- iOS (Jailbreak): Cydia. You can open rom files from other apps like Safari or Dropbox. They can be placed in
/var/mobile/Media/ROMs/GAMEBOYtoo. Save files are placed in
- iOS: Build Gearboy with Xcode and transfer it to your device. You can open rom files from other apps like Safari or Dropbox, or use iTunes file sharing.
- Mac OS X:
brew install homebrew/games/gearboy
- Windows: Gearboy-1.6-Windows.zip (NOTE: You may need to install the Microsoft Visual C++ Redistributable)
- Linux: [Gearboy-1.6-Linux.tar.gz](http://www.geardome.com/files/gearboy/Gearboy-0.8-Linux.tar.
- Raspberry Pi: Build Gearboy from sources. Optimized projects are provided for Raspberry Pi 1 and 2/3.
- Highly accurate CPU emulation, passes cpu_instrs.gb from blargg's tests.
- Accurate instruction timing, passes instr_timing.gb from blargg's tests.
- Memory Bank Controllers (MBC1, MBC2, MBC3 with RTC, MBC5), ROM + RAM and multicart cartridges.
- Accurate LCD controller emulation. Background, window and sprites, with correct timings and priorities.
- Mix frames: Mimics the LCD ghosting effect seen in the original Game Boy.
- Sound emulation using SDL Audio and Gb_Snd_Emu library.
- Game Boy Color support.
- Integrated disassembler. It can dump the full disassembled memory to a text file or access it in real time.
- Saves battery powered RAM cartridges to file.
- Compressed rom support (ZIP deflate).
- Multi platform. Runs on Windows, Linux, Mac OS X, Raspberry Pi and iOS.
- Install Xcode for Mac OS X. You need iOS SDK 8 or later.
- Build the project.
- Run it on real hardware using your iOS developer certificate. Make sure it compiles on Release for extra optimizations.
- For jailbroken devices use the jailbreak branch.
Raspberry Pi 2 & 3 - Raspbian
- Install and configure SDL 2 for development:
sudo apt-get update sudo apt-get upgrade sudo apt-get install build-essential libfreeimage-dev libopenal-dev libpango1.0-dev libsndfile-dev libudev-dev libasound2-dev libjpeg-dev libtiff5-dev libwebp-dev automake cd ~ wget https://www.libsdl.org/release/SDL2-2.0.4.tar.gz tar zxvf SDL2-2.0.4.tar.gz cd SDL2-2.0.4 && mkdir build && cd build ../configure --disable-pulseaudio --disable-esd --disable-video-mir --disable-video-wayland --disable-video-x11 --disable-video-opengl --host=armv7l-raspberry-linux-gnueabihf make -j 4 sudo make install
- Install libconfig library dependencies for development:
sudo apt-get install libconfig++-dev.
make -j 4in the
platforms/raspberrypi2/Gearboy/folder to build the project.
export SDL_AUDIODRIVER=ALSAbefore running the emulator for the best performance.
- The emulator generates a
gearboy.cfgconfiguration for you where you can customize keyboard and gamepads. Key codes are from SDL.
- You need Visual Studio 2010 or better.
- Install the Qt 5 SDK for Windows.
- Install the Qt 5 Visual Studio Add-in and point it to the Qt SDK.
- Install and configure SDL 2 for development.
- In order to use OpenGL extensions I used GLEW. This is because of a bug in QGLFunctions. Make sure the GLEW headers and libs are configured within VC++.
- Open the Gearboy Visual Studio project and build.
Mac OS X
- You need Qt Creator, included in the Qt 5 SDK.
- Install Xcode and run
xcode-select --installin the terminal for the compiler to be available on the command line.
- Install the Qt 5 SDK for Mac OS.
- Download SDL 2 source code. Then run this commands:
./configure make sudo make install
- Open the Gearboy Qt project with Qt Creator and build.
- Install Qt 5 development dependencies (Ubuntu:
sudo apt-get install qt5-default qttools5-dev-tools).
- Install OpenGL development dependencies (Ubuntu:
sudo apt-get install freeglut3-dev).
- Install SDL 2 development dependencies (Ubuntu:
sudo apt-get install libsdl2-dev).
- In order to use OpenGL extensions I used GLEW dependencies (Ubuntu:
sudo apt-get install libglew-dev). This is because of a bug in QGLFunctions.
- Move to the
platforms/linux/Gearboy/folder and run
qmake -o Makefile Gearboy.pro && maketo build the project.
- In Ubuntu I had to
export SDL_AUDIODRIVER=ALSAbefore running the emulator for the sound to work properly.
