byuu says: Fixed up the PPU to be as close to cycle-perfect as possible. Fixed RMW to write twice instead of read twice. Ryphecha added AOROM and fixed up MMC1. Have CNROM too, but I need to rethink the mapper/board distinction. Apparently the same logic IC is used in both AOROM and CNROM, and it's just a matter of routing the pins to it. I need to consider how crazy it'd be to emulate the logic IC and have boards simply reroute pins to it. If it's too much work, we'll just treat mappers as board + logic IC combinations. We'll see. |
