Install

Get Game

Downloads come from Decomp Buddy's own copy - the same files the app installs, scanned for malware. Most games still need your own copy of the original game to play, and the app sets that up for you.

The Project

Decomp Buddy never hosts or downloads the original game. It sets up COGBox and tells you exactly which file of yours to drop in - then checks it's the right one. A ready-made plan is published for this one, so no AI key is needed. This is a community project: we check it, but we can't guarantee it.
