A Game Boy emulator written in C++ for Windows/Linux. My goal for this project is to learn about Game Boy hardware and emulation and get most Game Boy games playable.
- Video emulation using OpenGL to render graphics
- Sound emulation with SDL2
- Currently supports MBC1, MBC2 and MBC3 (minus real-time clock) cartridge types
- Includes a command line debugger for stepping through instructions, setting break points and viewing memory and register contents
- Keyboard controls (not currently changeable) - arrow keys for d-pad, A, B, enter and backspace for a, b, start and select
- Uses CMake to build
- Depends on OpenGL, SDL2, and Booost program_options
- After compiling run from command line with the filename of the ROM to load as first argument. Use --help or -h to see all commands
