======================== = Mapper 077 = ======================== Example Game: -------------------------- Napoleon Senki Notes: --------------------------- This mapper uses an 8 KiB SRAM to provide both 6 KiB of CHR-RAM and four-screen mirroring. Registers: (** BUS CONFLICTS **) --------------------------- $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 $2000-$2400 $2800-$2C00 +-----------+-----------+-----------+-----------+-----------+-------------+ | $8000,ROM | {1},RAM | {2},RAM | {3},RAM | {0},RAM |Internal VRAM| +-----------+-----------+-----------+-----------+-----------+-------------+ When making an emulator, you do not need to care about the specific order of the CHR-RAM banks: just provide 10KiB from $0800-$2FFF.
