TED 2.4 Patched Syscard Bios on Turbo Grafx CD unit
« on: September 05, 2017, 10:58 PM »
I recently bought a USA Turbografx 16 with the CD attachment.
It came with the original USA system card not the Super System card.
The original physical card works fine for playing CD games and they run great.

I have read that the Everdrive can be used to load the patched super system bios and play Super CD games.
I have the new patched bios that I got from your previous thread (TED2 3.01) however when I try to load a CD using this bios, I get a message saying "Please Set Disc!" and it refuses to load any games.
I am using the 2.4 model Turbo Everdrive. None of the other bios files I have found online will load any CD games either. I would really like to avoid buying a physical super system card if that is possible.

How can I get CD or Super CD games to load on my American Turbo Grafx CD unit using the Turbo Everdrive and a system card bios?
Maybe I am missing something obvious.

Any help would be greatly appreciated.
I am pulling out my hair over this and I dont have much left as it is.

Thank you!

The TED can't replace a Super System card. It can load the BIOS rom but unless you have a Super CD-ROM^2 you won't have enough CD ram to play Super CD games. You need either the Super System Card or a Super CD-ROM^2 unit.

Ok I was afraid of that.
Thank you for clarifying.

I was obviously confused on how all this worked.

Much appreciated.

This video would suggest otherwise :

I only heard Elmer's patch enabled the ram for homebrew use, not for Super CD. Maybe that disc doesn't really require Super CD as it suggests.

Are you using a CDR/W? That error is usually from the laser not reading the media. If you are using CDR, try burning slower or using other media. Another option is to tweak the pots on the laser. A Google should help you out.

I think you are completely wrong on this. It can indeed be used for a SSC. It cannot be used as an Arcade Card.

I think Krikzz used to say it doesn't have enough ram for Super. Is that with or without Elmer's patch? I don't have a CD-ROM^2 only Super CD-ROM^2 so I can't test.

I think that was v1. v2 does have enough, nothing to do with Elmer's patch. What the patch does (and you SHOULD use the patched version) is that it prevents excessive access and use of the chip, extending it's life.

He mentioned something about enabling the ram for homebrew use as well.

It got buried, I found it: https://krikzz.com/forum/index.php?topic=3640.msg34306#msg34306
The hardware damaging bus conflict is explained, and patches for both Japanese and USA version of the card exists. Note that the USA version of the Super System Card isn't compatible with all games but the Japanese version is (except Altered Beast CD version which requires System Card 1.0). I don't fully understand the ram thing, but I could be wrong about TED v2 not having cd ram.

Someone should put all this information and patch in a sticky before it's buried too far to find again.

There is a Japanese revision of Altered Beast that works with all system cards, and thus works with the patched EverDrive v1.0 bios. Search for: "Juuouki (Japan) (HA10109)"

I know there's a patched rom of the Super System cards but is there also one of the normal CD ones?
