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.
