QuestPatcher is a GUI based mod installer for any il2cpp unity app on the Oculus Quest that runs on Windows or Linux. It was originally created for modding Gorilla Tag.
It uses Sc2ad's QuestLoader for loading mods and is based mostly on RedBrumbler's CLI Tool.
See QuestPatcher.Core/Resources/qmod.schema.json for the mod.json that QMODs must contain, alongside their mod files.
