NanoBoyAdvance

NanoBoyAdvance is a highly accurate Nintendo Game Boy Advance (TM) emulator.
It is also intended to be reasonably efficient, bloat-free and clean code in modern C++.

You can download nightly builds here, however a Github account is required.
For stable releases please refer to the releases page.

Running

A legitimate Game Boy Advance BIOS dump or a replacement BIOS is required.
Do note though that the replacement BIOS is less accurate.

Place your BIOS file named as

bios.bin

CLI arguments

NanoboyAdvance.exe [--bios bios_path] [--force-rtc] [--save-type type] [--fullscreen] [--scale factor] [--resampler type] [--sync-to-audio yes/no] rom_path

See config.toml for more documentation or options.
