|Most icons next to mapper numbers refer to publishers.
Nintendo-made boards with numerous publishers get the Nintendo icon; Nintendo-made boards dominated by one publisher get that publisher's icon.
Other icons refer to status:
* [[File:Mfr icon Bad.png]] This mapper is "bad": it was used for something other than an actual cartridge. Some are [[mapper hack]]s designed for early disk-based copiers. Others are duplicate mappers that were assigned by mistake.
* [[File:Mfr icon Pirate MMC3.png]] "Pirate MMC3" mappers. Many are used for unauthorized [http://tvtropes.org/pmwiki/pmwiki.php/Main/VideoGameDemake demakes] of 16-bit fighting games.
* [[File:Mfr icon pirate.png]] Mappers used primarily by illegally copied games, usually multicarts, sometimes single-game mapper hacks.
* [[File:Mfr icon homebrew.png]] Mappers developed by members of the NES homebrew scene for cart releases
* [[File:Mfr icon Generic.png]] Mappers for which we have some information but no identified manufacturer.
* [[File:Mfr icon Missing.png]] Mappers that are not yet documented on this wiki. Do not assume undocumented mappers are currently unassigned; consult the Nestopia and Nintendulator source code.
