(→‎Discrete logic mappers: add all the various things we've incorporated into the wiki over the past several months)
(weave MMC3 and non-MMC3 ASIC tables together. add legend. A few other recommendations from koitsu)
Line 1: Line 1:
== 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 fixed, 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
* 4×2 - Four independent 2 KiB banks
* 8×1 - Eight independent 1 KiB banks
* N108 - repeated many times; 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

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 fixed, 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
  • 4×2 - Four independent 2 KiB banks
  • 8×1 - Eight independent 1 KiB banks
  • N108 - repeated many times; 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

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
