CheatDeck vs GameBuff

CheatDeck is a free, GPL-3.0 Decky Loader plugin for Steam Deck that launches sidecar programs and manages game launch options. It can start a selected .exe or .bat alongside a game in the same Proton or Wine environment, then stop it when the game exits. Its Language setting assigns one locale code to both LANG and HOST_LC_ALL. Advanced controls cover desktop behavior, FSYNC, WineD3D, compatibility-data redirection, and audio latency. Custom Options accept environment assignments, prefix commands, and arguments before or after %command%. Unsupported shell syntax or unclear launch options make a document read-only to prevent unsafe partial edits. Optional Lossless Scaling and OptiScaler presets require their corresponding Decky plugins. Installation uses Decky Loader Developer Mode and CheatDeck.zip from a release or nightly build. Some sidecars need runtime dependencies installed with protontricks.

GameBuff is a Windows game trainer for changing aspects of single-player games. The maker describes its library as covering more than 7,000 games, while its game library page lists more than 2,000 trainers and two modification modes. Advertised one-click changes include god mode and unlimited resources. The homepage names Steam, Epic, GOG, Xbox, and Ubisoft among the game platforms associated with its offering. GameBuff fully supports 64-bit Windows 10 and 11, has limited Windows 7 compatibility, and does not support macOS or cloud gaming platforms. It is intended for local PC hardware and single-player games or local single-player modes; features are disabled in competitive online matchmaking. Real-time memory changes end when the trainer closes or the game restarts, although changes saved to local save data may persist. The client download is free, and trainers can be browsed without an account. An account is required to activate trainer features and use cloud configuration sync or GamePP remote control. The maker warns that security software may flag the installer or trainer behavior because trainers use memory injection.
