Summary
Retra is a free Android Game Boy Advance emulator, patch workspace, save vault, and personal game archive. It uses a native mGBA libretro core and organizes games in grid or list views, with search and filters for favorites, patches, homebrew, and unplayed titles. It can import .gba, .zip, .ups, .ips, and .bps files, apply UPS, IPS, and BPS patches to compatible user-provided base files, and rejects Nintendo DS .nds files. Save features include local saves, automatic backups, a timeline, save health information, screenshots, and rewind. Controls include touch, keyboard, and gamepad, with analog and dead-zone calibration and Controller Studio. The product overview says ROMs, battery saves, save states, screenshots, and settings stay on the device; Google account linking is optional for identity personalization. A fresh install imports Retra Drift, an original 64 KiB GBA homebrew mini-game. Commercial ROMs are not included, and users must provide compatible backups they are entitled to use. The listed Android APK releases are personal or open-source sideload test builds, not Play Store releases.
