A simple Nintendo Switch homebrew app that lists your installed games and lets you quickly view game and mod stats, and toggle LayeredFS mods on/off by renaming romfs / exefs folders inside each title’s Atmosphère contents directory.
OCGM is designed to be lightweight, fast, and easy to use through a clean console-based UI.
- Lists installed applications using
nsListApplicationRecord - Displays a Details page for each title:
- Title Name
- Title ID
- Version
- Mod detection (Enabled / Disabled)
- Total Mod Size
- Total File Count
- Whether ROMFS or EXEFS is there or not
- Toggles LayeredFS mods using a safe same-folder rename method
- Uses cached scanning in the Details view to reduce lag
- Runs in Applet Mode or Title Override
OCGM toggles mods by renaming folders inside:
sdmc:/atmosphere/contents//
romfs → romfs_disabled exefs → exefs_disabled
romfs_disabled → romfs exefs_disabled → exefs
This method does not delete or modify files it only renames folders.
