Implemented a tailored version of the 6502 microprocessor architecture for emulating the Nintendo Entertainment System in C++. Note- Roughly 40-50% of games should work (ie. games that use either no mapper or mappers 1, 2, 3 and experimental support for 4, 7, 66 and 11).
You need:
- SFML 2.0+ development headers and library
- C++11 compliant compiler
- CMake build system
Compiling is straight forward with cmake, just run cmake on the project directory with CMAKE_BUILD_TYPE=Release and you'll get Makefile or equivalent for your platform, with which you can compile the emulator
For e.g., on Linux/OS X/FreeBSD:
$ git clone https://github.com/amhndu/SimpleNES
$ cd SimpleNES
$ mkdir build/ && cd build/
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ make -j4 #Replace 4 with however many cores you have to spare
Just pass the path to a .nes image like
$ ./SimpleNES ~/Games/SuperMarioBros.nes
To set size of the window,
$ ./SimpleNES -w 600 ~/Games/Contra.nes
For supported command line options, try
$ ./SimpleNES -h
