RomBoy: Retro Game Emulator

RomBoy is a retro game emulator for Android with built-in Game Boy, Game Boy Color and Game Boy Advance support. Bring your own compatible games, choose a skin and play with touch controls or a compatible controller.

Play offline
Import compatible ROM files from your phone, or download games from your own RomM library. Once stored on your phone, games are ready to play offline. A server is optional: local imports work independently.

Keep your collection close
• Find your games with cover artwork, search and recently played titles.
• Keep your latest game close at hand on Home.
• Browse a connected RomM library and choose what to download.
• Pause, resume or retry server downloads.
• Remove a downloaded game from your phone while keeping its saves and the original on your server.

Keep your progress
• Save your progress on your device.
• Import and export save files from a game's page.
• Back up saves automatically for games linked to a connected RomM library.
• Review conflicting saves and choose which version to use.

Server browsing, downloads and backups require a compatible RomM server. Backups also require a connection and the necessary save support on that server.

Make it your RomBoy
• Play using touchscreen controls or a compatible controller.
• Choose customisable gameplay skins.
• Play in portrait or landscape.
• Switch the app to dark mode.

Dual-screen compatibility
Compatible with supported Android dual-screen devices, including AYN Thor. Use both built-in screens with a companion dashboard, and move gameplay between the top and bottom screens.

Supported now
Game Boy (GB), Game Boy Color (GBC) and Game Boy Advance (GBA).

Sega Mega Drive and Nintendo DS are future plans. They are not included in the current app, and release dates are not set, but both are expected before 2027.
