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.

|---|---|---|---|---|---|---|---|---|---|
| 0 | 0 | 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 | |

ASIC
None of these ASIC mappers has bus conflicts.
