## What it is
NanoBoyAdvance is a cycle-accurate Nintendo Game Boy Advance emulator written in C++ with a Qt-based GUI. It prioritizes hardware accuracy, passing AGS aging cartridge, ARMWrestler, and mGBA test suites, while offering enhancements like HQ audio mixing, xBRZ upscaling, and LCD ghosting simulation.

## Use cases
- play game boy advance games on pc
- cycle-accurate gba emulator
- emulate gba games with high accuracy
- run gba roms on linux mac windows
- gba emulator with save states and controller support
- emulate boktai solar sensor
- debug gba ppu tiles and sprites

## When to choose
- you need maximum accuracy for GBA games, including edge cases like Game Pak prefetch and DMA timing
- you want enhancements such as improved audio, color correction, and upscaling filters
- you need debugging tools like PPU palette, tile, and sprite viewers
- you want RTC or Solar Sensor emulation for games like Boktai

## When to avoid
- you want a lightweight, low-spec emulator for weak hardware
- you need netplay or online multiplayer features
- you prefer a simple plug-and-play emulator without needing a BIOS file
- you want emulation of other consoles beyond the GBA
