iNES Mapper 000 is used to designate a board with up to 32 KiB PRG ROM, 8 KiB CHR ROM, and no mapper hardware.
The most common board like this is NROM; others include RROM.
In addition, it is used for demos with up to 32 KB PRG ROM and 8 KB of CHR RAM which would otherwise not be supported on a standard NROM board. In theory, BNROM (iNES Mapper 034) might be a more appropriate choice for these demos.
In May 2012, the NROM-368 extension was proposed, allowing 46 KB PRG ROM.
Here are Disch's original notes: ======================== = Mapper 000 = ======================== aka -------------------------- NROM "no mapper" Example Games: -------------------------- Ice Climber (J) (RROM) Excitebike Balloon Fight Super Mario Bros. Notes: -------------------------- No swapping of any kind. All slots fixed, mirroring is hardwired, etc.
