PatchForge

A video game binary patch and installer generator that produces self-contained Windows executables. Three modes:

• Update Patch — diff an old and new copy of a game directory and produce a standalone patcher .exe users double-click to update their install
• Repack — compress a complete game directory into a standalone installer .exe users double-click to install the game from scratch
• Archive — log into Steam, watch one or more appids, download every new build to a 7z archive, optionally crack + upload + post — fully automated mirroring of game updates

---
