Here are Disch's original notes: ======================== = Mapper 077 = ======================== Example Game: -------------------------- Napoleon Senki Notes: --------------------------- This mapper has 4-screen mirroring! Also, it has 8k CHR-RAM in addition to any CHR-ROM present. I'm unsure whether or not this mapper suffers from bus conflicts. Use caution! Registers: --------------------------- $8000-FFFF: [CCCC PPPP] C = CHR Reg (2k @ $0000) P = PRG Reg (32k @ $8000) CHR Setup: --------------------------- CHR-RAM is fixed at $0800-$1FFF. CHR-ROM is swappable at $0000: $0000 $0400 $0800 $0C00 $1000 $1400 $1800 $1C00 +---------------+---------------+---------------+---------------+ | $8000,ROM | {0},RAM | {1},RAM | {2},RAM | +---------------+---------------+---------------+---------------+
