Chupathingy is a port of the Halo: Combat Evolved decompilation to Windows, macOS, Linux, the Steam Deck, Android and FreeBSD, with builds for several consoles in testing. It began as a fork of OpenCE, an earlier port of the same decompilation also listed here, and has had its own code, releases and community since October 2026.
It plays the campaign, split screen, system link and online games with players on every platform. It plays like the Xbox game, and everything extra is a setting. The project says the decompilation it is built on, and the port it was forked from, were made with heavy use of generative AI.
It never includes or downloads Microsoft’s files: the maps are copied from the player’s own disc image.
How to Set It Up
- Download the build for your system and extract it (on Linux, make the AppImage executable). On Android, also copy the disc image to the phone.
- Start Chupathingy. On Windows, if it warns about an unknown publisher, choose More info, then Run anyway; on a Mac, move it to Applications and allow it once in Privacy & Security.
- Pick your Halo disc image and wait while it copies the maps (about 2 GB).
- The game checks for updates when it starts and asks before installing a signed one.

Debug builds, checksums, signatures
- Debug builds, which stop at the first failed assertion and log it: v0.8.1d-debug
- Commit: 844242abdfb9
- SHA256SUMS lists every download’s SHA-256 (the debug builds’ too), and SHA256SUMS.sig signs it. Each zip and the AppImage has its own signature beside it (.sig).
- updates.json and updates.json.sig: the signed list of update files the self-updaters read (0.8.0 and later).
- The public keys: update_key.h
