# SkyRoads: a DOS game engine reconstructed in portable C11

> skyroads-port reconstructs the DOS game SkyRoads as a portable C11 engine after disassembling SKYROADS.EXE and documenting its file formats and algorithms. It reads original data files supplied by the user, and the author reports that replaying DEMO.REC follows the original demo road tick for tick.
