CheatDeck vs LaLa Trainers Launcher

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.

LaLa Trainers Launcher is a free launcher for discovering, managing, and running game trainers. It supports Linux and Windows. Windows users install the provided executable. Linux and Steam Deck downloads offer AppImage, Flatpak, binary, and Debian or Ubuntu package options. On Linux, LaLa uses Proton to run trainers, so the game must already be installed and configured to use Proton. The project says its trainers come from Fling Trainers and warns that trainer use can carry risks. A listed release feature allows custom trainers. For Linux game-detection problems, the project advises checking Proton setup, starting the game before the trainer, or trying another trainer version. The Flatpak build is not supported in Steam Deck gaming mode. LaLa is open-source Flutter software under the AGPL-3.0 license. The maker also accepts support through Ko-fi.
