Changes

* 4DO is 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.<ref name="4DOSite">http://web.archive.org/web/20161213021202/http://www.fourdo.com/</ref> It can [[Overclocking|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.

* 3d'oh seems to have lower compatibility. However, most of the more popular 3DO titles are compatible. 3d'oh has to be compiled from source.
