# Caesar II: a portable build of recovered game source

> Caesar II ports recovered source from the 1995 game to Linux, Windows, macOS and browsers through SDL3. It replaces DOS and Windows platform calls while retaining the game's logic, and adds an XMIDI and OPL3 music stack, Smacker playback and an importer for data from the user's copy. The repository also carries tooling for comparing the original executable with a reconstruction.
