emulator

In the MMO genre, an emulator is a playable, private version of an MMO run by players independent of a game studio. Both sunsetted and extant games are emulated with varying degrees of moral and technical support from the community and the studios; some develop their games better than the original and even attempt to charge fees or take donations. Despite the claims of emulator runners, private emulators are generally illegal under DMCA laws and violate the terms of service of most online games, but some studios and many players choose to look the other way.
