CoSMOS vs TrainerBridge

CoSMOS is a free self-service gamehacking tool for people who want to modify their own games while waiting for trainers. It is offered in Steam Deck, PC Beginner, and PC Advanced versions, with options for beginners and experienced gamehackers. The Steam Deck edition is a native application for Linux and Steam Deck, with a simplified memory scanner and built-in disassembler. PC Beginner is integrated with Cheat Happens Aurora. PC Advanced includes a memory scanner, VEH debugger, script engine, disassembler, dump viewer, speedhack, .NET assembly explorer, reference search, process viewers, and script editor; its listed version is 6.1.5. CoSMOS uses hardware-accelerated scans and can read and import 99% of CheatEngine tables. The free tool requires no registration, has no locked features, and includes no adware or hidden software. Cheat Happens provides technical support through its message board. The maker advises using cheats and trainers offline only and says it does not make cheats for online or multiplayer games.

TrainerBridge is a free, open-source Linux application for running standalone Windows trainers with Steam games through Proton. It examines Steam libraries, identifies each game’s Proton version and compatdata prefix, then starts a trainer inside the matching Proton environment. You can import and manage one trainer executable for each Steam game and launch the game and trainer together or independently. Steam installations delivered as native packages, Snap, or Flatpak are supported. An optional Protontricks frontend can place common runtimes, fonts, settings, and applications into a game prefix. Before prefix changes, TrainerBridge can create backups using copy-on-write folders on compatible Btrfs filesystems or compressed .tar.zst archives elsewhere. Downloads include an x86_64 AppImage and portable .tar.xz archive with SHA-256 checksums. It does not supply trainers, alter game files, or bypass anti-cheat systems. Prefix component compatibility varies by game, prefix state, Proton version, and Winetricks recipe.
