What GBA Emulator is

GBA Emulator is a free Game Boy Advance emulator written in C with an SDL2 frontend for Linux, macOS and Windows. The project targets Pokémon Emerald, described as playable from beginning to end. It supports ARM and Thumb instructions, graphics modes, sprites, scanline rendering, stereo audio at 32768 Hz, DMA, timers, interrupts and flash saves. Pressing F2 opens Hardware X-Ray, a second window showing graphics layers, tiles, palettes, CPU state, audio and other system details; the project says this adds no overhead when disabled. Ten numbered save-state slots include versioning and ROM-hash checks. Rewind covers the previous 60 seconds and stores compressed snapshots in RAM, capped at 256 MB. Cheats include GameShark, Action Replay v1–v3 and CodeBreaker codes loaded from a .cht file. Two local instances can connect for two-player 16-bit multiplayer, but internet netplay is unavailable. Users must supply their own BIOS and ROM files.
