What NanoBoyAdvance is

NanoBoyAdvance is a free, open-source desktop emulator for Game Boy Advance games, available for Linux, macOS, and Windows. It emulates components such as the CPU, DMA, timers, PPU, and Game Pak prefetch cycle by cycle. The project says it passes all AGS aging cartridge tests and most tests in the mGBA test suite. Visual options include color correction, xBRZ upscaling, and LCD ghosting simulation, while its audio mixer supports games using Nintendo’s MusicPlayer2000 sound engine. Users can remap controller buttons and axes, load ROMs from ZIP, 7z, or tar archives, and store progress in 10 save-state slots. It also supports RTC and Solar Sensor emulation, including for Boktai - The Sun is in Your Hand. Debug tools include viewers for PPU palettes, tiles, backgrounds, and sprites. On the first ROM load, the emulator asks the user to assign a Game Boy Advance BIOS file. The project is licensed under GPL 3.0 or later; its GitHub repository was archived on June 21, 2026, and development is stated to continue on Codeberg.
