# OpenSWE1R: porting Star Wars: Episode I Racer with runtime code replacement

> OpenSWE1R ports the Windows x86 release of Star Wars: Episode I Racer by patching replacement open-source code into the game at runtime. It combines x86 CPU emulation with implementations of the Windows functions the game uses. Unreplaced functions still execute from the original game binary, and game art comes from the user's copy.
