The 3DO Interactive Multiplayer is a 32-bit, fifth-generation home video game console released by The 3DO Company on October 4, 1993, with an initial MSRP of $699.99. It has an ARM60 RISC CPU clocked @ 12.5 MHz, with two accelerated video co-processors, "Madam" and "Clio", clocked @ 25 MHz.

The system was discontinued in late 1996, as it proved uncompetitive in the fifth-generation market.

An older abandoned emulator that never left beta. Paved the way for preliminary 3DO emulation development while spawning 4DO and Phoenix. Was open source at one point but became closed due to fear of legal issues[1].
Based on the FreeDO emulator. Seems to have lower compatibility, however most of the more popular 3DO titles are compatible. It's a source-only release, so it has to be compiled.
4DO / opera_libretro
4DO is a fork of the FreeDO emulation project, only available for Windows and no longer active. It offers features such as CPU overclocking by up to 400% of the original clock speed, making low frame rate titles (e.g., Doctor Hauzer) much more playable just like BigPEmu emulator for Atari Jaguar or xemu emulator for Xbox. Additionally, it's possible to force games to run in a higher internal resolution (up to 2x). Severe audio glitches are very common, no matter what settings are used. A libretro port named Opera is still in active development, with many of the same features. However, overclocking only allows up to 200% (unlike 4DO's 400%)[2].
A closed-source project by a long-time FreeDO contributor. It is the most compatible 3DO emulator (claiming "100%?!" compatibility). The PC versions are completely in Russian (you can download an English translation patch here). Most of the settings are translated in this picture.
Has seven preliminary 3do drivers (One for NTSC models, one for PAL models and five related to American Laser Games). Commercial games do not load in the drivers yet (As it is reported as not working and the sound is unimplemented). None of the games are playable so MAME is currently not recommended at this point.

The Phoenix emulation project is released as separate emulators for Android; this is the 3DO version. Identical compatibility to the PC version, according to the author. Requires 1.5 GHz dual-core ARM or better for full speed.
