PCE/TG16 HuCard Everdrive...

[Flavor]

here is photo how proto board looks. final board will be almost same, but without small tactile button, jtag connector and without white wire. also i will change sd slot layout in final revision, cuz prototype pcb fit not very good (SD card crossed with power switch)

Let me know if you want a tester. I can solder it up myself and update the POF or whatever.

I've been working on a new PCE peripheral, myself. I think I need your card to test my stuff.

You are wrong. Turbo Chip/North American card based games usually contain a small protection code to prevent them from running on Japanese systems. I have no idea why they did that exactly. It would have made sense if Japanese games had lockouts too. But on US consoles with a simple pin swapping adapter you can play all Japanese HuCards. But to play US Turbo Chips on a Japanese console you need to lift a pin on the CPU inside the console and change its connection.

Ah, I have a Turbo, thought it was the same.

i didn't said that switch for rom region select, switch only for console region select. switch should be tuned just once, and will stay in same state forever. one position for pce, another for TG16.

Ok, i thought it was for game region...

I am unsure how we will handle Turbo EverDrive at this point. There are no donor cases we can use like other carts. I have considered vacu-forming, but I am unsure how well that will work or turnout. It will have to be something we experiment with. Getting a custom case engineered and produced is too expensive and risky, especially for a less popular system like the TG-16/PCE.

There's a reason why we don't get custom shells done for any of the EverDrives. Mainly its because we don't have control over the project. From a strictly business standpoint since I don't have control over production or the rights to produce them myself (the PCBs) to invest tens of thousands of dollars into custom shells and then have something happen to KRIKzz would be a disaster.

We will see. I will have to get a finalized board first to see what I can get done.

Ok i think it is not a big deal, the pcb has already the size of the hucard and should be enough protected when inserted into the pc engine.

[KRIKzz]

Anyway, I sent KRIKzz the strings of bytes to search for (it's the same in all games) to patch out the protection so that won't be an issue.

i already used yours info. now US games really works fine on japanese pce. thanks a lot!

[antinull]

oh lord
Kirkzz you have once again delivered what we wanted
Looks like i will be buying another flashcart :D

Looking good.

Fantastic, haven't been this excited since everdrive 64. How are you going back to the menu when there is no reset button on the pc engine?

[KRIKzz]

i made reset button on the cart pcb

[YAGRS]

Color me happy. This is the Everdrive I've anticipated most since the Everdrive MD. Can't wait until it's available.

Igor, did you see my earlier question about using the Turbo Everdrive to back up the internal memory? Is that something you would consider implementing?

Will this work with PAL Turbo Grafx 16?

I have got one recently from eBay: http://www.ebay.co.uk/itm/Nec-TURBO-...#ht_954wt_1396

Yes it should work just like any other HuCard games. I'm not sure if PAL TG16 is compatible with all games, as all games were developed for NTSC.

Great work KRIKzz!

Does anyone know for certain what the deal is with this?

[MottZilla]

NEC/Hudson never produced a PAL TurboGrafx 16 so the existing machines are basically US systems modified for PAL. I assume they run at 50hz, but don't know if timing differences cause problems with any games. Other consoles often won't run some games when dealing with the opposite PAL or NTSC of the console.

It *should* work. But I can't say for 100% certain that it will play all games because the PAL system may not. If you get a US or Japanese console the EverDrive should play every HuCard game except for Populous.

i made reset button on the cart pcb

Ah, will that be standard?

No way for the Select/Run reset combination to reset to ED main screen? Just curious, since I'm not a coder.

It's easiest to think about from the programming view. No TG16 games contain PAL data. All of its known software was designed and written for NTSC use only.

That any game even starts on PAL systems is little more than an unintentional side effect.

[KRIKzz]

YAGRScurrently i don't thinking about any extra features and don't have any systems except regular th16 and pce.
Greg2600yes, resed will be in standard cart
Spankenstein yes, will work with TG16, i have exactly same system

[Spankenstein]

Thanks for confirming KRIKzz. Excellent work as always. :)

A.W.E.S.O.M.E.!!!!!!

How long until production KRIKzz? I don't know if you understand this but I NEEEEEEEEEEEEEEEED this card more than I need life :)
