The Windows build of Camilo DelCódigo’s engine reimplementation of the original 1981 Apple II Ultima. Requires Windows 10 or later.
The Linux build of Camilo DelCódigo’s engine reimplementation of the original 1981 Apple II Ultima.
Open Sosaria is a from-scratch engine that allows the original Ultima (1981) for the Apple II to be played on modern PCs. California Pacific Computer Company first published that game, and it later became Ultima I: The First Age of Darkness. This new engine is written in C, as opposed to any flavour of BASIC. It doesn’t include any of the original game’s files, manuals or disk images; like many other such projects, it reads the player’s own Apple II game data.
Since version 0.5.0, the game can be played all the way through, from character creation to the final fight with Mondain. Version 0.6.0 added sound to every scene, recreating the Apple II’s single click-based speaker, along with an option to steal in towns. Ready-made builds are available for Windows and Linux. Mac OS users can build it from the source code.
As of November 2026, the latest release on GitHub is v0.6.0 (August 2026).
