NanoBoyAdvance

NanoBoyAdvance is a Game Boy Advance emulator with a focus on high accuracy.

Features

• highly-accurate GBA emulation
• HQ audio mixer (for titles which use the Sappy/MP2K/M4A sound engine)
• RTC emulation
• game controller support
• GLSL shader support

Accuracy

• close to cycle-accurate CPU and DMA emulation
• hardware is updated at the bus cycle (sub-instruction) level
• very accurate ARM emulation
• PPU is still scanline based for now

See ACCURACY.md for more information on which tests NanoBoyAdvance passes and fails.
