| License | The project identifies itself as open-source software under the MIT License. | The repository identifies Fling as MIT licensed. |
| Purpose | ChooChoo is a Proton/WINE trainer and DLL loader for launching games with trainers, mods, patches, and extra executables or DLLs. | Fling UI is a fullscreen, controller-first trainer manager for Steam and Proton on Linux. |
| Security | GitHub's project security page says no security policy is detected and no security advisories are published. | The installer verifies the release archive against SHA256SUMS before extraction, but the project says trainer SHA-256 metadata is diagnostic and does not prove a trainer is safe. |
Plans
In their own words
ChooChoo Loader
ChooChoo Loader launches games through Proton or WINE alongside trainers, mods, patches, or other executables and DLLs. It can start a game and another program together, and supports up to five additional executables or DLLs. Before injecting a DLL, it checks whether its 32-bit or 64-bit architecture matches. Users can save and load profiles, have the last-used profile open automatically after a configurable delay, and reselect recently used game or trainer executables. The v5.0 release describes a touch-first interface with larger controls for touch and mouse input. The project README describes use with Steam and Proton on Steam Deck, and with Whisky on macOS; it cautions that Whisky is unsuitable for this style of gaming when binaries require complex memory manipulation. ChooChoo Loader lists Linux, macOS, web, and Windows. It is free, open-source software under the MIT License. The project directs users who find a bug to report it but does not specify a support service.
