What GBA Emulator is
GBA Emulator is a free Game Boy Advance emulator written from scratch in C with an SDL2 frontend for Linux, macOS, and Windows. The project targets Pokémon Emerald, which it describes as fully playable end-to-end. It supports ARM and Thumb instructions, graphics modes, sprites, audio, DMA, timers, interrupts, and flash saves, with scanline graphics rendering and 32768 Hz stereo audio through SDL2. Pressing F2 opens Hardware X-Ray, a second window showing graphics layers, tiles, palettes, CPU state, audio, DMA, timers, and interrupts; the project says this adds no overhead when disabled. Ten numbered save-state slots include versioning and ROM-hash checks. Rewind covers 60 seconds with a 256 MB RAM cap. Cheat files support GameShark, Action Replay v1–v3, and CodeBreaker. Two local instances can connect for 16-bit multiplayer, but internet netplay is unavailable.
