NanoBoyAdvance

NanoBoyAdvance is a cycle-accurate Game Boy Advance emulator.
It aims to be as accurate as possible, while also offering enhancements such as improved audio quality.

Features

• Very high compatibility and accuracy (see Accuracy)
• HQ audio mixer (for games which use Nintendo's MusicPlayer2000 sound engine)
• Post-processing options (color correction, xBRZ upscaling and LCD ghosting simulation)
• Save State support (10x save slots available)
• Game controller support (buttons and axises can be remapped)
• Loading ROMs from archives (Zip, 7z, Tar and limited RAR¹ support)
• RTC emulation
• Solar Sensor emulation (for example: for Boktai - The Sun is in Your Hand)

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 (see mGBA suite comparison for more details)
• Passes ARMWrestler, gba-suite and FuzzARM CPU tests
• Very high compatibility, including games that require emulation of peculiar hardware edge-cases (see Game compatibility)
