Stumbled back across this, and I hate leaving threads without resolution.For anyone possibly wondering the same thing I DID get it to work.I setup a barebones “RetroArch - Alt” installation by copying over only the necessary files from my normal RetroArch.Then in RocketLauncher I just created a “RetroArch - Alt” emulator and pointed it towards the same module as RA.I then put the 2.0 card in RA-Alt’s system folder and voila!Now I get the proper TurboGrafx-CD loading screen on those games, and the JP one on the PCE-CD games. Similarly, I believe anyone playing a game on a TurboDuo (which as I recall didn’t use a system card for the CD BIOS and just had the 3.0 BIOS built-in) would always see the Super CD-ROM^2 BIOS screen before booting a CD game. There’s nothing “wrong” about using the Super CD card (i.e., the 3.0 rom) with ‘normal’ CD games that don’t require it as it was 100% backwards compatible as far as I know - I certainly never bothered to use the older 2.0 card that came with the Turbo CD once I got the Super CD card, unless I explicitly wanted to see what a Super CD game’s error message was with the older card (and as you noted, Dracula X has one of the more amusing ones). I owned a TurboGrafx-16 with CD add-on, and later on got the Super CD card so I could play Super CD games on it (actually I still do it’s just not hooked up at this point in time) so I know something about this. I could be completely way off bass here though.I can’t say anything about the bios screen because I use a patched version of the syscard3.pce that bypasses the boot screen and I have had no problems loading any pce, supergrafx or cd game I have thrown at it./QUOTEI hope you’l forgive my ignorance, but “Arcade Card”? What is that, exactly? I’m still pretty new to the NEC line of systems. QUOTE=lordmonkus 46246I might be wrong here but I think the games that aren’t compatible with the 2.0 bios are games that require the “arcade” card.
