Banks

  • CPU $6000-$7FFF: 8 KiB PRG-ROM, hard-wired to second-to-last bank
  • CPU $8000-$9FFF: 8 KiB PRG-ROM, switchable
  • CPU $A000-$BFFF: 8 KiB PRG-ROM, switchable
  • CPU $C000-$DFFF: 8 KiB PRG-RAM
  • CPU $E000-$FFFF: 8 KiB PRG-ROM, hard-wired to last bank
  • PPU $0000-$1FFF: 8 KiB of unbanked CHR-RAM

Registers

$8000-$9FFE (even)

Select bank register number

$0-$5: No function
$6: Select 8 KiB PRG-ROM bank at CPU $8000-$9FFF
$7: Select 8 KiB PRG-ROM bank at CPU $A000-$BFFF

$8001-$9FFF (odd)

Data for bank register selected by $8000-$9FFE (even).

  • Mirroring is hard-wired (to Vertical in Fūun Shōrinken's case).
  • The register layout indicates that an MMC3 clone is being used, connected in a restricted manner.
