There was also the in-between era of arcade hardware based on home consoles, like the Triforce platform (derived from the GameCube) or Chihiro platform (derived from the original Xbox). For those the easiest approach is to extend console emulators to also support the related arcade platform, or patch the arcade games to turn them back into standard console games, rather than having MAME reinvent the wheel.

Chihiro and Triforce might have had significant games, but arcade hardware based on home consoles runs much older: Master System, Playstation, Genesis, Neo-Geo, Playstation 2, NES, Dreamcast, Playstation 3, Saturn, have one (or more!) arcade counterparts.
