Ultima III: Exodus: 4 Open Source Clones Compared
Anteform and Minima are both original PICO-8 games styled after the 8-bit Ultima titles rather than remakes of Ultima III itself — Anteform tells its own horror/detective story, and Minima has its own plot set in the land of Miskatonia. ult3src and Ultima 3 Disassembly are a different kind of project entirely: technical reconstructions of the actual game, a Game Boy Color reverse-engineered port and a from-scratch NES disassembly, with the latter explicitly listed as unplayable and requiring the original NES ROM to reassemble.
