mapper info
« on: January 04, 2012, 08:02:53 PM »
Ahoy!

I'm writing an emulator and I've run into a problem with some games. I know there's a special mapper for SF2, and another for 384K roms. These games are working fine for me. I'm having a problem with some 512K roms. Is there a mapper involved I should be simulating? Better yet, is there a document somewhere with this kind of info?

I do not think there are any special cases aside from SF2 and Populous. Have you tried mirroring the lower 512KB of data into the upper banks $40-$7F?
