Turbo Everdrive 2 as a Super System Card
« on: November 22, 2015, 07:54:44 AM »
I've got a patch for the US Super System Card that should allow the TED2 to be used as a Super System Card on a US TurboGrafx or a PCE briefcase.

Unfortunately, I don't actually have a TurboGrafx CD setup to test this.

I'm looking for a volunteer with a TED2 and a TurboGrafx CD to do a test.

Any volunteers?

Wow if that works that would be fantastic seeing how much the US system card 3.0 goes for.

If I had a TED2 I'd volunteer.  I've been on the fence about buying one, if this patch works that may push me over  8)

This patch also acts as a 512KB RAM expansion that can be used for translations/homebrew, and it means that you can just leave the TED2 inserted all the time and play pretty-much-all the HuCard and CD games (except for Arcade Card games).

It seems to be working OK on my DUO, DUO-R, SuperCDROM and PCE Briefcase ... but it needs more people to test it, on all the different systems.

It is possible that I would be better off basing the patch on the Japanese Super System Card instead of the US version, but we won't know without having more people test it.


I have a TED2 and a PCE briefcase if that will help.

Thanks, I'll PM you.

works great so far on my pce briefcase.  tried both a 2.2 and 2.4 version everdrive.  only had time to load up the dracula x intro but it plays flawlessly.

Thanks for doing the test, I'm glad that it worked.  :D

I've looked around a bit more and found this old thread ...

"Couple of system card questions"
http://www.pcenginefx.com/forums/index.php?topic=4064.msg64037#msg64037

It suggests that there are a couple of games that don't work well with the US System Card, so I'll get the patch working on the Japanese System Card too, so that people will have a choice of what to use.

US 3.0 card price is based on it being rar3z. This is just a convenience so that you don't have to take the TED out when you want to play CD games.

When it does the Arcade card, I'll lift my head up. Best solution ATM is one turbob with the everdrive in for Hu games and next to it another with an Arcade card for CD games.

And if you don't have 2 turbobs, you should go buy another or 7 right now. And/or not bother with Arcade games coz there's hardly any good games for it, and certainly not for cheap.

Yeah, going with the Japanese Super System Card makes more sense, PC Engines seem a lot more common.

Whenever that new patch gets posted, I could test it with a Turbo Everdrive 2.4 and PCE Duo-R (assuming the Turbo Everdrive makes it here).

No point on a Duo-R Duo or Super cdrom2 as they are already have V3.00.
If you load up the original bios onto a V2 everdrive it works, the rams already there.
I use it like this all the time as it saves taking the Everdrive out.

I guess this is only worth doing for any setup that is not native V3.00.

I have a briefcase and V2.4 card to test.

It's also needed for future homebrew/translations that need access to the extra ram on a TED, stupid card, etc., so testing is useful across all hardware configurations.

 Actually, all systems need to be tested. This isn't just a 3.x bios - this gives the system more ram than SCD 3.0. 512k vs 192k.

This is an exclusive format which will likely support many future translations.

Arcade Card games are cheap and the DUO card is too. Especially compared to Turbo games.

NO!!! Please do NOT do this!!!

Some information has come to light recently that strongly suggests that doing this is a VERY-BAD-THING™.

All indications are that running an un-modified Super System Card image on the TED2 will cause bus-fighting between the TED2 and the built-in 192KB of SCD RAM.

It looks like the SCD RAM wins the fight, and that it works ... but you are putting unusual stresses on both the built-in RAM chip and the TED2's RAM/level-shifters.  That is a bad thing, and may well lead to premature failure of either the TED2 or the console itself.

The patch that I've done fixes the problem so that there is no bus-fighting, and so that it is safe to use the TED2 to run CD games.

It is actually more important for DUO/DUO-R/SuperCDROM owners to use the patch than it is for Briefcase owners to take advantage of the ability to use it as a Super System Card.

See this thread in the Development Section for details of the problem ...

And this thread for the patch itself (now for both Japanese and USA Super System Cards) ...

P.S. It is possible that KRIKzz worked-around this issue in his hardware ... but all the indications lead to the conclusion that he's not done this. After all ... the card was never designed for, or meant for, running CD games.

Does this apply for v1 as well?
