An NES emulator written in C++ for nothing but fun.
Roughly 50-60% 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).
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
- Arch Rivals
- etc...
You need:
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
See also: compile.yaml for platform specific instructions
- Download an executable based on your platform from the latest run on Github Actions
- Install sfml
- Windows:
vcpkg install sfml. Alterntaively, download from SFML - Debian/Ubuntu/derivates:
sudo apt install -y libsfml-dev - Arch/etc:
sudo pacman -S sfml - MacOS:
brew install sfml
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
