GBAxJS brings a GBAx interface to browser play. Open a game from your device, use keyboard, supported controllers or touch controls, and expand the player when you want more room.
Your Library and Progress
My Library brings favourites, recent games and save backups together in this browser. Local game files are not uploaded. This is local storage, not an account or cloud-sync service: keep downloaded backups and test a restore before relying on them.
A Preview Built Around Feedback
Mobile resume, orientation changes and expanded-view transitions remain priorities for device testing. Browser and OS versions affect behaviour. Report the exact steps when something fails; never attach your game file.
