Dino the Dark Dragon began reverse-engineering the Ultima 1 engine as a spare-time project in 2007. Initially, he managed to produce a basic engine for the game, as well as some documentation about the files and sites.

A spare-time project, Ultima 1 Revenge saw a few different iterations. The first version of the engine was written in C and used the SDL libraries. A second, XNA-based version allowed Dino to make significant progress on the project; two demos were released, and he was also able to develop numerous tools. However, the use of XNA limited him to the Windows platform (XNA could not be cross-complied to other systems), and support for the language was later dropped by Microsoft.

The current — third — version of Ultima 1 Revenge is being built with C++ and SDL2. Dino’s aim for the project, now, is to build tools that will work with the original Ultima 1 game files, and (ultimately) to create a cross-platform engine for Ultima 1 in the spirit of Exult.
