Andreas Naive, with help from Deunan Knute, Guru, and ANY, has come up with a working on-the-fly decryption for 2 of the 4 kinds of Naomi cartridge decryption. This means trojaned protection data will soon no longer be necessary to play Naomi games in emulators like MAME, Makaron, and DEMUL so your ROMs will shrink a bit. I’m doing the hookup in MAME and have some games working already, with the rest coming.

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…

The Dumping Union bought and Guru dumped Logic Pro Adventure, one of the last known games on Sony ZN-1 hardware. Here’s a few screens.
