== MMC3-like mappers with simple banking ==
== Legend for bank style ==
=== PRG ===
* 32 - Banks 32 KiB at a time
* 16+16F - Bottom 16 KiB are bankable, top 16 KiB are fixed
* 16F+16 - Bottom 16 KiB are fixed, top 16 KiB are bankable
* 8+24F - Bottom 8 KiB are bankable, top 24 KiB are fixed
* 3×8+8F - Three independent 8 KiB banks at bottom, topmost 8 KiB are fixed
* N108 - The Namco 108 set the theme that many other bank styles derive from ( a.k.a. 8+8+16F = two independent 8 KiB banks at bottom, topmost 16 KiB are fixed)
* MMC3 - The MMC3 extended the banking style of the Namco 108 ( user switches between N108 and 8F+8+8+8F = bottommost and topmost 8 KiB are fixed, middle two 8 KiB banks are independently bankable)
 
=== CHR ===
* 8 - Banks 8 KiB at a time
* 2×4 - Two independent 4 KiB banks
* 4+4F - Bottom 4 KiB are bankable, top 4 KiB are fixed
* 4×2 - Four independent 2 KiB banks
* 8×1 - Eight independent 1 KiB banks
* N108 - Set the trend for CHR banking style also. Equivalent to 2×2+4×1 = two independent 2 KiB banks followed by four independent 1 KiB banks
* MMC3 - allows the user to swap which pattern table gets the "large" and "small" banks
 
=== Outer banks ===
"Outer banks" are things you find in the [[multicart]] mappers, where individual games write to the registers of the "regular" mapper and the menu writes to a separate set of registers that chooses which game will be played. For example, Nintendo World Cup appeared on two boards that extend the MMC3 in this way: one with [[iNES Mapper 037|''SMB1'' and ''Tetris'']] and one with [[iNES Mapper 047|''Super Spike V'Ball'']]. <!-- thanks tepples -->
 
This same structure occasionally shows up in ordinary single-game mappers: [[iNES Mapper 096|Bandai's ''Oeka Kids'' games]], [[iNES Mapper 154|Namco's ''Devil Man'']], [[iNES Mapper 088|several other Namco games]], and a [[iNES Mapper 012|few]] HKOs [[iNES Mapper 014|that]] would like better corroboration.

Legend for bank style

PRG

  • 32 - Banks 32 KiB at a time
  • 16+16F - Bottom 16 KiB are bankable, top 16 KiB are fixed
  • 16F+16 - Bottom 16 KiB are fixed, top 16 KiB are bankable
  • 8+24F - Bottom 8 KiB are bankable, top 24 KiB are fixed
  • 3×8+8F - Three independent 8 KiB banks at bottom, topmost 8 KiB are fixed
  • N108 - The Namco 108 set the theme that many other bank styles derive from ( a.k.a. 8+8+16F = two independent 8 KiB banks at bottom, topmost 16 KiB are fixed)
  • MMC3 - The MMC3 extended the banking style of the Namco 108 ( user switches between N108 and 8F+8+8+8F = bottommost and topmost 8 KiB are fixed, middle two 8 KiB banks are independently bankable)

CHR

  • 8 - Banks 8 KiB at a time
  • 2×4 - Two independent 4 KiB banks
  • 4+4F - Bottom 4 KiB are bankable, top 4 KiB are fixed
  • 4×2 - Four independent 2 KiB banks
  • 8×1 - Eight independent 1 KiB banks
  • N108 - Set the trend for CHR banking style also. Equivalent to 2×2+4×1 = two independent 2 KiB banks followed by four independent 1 KiB banks
  • MMC3 - allows the user to swap which pattern table gets the "large" and "small" banks

Outer banks

"Outer banks" are things you find in the multicart mappers, where individual games write to the registers of the "regular" mapper and the menu writes to a separate set of registers that chooses which game will be played. For example, Nintendo World Cup appeared on two boards that extend the MMC3 in this way: one with SMB1 and Tetris and one with Super Spike V'Ball.

This same structure occasionally shows up in ordinary single-game mappers: Bandai's Oeka Kids games, Namco's Devil Man, several other Namco games, and a few HKOs that would like better corroboration.

ASIC mappers with simple banking

Discrete logic mappers

Only the ones not made by Nintendo.

This table describes the mappers as they existed, as opposed to any obvious oversize extensions.

† Mappers 89, 93, and 184 exist as a single IC, however their functions are trivially described using a small number of 7400-series ICs, and likely contain multiple silicon dice that were wire bonded together in the same package.

‡ Mapper 93 is technically the same 89 other than mirroring, but it only commercially existed using 8kB of CHR-RAM

* the Vs System distributed its original games as five or six 8 KiB ROMs, and decoding on its mainboard allowed banking of CHR like CNROM. It is a little disingenuous to claim that 0 ICs were necessary for banking since the same functionality is not possible on a Famicom, however, banking was incrementally free.

§ Doesn't have CHRROM, hence "-1" ICs
