:4DO is a fork of the FreeDO emulation project and is , only available for Windows. The and no longer active, with the website has been being shut down and the most recent release is a many years old<ref name="4DOSite">http://web.archive.org/web/20161213021202/http://www.fourdo.com</ref>. It can offers features such as CPU [[Overclocking|overclockoverclocking]] by up to 400% of the original 3DO clock speed, which makes making low frame rate titles (e.g. , [[wikipedia:Doctor_Hauzer|Doctor Hauzer]]) much more playable. It allows upscaling the game Additionally, it's possible to force games to run 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 renamed to named '''Opera ''' is availablestill in active development, with many of the same features. However, though overclocking options present only allows up to 2.0x speed 200% (unlike original 4.0x4DO's 400%), that still may seem slow<ref>https://docs.libretro.com/library/opera/#core-options</ref>.

: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 [httphttps://www.rlauncher.com/forum/showthreadindex.php?4160-Helpthreads/help-with-3DO3do-Phoenixphoenix-2-8 .4160/ here]). Most of the settings are translated [[:File:3DO_Phoenix_Translated.png|in this picture]].;3d'oh!:Based on the FreeDO emulator. Seems to have lower compatibility. However, however most of the more popular 3DO titles are compatible. It's a source-only release, so it has to be compiled.

:Has four seven preliminary <code>3do</code> drivers (two One for the NTSC/PAL models, one for the BIOS, PAL models and one for the unreleased M2 versionfive related to American Laser Games). Commercial games do not load in the drivers yet (as As it is reported as not working and the sound as is unimplemented) but MAME supports the arcade hardware.<ref>https://github.com/mamedev/mame/blob/master/src/mame/misc/3do.cpp (Bottom of page)</ref>

: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.
