SFEX2 boots "correctly" now too. Gallop Racer still decrypts correctly and then explodes, but bah
Further update: Gallop Racer 2 behaves identically to MAME. Pfft. Shanghai boots, and plays music and sounds perfectly. Incidentally, Shanghai decrypts some stuff on every frame. There's no way it could ever have run in Zinc the old cheese way
Yes, Strider 2 going keyless annoys me. Not having the key for Tetris the Grand Master annoys me even more.
