If this is based on FCEUX source then shouldn't it be rather like that:
- CPU $8000-$9FFF: 8 KiB switchable PRG-ROM bank selected by writing to $6000.
- CPU $A000-$BFFF: 8 KiB switchable PRG-ROM bank selected by MMC3 register $07
, or fixed to last bank if PRG A14 inversion is active - CPU $C000-$DFFF: 8 KiB PRG-ROM bank, fixed to the second-last bank, or switchable PRG-ROM bank selected by MMC3 register $06 if PRG A14 inversion is active
- CPU $E000-$FFFF: 8 KiB PRG-ROM bank, fixed to the last bank
, or switchable PRG-ROM bank selected by MMC3 register $07 if PRG A14 inversion is active
- PRG Bank Register ($6000, write) - Mask: Probably
