- C = This memory is not in the NES but on the cartridge board. It can be CHR ROM or CHR RAM.
- N = Mirrored nametables, in a manner controlled by the cartridge board (see Mirroring)
- P = Palette mirror
- R = Mirror of $2000-2EFF (N)
- F = Mirror of $0000-3FFF
Note: First draft of the PPU memory map. Taken nesdoc format as example
