An NES emulator written in C++. Currently supports NROM and UxROM cartridges.
I mainly wrote this to learn C++. I started working on it around the June of 2022 and it took about 3 months to finish. I was completely new to C++ at the time so you might find some quirky or weird usage of the language in this codebase.
In order to run the emulator you first need:
- SFML
- SDL
Why both SFML and SDL? Frankly, because I didn't know any better. I started with SFML and upon reaching the audio implementation realized it wasn't going to cut it. So I used SDL for audio.
Next you'll also need Bazel. You could, if you want, write a Makefile for this. But if not, you need Bazel.
Finally, you'll need to modify the BUILD.bazels in third_party/ with the locations where you installed SFML and SDL. You'll also need to modify WORKSPACE.bazel for the same reason.
First build the binary.
bazel build src:main --cxxopt='-std=c++20' --copt=-O3It is imperative that the binary is built using O3 optimization as this is required to smoothly run the emulator. But the codebase is small so this shouldn't take too long.
Then, run your game, for example:
./bazel-bin/src/main Contra.nesThat's it! Shoutout and big thanks to the 'NES Development Server' discord community!
