Mapper numbers above 255 exist only in NES 2.0 headers (header). The NESdev Wiki’s mapper grid divides them into plane 1 (256–511) and plane 2 (512–767); this page lists every number that has a wiki page, with what the page’s introduction says it stands for, and ends with the numbers that have none. Each number links to its page, which holds the register layout; those layouts are not copied here. Numbers 0 to 255 are on the iNES mappers page.
