This article compares the capabilities of several Nintendo mappers.
Discrete logic
All of Nintendo's discrete logic mappers have bus conflicts except some revisions of 7.
iNES | Chips | Boards | Max PRG | PRG banks | Max CHR | CHR banks | Mirroring | PRG RAM? | IRQ |
---|---|---|---|---|---|---|---|---|---|
0 | 0-1 | NROM | 32 | 8 | V/H hardwired | Rare | None | ||
2 | 2 | UNROM, UOROM | 256 | 16 + 16F | 8 | V/H hardwired | No | None | |
3 | 1 | CNROM | 32 | 32 | 8 | V/H hardwired | No | None | |
7 | 1-2 | AxROM | 256 | 32 | 8 | 1 | No | None | |
13 | 1 | CPROM (U) | 32 | 16 | 4 + 4F | V/H hardwired | No | None | |

66 | 1 | GNROM, MHROM | 128 | 32 | 32 | 8 | V/H hardwired | No | None |
180 | 2 | UNROM | 256 | 16F + 16 | 8 | V/H hardwired | No | None |
ASIC
None of these ASIC mappers has bus conflicts.
