What it does
Features
Three sources
Homebrew Hub (1,600+ Game Boy, GBC, GBA and NES homebrew), free itch.io homebrew, and ~675 ready-to-run PortMaster ports.
Checks before it installs
Badges show whether your device can run a game. After downloading, the ROM header is checked, so broken files and PC builds are never installed.
Installs the muOS way
Games go into the ROM folders muOS already uses, with box art and a description. PortMaster ports are installed with PortMaster itself.
Try it
Start a game straight from the app, then mark whether it works.
My games
Every game on your SD card by system, with play time, favourites, box art, start and uninstall.
Sort, filter and ratings
Newest, top rated or A to Z; filter by genre; star ratings and a screenshot gallery for each game.

How to install
- Download GameManager-1.0.0.muxapp.
- Copy it to the
ARCHIVEfolder on SD card 1 (create the folder if it doesn't exist). - On the handheld, open Applications → Archive Manager and install it.
- Turn on Wi-Fi, then open Applications → Game Manager.
Downloading from itch.io needs your own free itch.io API key (create one here). Add it in the app under START → Settings. Homebrew Hub and PortMaster work without an account.

Where the games come from
Game Manager downloads games from Homebrew Hub, itch.io and PortMaster, and box art for your own games from the libretro thumbnail library. Nothing is hosted by PocketKode: files come straight from those services when you ask for them. The games belong to their creators; check each game's license. Game Manager is an independent app, not affiliated with any of these services, muOS or Anbernic.
