The best free homebrew games for the Anbernic RG40XXH (muOS)
Your Anbernic RG40XXH doesn’t need pirated ROMs to be fun. People are still making new games for old consoles (Game Boy, Game Boy Color, GBA, NES) and releasing them for free. There are also free PC games ported to handhelds through PortMaster. Everything on this list is free, shared by its creators, and legal to download.
How we picked: games from Homebrew Hub, itch.io and PortMaster, the same sources Game Manager uses. Ratings are the player ratings on each game’s itch.io page (as of September 2026). We only counted games with at least 10 ratings, and we left out demos, unfinished betas and fan games that use other companies’ characters.

How to get them on your handheld
The easy way: Game Manager. It’s a free muOS app (made by us) that browses Homebrew Hub, itch.io and PortMaster with the controller. Open a system, go to Top rated or Search, and install. It checks that each game will run on your device, puts it in the right ROMS folder with box art, and installs PortMaster ports with PortMaster’s own installer.
By hand:
- Download the ROM from the game’s page. On itch.io, choose the file for the right system (
.gb,.gbc,.gbaor.nes). Many pages also offer PC versions. - Copy it to the matching folder on SD card 1:
ROMS/GB,ROMS/GBC,ROMS/GBAorROMS/NES. Use a card reader or Wi-Fi Transfer, which sorts ROMS into the right folder automatically. - On the handheld, go back to the main menu, open Explore Content and pick the system.
For PortMaster games, open the PortMaster app on the handheld (it’s in Applications) and install them from there.
Support the developers
All of these games are free, and many developers accept an optional payment on itch.io. If you enjoy one, leave a rating or a comment on its page, or tip them if you can. That’s what keeps new homebrew coming.
