What DeckCheatz is

DeckCheatz is a free, open-source Linux tool for running Windows game trainers on SteamOS and other supported Linux systems. It registers as a Steam Play compatibility tool, allowing Steam to launch it alongside an assigned game. The app matches configured trainers to that game's Proton prefix and starts the selected trainer in the background. The maker targets SteamOS on Steam Deck and also names Bazzite, CachyOS, and NixOS. Example cheats listed include infinite health, infinite ammo, unlocking all items, God Mode, and Super Speed x2. The project describes the app as portable and Flatpak-ready. DeckCheatz is independent of trainer developers and companies, and trainer compatibility is being worked out without official integrations. It is intended for single-player use and solo modding, and the maker asks users to keep it offline. The current app has no in-game overlay. A Decky Loader plugin for selecting and toggling trainers from the Quick Access Menu is planned, as are overlay controls for changing cheats during gameplay. The earlier script-based approach ran Wand inside a game's Steam Play prefix and is being rewritten.
