FrogGBA is a newly released, heavily optimized GBA emulator based on a fork of TempGBA PSP, offering around a 22% performance boost. With the latest libretro-gpsp improvements, PSP-specific optimizations, and several added features, it delivers smoother gameplay across the board. Pokémon Unbound now runs at 50–55 FPS (fully playable with Frameskip 1), and most GBA games achieve full 100% speed.

Features
