In theory, I don't see why not, SMS and MK-III hardware were pretty much the same. Krikzz might have to program something to trip the SMS into SG-1000 mode. One thing I can say is that I've tried SG-1000 roms on the MD Everdrive, and the controls and sound work, just no video.

Are we looking at @ the same price as Everdrive MD?

Looks great! I might invest in this, but I'm also taking advantage of the Everdrive MD's ability to play SMS games...but this is just too tempting.

Other than the GB/GBC Everdrive and a possible N64 Everdrive, think that an NES or TG16/PC Engine Everdrive could be possible in the future? :pray:

Please keep up the great work, KRIKzz! Every Everdrive you make is awesome!

SG1000/SMS mode is entirely triggered by software, it's just a special video modes set (which was indeed removed on mega drive video hardware) so SG-1000 roms should be directly compatible, no tricks needed.

Beside SG games, there are a few SMS games that don't work on Mega Drive (with real PBC or Everdrive) so having a SMS flash card is very interesting :thumbsup:

I don't know why you'd want to do that. The EverDrive MD can already load and play SMS games on the genesis, without the need for the power base.

Oh yes, good point, forgot about the video modes. You're right, a couple SMS games don't work due to the video mode, on the Genesis. I'm extremely interested in this Everdrive. Might have to finally pull the trigger on a SMS.

Hey Krikzz, can you clarify whether this SMS ED will be usable on both SMS and Game Gear? If so, anyone know what kind of case should be used? Put it in a Game Gear shell? SMS shell?

Also, any thought given to including an FM chip on the SMS ED?

I hear about the Gameboy ED, not sure on my interest there. I have one of those EZFlash IV carts that I can play any GB, GBC, and GBA game on, though the menu software is horrible. It emulates NES, SNES, etc., too. If Krikzz is interested, an NES/Famicom would be a good challenge, but the current RetroUSB PowerPak is really nearly perfect. As for N64, that requires a lot of complexity, and from what I've seen from the guy working on it, is quite an undertaking. Plus the needs for extra chips for lockout, and likely a lot of SRAM to load the game into. I fret to say using an SD card could be quite slow.

I believe if playing SMS games through this cart and a powerbase on the megadrive you'll have the same compatibility issues, as not all SMS games are compatible with with MDs supported video modes and such as someone said earlier in the thread. For full compatibility you'd need to play on an actual MasterSystem.

i have not plane to put FM chip on cart.
1) FM have not very low cost
2) hard to buy
3) just some japanese games used it
conclusion: not a rational solution
i not trying to create ultimate solutions, i just tryin to create device with good features by good price

about SD and n64: SD slow speed that is myth. SD can transfer 24mbit/s through spi, so 21sec for load most big n64 rom, 5-10 sec for usual n64 rom. of course SD can not be connected to n64 directly, but for transfer in sram or flash SD speed will be enough
That's what I figured re: SMS FM synthesis, which is fine by me. As for N64, the guy currently working on it used CF, but he wound up having to add all this SRAM and such for game saving and loading as well. Seems to be his big holdup is testing/integrating capability to save games as original carts did. His design has resulted in quite a large FPGA. Would you have to install lockout chips taken from old games?

LeGIt

01-17-2011, 06:28 PM

If you won't supply the cart with the FM chip, would you considr preparing them so thy are ready to receive it so someone could add thier own FM chip themselves at a later date, or is this not possible?

APE

01-17-2011, 07:16 PM

Oh fuck yes.

For FM sound there are schematics to add in FM sound to an American SMS. It's most definitely one of the easier methods but I've had some difficultly sourcing chips.

SMS Power also put out a gender adapter to plug American carts into the expansion slot on Japanese SMS:

This topic got confusing quick. KRIKzz, thank you for making these (plural?) new Everdrives. I will definitely be purchasing the SMS version, as I have already purchased the YM add-on from SMS-power's guru.

The Game Gear Everdrive is also very tempting as I almost never see these games in the wild and would love to test them. This might actually convince me to finish replacing the capacitors on one of my three Game Gears so I can see what the image quality actually was back in the day.

If I may be so bold, I would suggest the product names be something in line with "Masterdrive" and "GameGeardrive". But then I refer to the SNES version as Severdrive, so what do I know.

Yes. The idea being it adapts American carts to plug into the expansion slot which I'd assume by this is a 1:1 connection with the regular cart slot. For some bloody reason there are American releases that have FM sound that didn't get released in Japan. Why they'd bother developing sound for an add-on that never came out (or maybe it was planned?) is beyond me.

I've still not done the FM mod as stated above but I'd assume it'd work just fine. I don't *think* Bock or Charles MacDonald (whichever one of those two who had them built and shipped them out themselves) still offer these for sale but I can tell you from looking at it that it wouldn't be trivial to build one for yourself. Though the construction on the one they had produced is rock solid with a thick PCB and some very strong, great looking solder joints.

The reason I asked about SG-1000 games is because of the BIOS lockout on the US/European SMS (http://www.smspower.org/Development/BIOSes), which won't run games if they don't have a special ROM header at $7FF0 (or $3FF0/$1FF0). None of the SG-1000 games have that header (and I think some Japanese and Korean games don't either), but maybe the SMS EverDrive has some way to resolve the issue.

Dynamic patching of SG-1000 roms? Probably could patch the BIOS, burn it to a compatible chip and solder it in but clearly that is a LOT more work than some code to do it for you. Particularly since it is a great selling point for those interested.

everdrive can disable all bios checks because sms bios check everdrive OS rom, later cart just can switch between OS rom and game rom. also as option i can run SMS bios before game start.
only need to know how to perform correct sms init. currently some games not work if i jump to game directrly from everdrive menu. aladdin for example.

by the way, as far is i know FM chip ca not be installed in sms cart becaue sms cart port have not audio wires

In case anybody is interested, I bought my SMS YM2413 adapter (http://s4.zetaboards.com/Whip_Ass_Gaming/topic/7848591/1/#new) from Bock last year. The sale thread is still up (http://www.smspower.org/forums/viewtopic.php?t=8714), so I would suppose he is still selling over email. I had a little bit of trouble with my 1986 model SMS, but he helped me figure things out over email.

As far as I know it is just a cartridge adapter working pin for pin with a pin on the Game Gear side getting grounded to enable SMS mode - just like the Power Base Converter.

There are at least three different Game Gear revisions that I know of which may potentially pose a problem given one revision is just a PAL model and the other two differ in chip packaging (one versus two). I don't know of any games that have a problem with one model over another but there is the matter of having TV tuner functionality only working on certain models. Could potentially be an issue for this EverDrive.

It was originally called "Master Gear" but now it is called "Gear Master". It lets you play SMS games on a Game Gear.

Nice to hear that SMS BIOS check has been taken care of. Interested to know if GG games would work through the SMS cart w/Master Gear. Might have to wait for someone who has the Master Gear to test it though.

Master Gear adapter (and any clone adapter) PHYSICALLY puts the Game Gear in SMS compatibility mode by asserting a special pin on the GG cartridge port side.

When asserted, this signal litterally transforms the Game Gear in a portable Master System i.e Game Gear games cannot work properly in this mode (limited color palette, different IO, etc) and same goes for a SMS Everdrive with GG roms.

Only possibility would be hardware modifications to the adapter (for example, a switch that control assertion of that special signal).

This would also be a good feature for the GG Everdrive to support that signal, which is pretty similar to SMS support on Mega Drive, with even better compatibility (Game Gear can handle all SMS video modes, including SG-1000 video modes)

pin42 is what you want (it's active LOW i.e 0V = GG mode, +5V = SMS mode) ;-)

if you are doing this, note that SG-1000 games on Game Gear require CRAM to be initialised (contrary to a real SMS which uses hard-wired color palette), you can find a modified BIOS and infos here (http://disgruntleddesigner.com/chrisc/segahacking/gearmasterhack.html).

The only solution I have heard is to replace every surface mounted capacitor with electrolytic ones of the same rating or higher. I was 3/4ths of the way through doing it on one of mine when I managed to rip the plate off the board for one of the caps and couldn't get anything to stick there again.

I'm sure hoping you aren't following your own advice, but you're close. You need to replace them with the same EXACT capacitance (measured in farads) but you can pop in a HIGHER voltage rated capacitor. To do anything else will likely screw up operations.

Replacing them doesn't fix the screen's brightness rather it allows the thing to simply function again. The backlight has a DC->AC inverter that knocks up the voltage for the cathode tube. In all likelyhood in this case the tube is starting to go. Thankfully you can remove the tube, remove a few components and take out out the inverter as a whole. I've experimented with replacing it with LEDs but I simply haven't found any that are bright enough and can cover the entire back of the screen as well as a solid tube did.

sheath

01-19-2011, 06:23 PM

Yes, the same farad rating, but equal or higher voltage will work. Sorry about that, I assumed KRIKzz could handle that part.

I have seen the screen brightness improved by means of cap replacements though. In fact, I was told to replace the caps first before worrying about the backlight, unless the light is just out that is. I think it was Kendrick over at nfg Forums (http://nfggames.com/forum2/index.php?PHPSESSID=og6dllpjdf5qnp1e015uopb980&), also of Rec.games.video.Sega, that told me this method works.

Its not a pin switch, its a physical mechanical switch inside the GBA cartridge slot which the original GB cartridge shape presses down, but GBA games dont press it as they have a groove at the side - you can even see it if you look in the GBA/GBA SP cartridge slot under a bright light. Your idea would also not be as simple as you make it sound as GB/GBC and GBA games run on completely different voltages - GB/GBC games run on 5V but GBA games run on 3.3V.

I dont think what your asking is really possible...and im not even sure what the point would be? :confused: There are flash carts already available for the GBA that take microSD cards if you look around, but there are none available for the original GB/GBC which is what KRIKzz is working on.

Appreciate the explanation! I'm on the fence for a GG cart, because the GG screens are just so lousy, almost impossible to play without cap replacement.

As for GBA, I have that EZ Flash IV cart, which was fairly cheap ($40 US), and it runs all GB, GBC, and GBA games. There are similar for the DS I think. While loading GBA roms is pretty standard, any other systems, from Gameboy to Gameboy Color to Game Gear to NES to SNES to Genesis, requires you to download an "emulator"/file merger. That basically adds the emulation code to a file and then stacks on the roms. So Krikzz's cart will act more naturally in navigating the menu. Also, those EZ Flash's use mini-SD, which are a pain to find.

nice glad you got that sorted

but you know you can replace the GG screen with a modern LCD there are some tuts on youtube

you might even be able to use the modern replacement LCD for the nomad also on the GG

dont quite quote me on that i think that because they are of simmaliar nature

These look great. Really happy to see a GG version.

I suppose the market might be too small, but the NGPC is lacking such a device. Thankfully the games are cheap and plentiful though.

Keep up the great work!

Very Nice, I'm very tempted to buy one...

1) is it still possible to solder a pause button, like on MD everdrive ?

2) some korean games use special mapper, it would be nice if you could add support for them some day (info about mappers here (http://code.google.com/p/smsplus-gx/source/browse/trunk/source/sms.c), list of games using special mappers here (http://code.google.com/p/smsplus-gx/source/browse/trunk/source/loadrom.c))

3) do you plan to make OS open-source (for MD & SNES as well) ? The way I see it, it could bring other people to improve the interface or customize stuff for their need, with you focusing on more interesting things i.e hardware.

i dont see whats stopping someone from writing there own OS to flash the rom

and just using the update feature in the everdrive to load your custom OS

nothing, but it's sometime better not reinventing the wheel, having a code base that we know is working is much more practical than writing everything from scratch, especially if you have to write your own FAT driver, hardware initialization routines, etc

At this point in time I would advise Igor not to make anything open source. It is very easy for others to take a board and steal his design and then customize the OS/Firmware for themselves and sell it under a different name.

This is how he makes his money. This isn't just some fun side project for him. I think its better to leave it closed (at least for now). This is just my opinion of course.

KRIKzz

02-03-2011, 02:27 PM

Eke whick pause button you mean? pause button on the system body!
i have not plans to implement korean mapper, but i think that this games can be patched for use sega mapper.
i don't want to share sources. and this have not sence. nobody not want to make own os because:
a) that is hard
b) you easy can demage cart if will do something wrong
c) custom os branch will be unuseful after nex my update because this branch was based on old version
d)md os sharing proof it - nobody not make some own OS for everdrive
but some bad china guys easy can use it for "own" things (:

i will publish docs and samples about sd(spi) and usb usage for homebrew and all

Eke

02-03-2011, 04:07 PM

No problem, I fully respect and understand your choice.

Main interest for programming my own OS was to test initial state of the console for education purpose (and emulation accuracy off course), before Everdrive software would interfere. But I guess I could simply code my own binary for that, use OS updater then revert to backup OS when I'm done

OS source (v7 I think) was available on your site and I find it very interesting, it also helped understanding how to program MD software that can make use of Everdrive extra features but since you are gonna release documentation for homebrew anyway, it's fine.

whick pause button you mean? pause button on the system body!SMS pause button off course, the one that trigger NMI for SMS games through cartridge port, which has been removed from later MD Everdrive boards (but ability to connect a switch separately was kept)... I don't see it on the SMS everdrive but is it still possible to add the switch afterwards ?

link83

02-03-2011, 04:47 PM

Great work KRIKzz :-)

Just curious, now that you have "SNES Super Everdrive" and "SMS Master Everdrive" have you considered renaming "SEGA Everdrive-MD" to "SMD Mega Everdrive" or "MD Mega Everdrive" to match?

SMS pause button off course, the one that trigger NMI for SMS games through cartridge port, which has been removed from later MD Everdrive boards (but ability to connect a switch separately was kept)... I don't see it on the SMS everdrive but is it still possible to add the switch afterwards ?
Due to demand recently produced MD Everdrive's have the pause button back on the PCB.

The Master System Everdrive does not feature a pause button because the pause button is on the actual Master System console itself! The MD Everdrive only needs it on the PCB because the Mega Drive does not have a pause button on the console, instead Sega added the pause button to the 'Power Base Converter' for use when playing Master System games:-

Thanks KRIKzz! I ordered a Master Everdrive last night. I can't wait to play through Phantasy Star again with the YM music (my SMS has the expansion). Oh yeah! I can play Outrun 3D too, awesome!

sheath

02-19-2011, 04:06 PM

I received mine today and it works great. One potential problem for others is that I had to dremel the Pro Wrestling cart casing where the everdrive passes through the cart pins on the bottom. The solder joints directly above the pins lined up directly with the plastic of the case and caused the case to bulge there without modification.

I am not certain if this would cause other users to damage their everdrive or SMS if left unmodified. I noticed it because the cart slid rather tight into the Master System cart port and fixed it.

Otherwise this is absolutely wonderful to have, thank you KRIKzz.

YAGRS

02-19-2011, 09:33 PM

You sacrificed a Pro Wrestling cart to make your Everdrive? What were you thinking? ;)

Joking, obviously, though I do enjoy that game.

I'm looking forward to getting mine. My donor will be either an extra Choplifter cart or a Great Baseball cart. Thanks for the tip about the solder joint issues. I'll see if I run across the same issue.

sheath

02-19-2011, 09:48 PM

Choplifter and Great Baseball are two of my all time favorite Master System games. :-(

I bought a cheap duplicate off Amazon, I own it complete also. We should talk about what you enjoy about Pro Wrestling though (and I saved the board). I have utterly failed to get into it in the past.

I would be interested to know if I killed a perfectly good Pro Wrestling Cart for no reason. Please do report back if you run into the same trouble. It isn't the pins themselves. Some doodads soldered above the cart pins just hit the case perfectly on a very thin line of plastic at the bottom.

YAGRS

02-23-2011, 07:45 AM

We should talk about what you enjoy about Pro Wrestling though (and I saved the board). I have utterly failed to get into it in the past.

I think I liked playing it with a friend. It was easy enough to just pick up and play. Also, when I got the game, I seemed to dig wrestling games (though I wasn't into wrestling at the time, having given up on that when I was really young). I even really liked Battle Royale for the TG-16, even with its horrible, horrible controls.

I would be interested to know if I killed a perfectly good Pro Wrestling Cart for no reason. Please do report back if you run into the same trouble. It isn't the pins themselves. Some doodads soldered above the cart pins just hit the case perfectly on a very thin line of plastic at the bottom.

I'll be sure to post back here about my experiences with my cart. May be a while, though. There were a lot of carts bought in that group buy that need assembling :)

sheath

02-23-2011, 02:22 PM

I consider Battle Royal an early party game with a wrestling theme. Good with five players, less remarkable with progressively fewer players. Pro Wrestling, I suppose, just put me off because it wasn't like Pro Wrestling on NES. I also bought Fire Pro Wrestling 2nd Bout on PCE and didn't like it because of its insane AI difficulty.

On the cart pin solder joints and SMS cart casing, I will be very interested to know if this extends past more than one cart. I was also hoping to alert Krikzz to the possibility early enough to fix it.

Does anyone here know if the SMS Master Everdrive Flash cart will work on a japanese SG-1000 Mark III console? I read that Western cartridge-shaped games are incompatible with the Japanese cartridges because of the size of the plastic case, but is the pcb also different? Would it work if I use the Master Everdrive with no plastic case on a Mark III?

Greg2600

02-24-2011, 07:54 PM

Japanese Mark III/SMS have a different PCB board than the rest of the world. You'd need a cartridge converter, which Tototek sold for pretty cheap. They are out of stock though.

Pannolino

02-26-2011, 04:52 PM

so would be possible to use a converter plus the SMS Everdrive and get japanese rom work like mmm Ys?

anyone has tried this out?

what about with the FM compatibility? (since i.e. Ys is a game that use the fm synth)

KRIKzz

02-26-2011, 05:10 PM

casr not need adapter for run japanese games on US or EU systems. adapter need only if you use japanese systems.
FM synth will be work on japanese systems because they have fm chip, on other world systems will not work

Pannolino

02-26-2011, 08:27 PM

yeah, what i meant is that i want to play the original japanese rom on the japanese system to get the enached FM synt
so to use the SMS Everdrive on Sega Mark III you only need this adapter?
just a metter of pinout right?

KRIKzz

02-26-2011, 09:10 PM

i can't give a warranty until this not tested by me or by some other people, but i pretty sure that card will work fine via adapter on your japanese system

I had similiar problems with 256mb card and everdrive. I've formatted full with FAT and 16kb block.

The only information I can add here, don't know if this will be useful.

Everdrive have a file per folder limit of 199 files. At least, for me.

Here's a bit of trivia I found re: FAT32 (the standard format for memory cards):

A FAT32 directory can have 65,536 directory entries. Each file and
subdirectory takes from two to thirteen entries, depending on the
length of its name, so those entries can disappear long before you
think you've used them all up. Your total of 22,657 files could very
easily use 65,000 entries.

I expect you have quite long file names if you're using the standard sets everyone seems to use, so it could be you've exhausted the maximum number of entries you can have.

everdrive carts does not support FAT32 only FAT16. 200 files limit is everdrive limit not FAT.

everdrive carts does not support FAT32 only FAT16. 200 files limit is everdrive limit not FAT.

My mistake: in that case you have 32,736 FAT entries which, in the worse case scenario means you may only have 2,518 files and directories available to you on FAT16, unless I've interpreted what was said incorrectly. However, that wouldn't explain how you can get the files onto the card in the first place. :shrug:

I don't see how the 200 files limit is important to the conversation, as it's directories that have gone missing, not files within a directory. EDIT: Oh, sorry - I didn't spot indask8's comment. Just ignore me. :-P

Thank you for the answer, I'll try again tonight if I have some spare time and post the results (I 've only done quick format via panasonic sd formatter, this is maybe the problem, I'll try with windows formatter with full format).
If you have the panasonic sd formatter its better to do a full format with that, since its better suited for SD cards than the built in windows formatter.

Maybe I gather some info here. There reason why (probably) you have to format SD card in evedrive is probably windows format that does not format by default in FAT16 but in FAT32. So to avoid confusion Krik wrote format option in everdrive. If you know what to do you don't need format in everdrive. You can format in standard windows tool with options: FAT and 16 kb block. I tested this in windows 7. I see all files and all (32X, SMD, SMS) directories. Also in every directory I see all files (biggest dir. - SMD has 169 files). BUT when I received both SNES and SMD cards I format both cards first in PC then in everdrives and... It didn't work ! During copying message at about 80 files I've received message that I cannot copy any more file. When I put card in everdrive I've noticed that about only 46 files I can see and no more. I've format again strictly with instruction and this time make some subdirectories but again in each directory I've seen also first 43 to 46 files and no more. That's why I decided to do my own format and I succeded.

I'm back from work, I ended up trying windows full format (FAT16) and it worked perfectly.

I can browse every files I have on my GG everdrive now. :)

Hey KRIKzz, retrogate still don't have the game gear everdrive :(

Out of stock, will it be available anytime soon ?

This is probably a strange one...

Is it possible to play some SMS on the EverdriveGG, then pop the same flash memory card into the EverdriveMD (via adapter) and continue playing your SMS games with the same save files?

If not, would it work in the SMS?

KRIKzz

genesis flashcart and emulators use not same data format as sms. need to crop each second byte for port save file to sms, and add dummy bytes for port save from sms to md

Just to let everybody knows I ordered mine :)) Both, SMS and GG.

In 2 months more or less I should receive it (yes the brazil custom sucks).

Can you play GG games on the master system ?
Maybe modifying the rom ?

I would like to play game gear games on my tv, without the game gear itself.

Here is a hardware hack you can do, I found this by searching over an hour on the net. Unfortunately the source code link no longer works for the microcontroller.
http://members.iinet.net.au/~stinkyfist/reviletim/ggtv/ggtv.htm (http://members.iinet.net.au/%7Estinkyfist/reviletim/ggtv/ggtv.htm)

Maybe KRIKzz can look at what chris mcovell from the previous link wrote about adapting GG games to the mega drive with software ( http://www.chrismcovell.com/segahacking/gg2sms.html ). I personally would pay extra for this "Special" os upgrade:

Intercept the GG game's reading of the GG "Start" button and remap it to a button or combination of buttons on the Master System.
Modify the palette-writing routines so that they write at most 32 bytes (the size of the SMS palette), rather than 64, to the palette RAM. Palette fading, cycling, and other subroutines will also have to be modified.
Remap the GG's 12-bit palette down to the SMS' 6-bit palette. Adjustments will probably have to be made to make it look good.
Insert or reroute code so that the Pause interrupt vector at $0066 will deal with the Pause button on the SMS. Many GG games have code that just barrels past $0066 because this sort of interrupt doesn't happen often on the GG.
Edit out all writes/reads to the GG ports $00-$06. Writing to these ports can crash the system!
...and undoubtedly something I've forgotten...

As you can see, this is not a task for absolute beginners. It involves a bit of hacking, and a bit of Z-80 programming and trickery. If anybody wants to try out this type of hack, you can see what you have to do. Good luck.

yeah, I've saw it in the past when I was searching for the hacks but.. it's too much knowledge needed at least to me.

Hope someone, someday converted the whole set of GG to SMS.

You cannot do that by "OS upgrade", only way is to hack every game and do those modifications. This can't be done automatically as every game programs are different.

Are compatible the Light Phaser with the SMS Everdrive?
I try load SMS Light Phaser compatible games in my MD Everdrive, but don`t work. Detect the trigger but don`t sincronyze with screen..

It works fine here.

The 3d glasses also work.

3D works with the Power Base Converter of course, not simply a Genesis/MD.

Question, does anyone know of a tool that can patch SMS and GG ROM's directly with PAR (Pro Action Replay) codes? I have the "CCCGP" tool but both the SegaMasterSystem and GameGear are not supported. I'd buy a PAR but they are nearly impossible to find at any price.

I've also tried GGConv to swap the PAR codes to GG codes and then tried patching the ROM using ucon64 but without success as the GGConv application put out triple pairs yet

Trying to make a ROM permanently start on level 9 was a follows:
PAR=00C0-2309 -> GGConv -> 090-C0F-6E6
"ucon64 --sms --gg=090-C0F-6E6 alex.sms"

But the game starts on level 1 as it always has whereas loading the PAR code into fusion starts on level 9 as expected.

What's the current status of SG-1000 support on the Game Gear? Is it possible to set up SG-1000 games with the correct palette, as seen on other flashcarts (http://www.chrismcovell.com/segahacking/gearmasterhack.html) (albeit with a fair amount of hassle)? Are games that use additional RAM supported, i.e. The Castle?

I'm getting my Game Gear recapped soon, so am starting to think about pulling the trigger on my third EverDrive (I have the Genesis and SNES models). Being able to play SG-1000 games with the correct palette on real hardware would be a big plus.

i don't have a cart right now for test, and i can't remember if i tested before, but if os will recognize sg1000 rom as sms rom and gg vdp has sg1000 support, then will work.

The GG VDP does have TMS9918 support, but I think it may need a palette setup command to display correctly. The thing I linked above (see here (http://www.chrismcovell.com/segahacking/gearmasterhack.html)) alludes to the issue, but I'm not sure if any of that is specific to the Tototek stuff.

And: thanks for the super-quick reply! :D

everdrive gg not need some physical switch like this, because cart can control those line, and do all work automatically. switch need only if you will be use sms everdrive and master gear converter

Hmmm, OK, but how does that relate to the CRAM palette setup issues described (for example) here (http://www.smspower.org/forums/viewtopic.php?t=8224)? Have those already been taken care of by the EverDrive-GG BIOS? It sounds like all the colors will be too dark to see if the defaults are left in place.

I apologize if the question is obtuse (dumb) or if I'm not understanding something.
