GAME BOY COLOR EMULATOR
Azayaka
Azayaka is an open-source, cycle-accurate Game Boy (DMG) and Game Boy Color (CGB) emulator written in C++ with features like rewind, save states, audio recording, a console debugger, RTC support, and automated testing.

WHY IT MATTERS
Why this project matters
Azayaka focuses on cycle-accurate Game Boy / Game Boy Color emulation and includes developer-friendly features (console debugger, disassembler, automated tests) plus user features (rewind, save states, audio recording). It aims at high accuracy (passes most community accuracy test suites) while remaining a single-repo C++ project that can be built on Unix-like systems.
BEST FOR
Notable strengths
Cycle-accurate implementation; integrated test harness (blargg and Mooneye test results referenced in the repo); developer tooling (disassembler, console debugger, automated testing); rewind implementation and audio recording support.

History & status
The repository identifies Zach Collins as the author and copyrights the project 2020–2021. The README describes 38 commits and repository activity; the project is available on GitHub under the GPL-3.0 license. The repo advertises feature and test coverage (passes all blargg tests except oam_bug and passes most of Mooneye's Mooneye GB tests). Prebuilt releases are not published in the repository's Releases section; the README contains build and run instructions for Unix-like systems and notes Windows support as "Coming soon!".

Setup note: Azayaka is distributed as source code on GitHub. The primary supported platforms are Linux and macOS; Windows support is listed as forthcoming. The project uses CMake and depends on SDL2, libpng (optional for PNG screenshots), and OpenGL (optional for hardware-accelerated rendering). Below are practical, repository-specific steps to build and run Azayaka-SDL on a Unix-like system.
- 1) Get the source: Clone the official repository (git clone https://github.com/7thSamurai/Azayaka). Use the master branch unless you have a reason to use a different tag or commit.
- 2) Install build dependencies: Install CMake, a C++ compiler (g++ or clang), SDL2 development headers, libpng (optional; otherwise BMP screenshots are used), and an OpenGL development stack if you want hardware-accelerated rendering. On Debian/Ubuntu: sudo apt update && sudo apt install build-essential cmake libsdl2-dev libpng-dev libglu1-mesa-dev mesa-common-dev. On macOS with Homebrew: brew install cmake sdl2 libpng.
- 3) Configure and build: From the repository root: mkdir build && cd build && cmake .. && make. This produces Azayaka-SDL (the SDL frontend) and Azayaka-tester (the test runner) as described in the README.
- 4) Running the emulator: Run the SDL frontend: ./Azayaka-SDL [ROM or directory path] [options]. Common options documented in the repo include -g/–force-gb to force DMG mode, -c/–force-gbc for Color mode, -l/–link to enable link cable support, and -p/–printer to enable Game Boy Printer emulation. The emulator maps keys by default (A=Z, B=X, Start=Enter, Select=Space) and supports save states (F1–F10 and Ctrl+F1–F10) and rewind (Backspace).
- 5) Developer & testing tools: Azayaka includes Azayaka-tester to run test ROM suites (the README references blargg and Mooneye tests). The repo also contains a console-based debugger, a disassembler with code/data logging, and an automated testing system—use these tools from the build outputs for debugging or verification.
- 6) Platform notes & binaries: The README lists Linux and macOS as supported platforms. The Releases page in this repository shows no published releases, and the README states Windows support is coming. If you need a binary for Windows you will currently need to build from source on a Windows environment or use a community fork if available; check the repository for any platform-specific build notes or CI artifacts.
- 7) Runtime files and legality: Azayaka does not include commercial games, firmware, or BIOS files. Use only ROMs and BIOS/Firmware you legally own. The README does not mention any requirement for a separate BIOS to run Game Boy or Game Boy Color games.
Software reminder: Build from source using the repository's instructions; prebuilt releases are not present in the repo. Follow the GPL-3.0 license included with the project.
