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

Roughly 40-50% of games should work (ie. games that use either no mapper or mappers 1, 2 ,3 ,4 (BUG),7 & 66 partial 11).

Added APU experimental works with the sdl2 library in linux i have encountered a problem with apu enabled only the debug mode works and few games crash.

the build release gives a black screen maybe there is a bug in the apu.

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.
• Battle City
• Paperboy
• Legend of Zelda
• Pacman
• Tennis
• Excitebike
• Nightmare Elm Street
• Cabal
• Battletoads
• Battletoads & Double Dragon

Executables:

Windows 32-bit Linux 64-bit

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

Keybindings can be configured with keybindings.conf

Default keybindings:

Player 1

Player 2
