The master of unlocking

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.
