What Proton Trainer Launcher is

Proton Trainer Launcher is a free Linux utility for running Windows game trainers with Steam games that use Proton. It can detect a running Steam game or accept its App ID, then match the Proton version used by that game. Listed Proton options include GE-Proton, Proton Experimental, and CachyOS Proton. Users can choose interactive or manual launch modes and add an optional delay. Aurora is listed as tested; WeMod, Plitch, FLiNG Trainers, and other Windows trainers that attach to game processes are untested or expected to work. Setup requires Linux with Steam, Proton or GE-Proton, and a Windows trainer executable. The project instructs users to download or clone the repository, set the trainer path, make a Bash or Fish script executable, and run it after starting a Steam game. The executable path must be absolute and use Linux path format, including for a trainer in a Proton prefix. The repository identifies the project as MIT licensed. It works only with games running under Proton; native Linux games are unsupported, and some anti-cheat protected games may not work.
