Running

Download a recent development build or the last stable release.

Upon loading a ROM for the first time you will be prompted to assign the Game Boy Advance BIOS file.
You can dump it from a real console (accurate) or use an unofficial BIOS (less accurate).

Accuracy

A lot of research and attention to detail has been put into developing this core and making it accurate.

• Cycle-accurate emulation of most components, including: CPU, DMA, timers, PPU and Game Pak prefetch
• Passes all AGS aging cartridge tests (NBA was the first public emulator to achieve this)
• Passes most tests in the mGBA test suite
• Passes ARMWrestler, gba-suite and FuzzARM CPU tests
• Very high compatibility, including games that require emulation of peculiar hardware edge-cases
