NanoBoyAdvance (NBA) is a free and open-source GBA emulator licensed under the GPU GPL 3.0 license or later. It is primarily focused on accuracy. According to the developer, the goal is to achieve fully cycle-accurate emulation in the future, with support for HQ audio mixer (for games that employ Nintendo's MusicPlayer2000 sound engine), RTC emulation, post-processing options and support for controllers. NBA was the first emulator to pass all AGS aging cartridge tests. NBA emulates CPU/DMA with almost-cycle accuracy, and its ARM emulation handles nearly all known edge cases.
NBA can use an actual console's dumped BIOS or the free alternative not containing copyrighted content, although the latter is less accurate.
