SimpleNES

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

Currently WIP.

Only games with atmost 2 program banks, 1 character banks and no "mapper" are supported.
Only one controller is setup at the moment.

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.
• Wrecking Crew
• Ice Climber
• Mario Bros.
• Donky Kong
• Donkey Kong Jr.
• Arkanoid
• Balloon Fight
• Tennis
• Elevator Action
• Excitebike

Here's a big list of games that match the supported specs from SimpleNES.
(Unlike the list above, these aren't tested. Some may or may not work)

Executables:

Windows 32-bit
Linux 64-bit

ROMs available here for testing.

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/super_mario_bros.nes

For supported command line options, try

$ ./SimpleNES -h

Controller

These keybindings are hard-coded (for Player 1)

Button	Mapped to
Start	Return/Enter
Select	Right Shift
A	J
B	K
Up	W
Down	S
Left	A
Right	D
