From Emulation General Wiki
3DO Interactive Multiplayer was a game console released by the 3DO Company in 1993. Due to the unpopularity of the system, the emulation scene is almost non-existent. However, there are a couple of emulators available.

|4DO||Windows, Multi-platform[N 1]||188.8.131.52
|FreeDO||Windows, macOSx||v1.9 beta(?)||✗||✗||✗|
- Only available outside of Windows as a libretro core (e.g. RetroArch).
- A newer, 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.
- A fork of the FreeDO emulation project, but the standalone version is only available for Windows. The website has been shut down and the most recent release is a year old. It can overclock up to 400% of the original 3DO clock speed, which makes low frame rate titles (e.g. Doctor Hauzer) much more playable. It allows upscaling the game in a higher internal resolution by up to 2x, but the game is still only rendered at 480p. Severe audio glitches are very common no matter what settings are used. A libretro port is also available, though overclocking options are not present.
- 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.
- Has four
3dodrivers (two for the NTSC/PAL models, one for the BIOS, and one for the unreleased M2 version). Commercial games do not load in the drivers yet (as it is reported as not working and the sound as unimplemented) but MAME supports the arcade hardware.
- 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. 
- The Phoenix emulation project is released as separate emulators for Android, this is the 3DO version. Identical compatibility to PC version according to the author. Requires 1.5 GHz dual core ARM or better for full speed.
