NES emulator written in D

dnes

A NES emulator written in D. Very much not finished yet.

Building

Install a D compiler and dub, and then run

dub build

Which should pull in the dependencies for you and compile it. If you didn't install the dmd compiler, you might need to use the --compiler flag.

Usage

Currently it only runs mapper 0 games, and compatibility is limited. Here are some games to try:

• nestest.nes
• Micro Mages
• Balloon Fight
• Donkey Kong
• Super Mario Bros
• Wrecking Crew

To run it, pass the path to the ROM file as the only argument:

./dnes roms/nestest/nestest.nes

Currently only player 1 is supported, and the controls are:

• Z - A
• X - B
• A - Start
• S - Select
• Arrow keys - D-Pad

Tests

The tests run the emulator against the test ROMs provided in the repo. In the project root, just run:

dub test

This should compile and run a seperate executable, dnes-test.exe, which runs all the tests.
