzz]

no way to run sfx games on any flashcarts

[Mqark]

Would anyone mind making a short list of the special chip games that we can't play using everdrive - obviously the Super FX games such as Starwing/fox etc, but it would be nice to know if there's anything else unexpected (just to fend off potential support issues).

[KRIKzz]

list already in internet http://en.wikipedia.org/wiki/List_of_Super_NES_enhancement_chips

[gorgyrip]

yesterday i was playing battletoads battlemaniacs (usa version) and i got a black screen after stage 4.

[Mqark]

list already in internet http://en.wikipedia.org/wiki/List_of_Super_NES_enhancement_chips

Thanks - that means there's only about 4 games out of the list that I'd want to play so I can buy the 3 that I don't already have.

(hope my Everdrive is sat on my desk this afternoon when I get into work :nod:)

[takeshi385]

this is a stupid question and may have been asked already but i have a snes everdrive ntsc-u, so i have been wanting to buy a super famicom i just want to know and i am prepared to mod the super famicom cart though can i will it be any problem putting the everdrive board in the super famicom cart shell.

[aleomark]

super everdrive is region free., you don't have a snes everdrive ntsc-u you have a snes everdrive that works in every snes

[takeshi385]

ty for the heads up

[james00617]

How do you make roms work for the super everdrive? ive tried a couple of them but none seem to work properly.

[beecee]

have you formatted the sd card properly?
ie: Full format (not quick) on PC, then format on the Everdrive, then back to the pc to put roms on it/

[derekb]

I think it is worth noting that when people tell you to perform Full Format on the SD card, they do not mean windows format, you need to dl an app such as SD Formatter, this will do a true Full format of an SD card by zeroing the data

[KRIKzz]

windows full format will be enough

[derekb]

from what I saw on XP windows full format of the SD didn't do nearly as good a job as using sd formatter, personally

also not to cause any trouble, but why does full format fix everdrive problems in some cases? seems like everdrive sd driver should be able to handle things without it

[ssj4jaxmazon]

I really want to get a supereverdrive but I can't seem to find any :( they are sold out everywhere. I've checked all the links of the KRIKzz supereverdrive page and again all sold out. I hope they are available soon since my birthday is coming up :).

Just got my SuperEverdrive from Stoneagegamer in the mail today, cant wait to start playing this thing. This my first everdrive and I dont want to mess it up. I couldnt really find instructions on how to work it so I just want to make sure I get it right
First Full format the sd card on the pc.
Then Format it on the supereverdrive
Put the roms on it
Play
Am I missing anything? Thanks
