Originally a port of 4DO to libretro but became a proper fork after 4DO became inactive and trapexit started refactoring and enhancing the codebase.

http://freedo.org

The first 3DO emulator. Was partially open sourced on 2010-11-09. Used as the core for all open source emulators. No longer maintained.

It appears that FreeDO 2.X is a different codebase from 1.X and may have been the base for the Phoenix 3DO emulator. The FreeDO code released is definitely not from the 2.X branch.
