NanoBoyAdvance Git (2026/05/09) is a Nintendo Game Boy Advance emulator developed in C++17, aiming for a minimal and accurate performance. The emulator effectively replicates core hardware, allowing nearly all games to run without issues, including those with complex edge cases. Recent updates include transitioning to C++ 20, upgrading to Qt 6, and fixing a README footnote. Users need a BIOS file, which can be either dumped from their device or sourced from an open repository. The BIOS must be named bios.bin and placed in the same folder as the emulator executable. Download options are available online.

NanoBoyAdvance Git (2026/05/09) has been compiled. NanoboyAdvance is an emulator for the Nintendo Game Boy Advance (TM) developed using C++17. The aim is to build a minimal, precise, and reasonably efficient emulator for the Game Boy Advance in modern C++. This emulator accurately implements the core hardware and achieves high precision. Almost all games can be emulated without known issues, including ‘Classic NES’ titles that exploit various edge cases and undefined behaviors.
Nanoboyadvance Git changelog:
* README: repaired broken footnote
* Code cleanup and transition to C++ 20, upgraded builds to Qt 6, copyright update (#420)
Running
To run NanoboyAdvance, you will need a BIOS file. You can either dump your own or find an open-source alternative online (https://github.com/Nebuleon/ReGBA/blob/master/bios/gba_bios.bin). The BIOS file should be named bios.bin and placed in the same directory as the executable. However, be aware that a replacement BIOS may not match the accuracy of the original.
