An Open-Source port of the 1999 Game "Star Wars: Episode 1 Racer"

This project is a mix of console emulation and something like WINE. It implements the subset of Windows functions used by the game. OpenSWE1R also contains x86 CPU emulation. The original games code is replaced by open-source code which is patched into the game at runtime. This is similar to the approach used by OpenRCT2, but more emphasis is put on emulation and platform independence.

Currently, not all functions are implemented in the open-source portion. Therefore, this project also still relies on the original games binary. Even if not all code is patched, the game will still work cross-platform due to the API and CPU abstraction.

You will still need the original game for its art assets: levels, sounds, ...


The goal is to eventually replace all of the original code with an open-source equivalent. The code is supposed to be clean, accurate and portable.

It's possible that support for other versions (Mac / Dreamcast / N64) will be added later. For now, the goal is to support the x86 Windows Version of the game.
