The '''[[gametech:3DO Interactive Multiplayer|3DO Interactive Multiplayer]]''' is a 32-bit, fifth-generation home video game console released by [[wikipedia:The_3DO_Company|The 3DO Company]] on October 4, 1993. 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.

===Comparison===
;FreeDO
: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<ref name="open to closed">http://www.freedo.org/HTML/faq.html</ref>.
:;3d'oh!
::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|4DO]] / [https://docs.libretro.com/library/opera/ opera_libretro]
::4DO is a fork of the FreeDO emulation project, only available for Windows and no longer active. It offers [[#Enhancements|enhancement features]]. 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.<ref>https://docs.libretro.com/library/opera/#core-options</ref>.
;[[Phoenix (emulator)|Phoenix]]
: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 [https://www.rlauncher.com/forum/index.php?threads/help-with-3do-phoenix-2-8.4160/ here]). Most of the settings are translated [[:File:3DO_Phoenix_Translated.png|in this picture]].
;[[MAME]]
:Has seven preliminary <code>3do</code> 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. <ref>https://github.com/mamedev/mame/blob/master/src/mame/misc/3do.cpp (Bottom of page)</ref>
;[[Phoenix (emulator)|Real3DOPlayer]]
: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.

[[Input_lag|Input latency]] will be a crucial factor, but its impact likely varies depending on the specific technique employed, it's recommended to use '''after applying the "Internal Framerate Hack"'''.<br/>While '''AFMF''' or '''LSFG''' can be used with MAME, please be aware that some visual glitches and artifacts may occur at this time.

===Mouse===
:[[Wikipedia:3DO_Interactive_Multiplayer#Mouse|Wikipedia - 3DO Mouse (Panasonic FZ-JM1 and Logitech 3DO)]]
Fewer than 20 games supported its use, some of which were optimized for the standard controller or light gun rather than the mouse. Of the 3DO games which were optimized for use with the mouse, the best known are Myst and Lemmings. The Panasonic mouse was also bundled with Konami's Policenauts Limited Edition in Japan which came with a Policenauts mouse pad.

===Home media accessories===
;Panasonic 3DO Karaoke Mixer
The Panasonic 3DO Karaoke Mixer allows 3DO owners to play a standard Audio CD, turn the vocals down, plug in one or two microphones and sing over the music. This unit was released in limited markets.
;3DO REAL Video CD Adaptor
Rare peripheral (for FZ-FV1 models) for VCD home media playback support.
;3DO Digital Video Module GPA511M
Another rare peripheral (for Goldstar models) for VCD home media playback support.

:See [[Home_Media_Player#Emulators|this dedicated page]] for more information about home media playback support for emulation software.
