An NES emulator written in C++ for nothing but fun.

Examples of games that have been tested to run (but NOT limited to):

(USA/Japan or World versions only i.e. NTSC compatible)

* Super Mario Bros.

* Contra

* Adventure Island

* Ninja Gaiden

* Wrecking Crew

* Megaman and Megaman 2

* Mario Bros.

* Donky Kong and Donkey Kong Jr.

Compiling

-----------

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

```

Running

-----------------

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

```
