What it does
Homebrew Hub (free Game Boy, GBC, GBA and NES homebrew), free itch.io homebrew, and ready-to-run PortMaster ports.
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.
Games go into the ROM folders muOS already uses, with box art and a description. PortMaster ports are installed with PortMaster itself.
Start a game straight from the app, then mark whether it works.
Every game on your SD card by system, with play time, favourites, box art, start and uninstall.
Newest, top rated or A to Z; filter by genre; star ratings and a screenshot gallery for each game.

Install
ARCHIVE folder on SD card 1 (create the folder if it doesn't exist).Roms/APPS folder (Game_Manager.sh, the GameManager folder and Imgs) into Roms/APPS on SD card 1, with a card reader or over Wi-Fi (Samba or SFTP).On the stock OS, the games you install appear in each system's game list in the main menu, and you can also start them from My games. For PortMaster ports, Game Manager installs the latest PortMaster the first time (the one Anbernic's stock OS includes is too old for today's ports); ports then appear in the stock menu's PORTS list.

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.
Guide
The basics, from your first game to a tidy SD card.
Y sorts and filters, X searches. READY means a game runs on your handheld; NO EMU means it doesn’t.
Every file is checked before it’s installed, so broken files and PC-only builds never reach your SD card.
itch.io downloads need a free API key. You only set it up once.
Every game on your SD cards, sorted by system, including the ones you added yourself.
Uninstalling never deletes your saves.
Hold SELECT + START for 2 seconds. This works for games you start from Game Manager.
When a new version is out, Update available appears on the home screen. Press A to update; your games and settings stay.
logs/app.log from the app’s folder.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.
