Chipping away

Guru dumped an alternate version of Time Crisis 2 with an interesting twist: the game normally runs on plain System 23, but this version runs on Super System 23. Olivier Galibert’s doing some investigative forensics to work out exactly what the differences are (games from one will run on the other without 3D, so it’s not just the CPU speeds). In the meantime I’ve beefed up the driver a bit. The System 22.5 (“Gorgon”) games now have 2D video hooked up, and both the 22.5 and System 23 games now have emulated JVS I/O boards that they properly communicate with (had to fix a bad H8/xxxx CPU core bug to get that going). In the case of Final Furlong, that was sufficient to convince it to go farther…
