Yet another yet another Chip-8 emulator (yayacemu)

Because one just wasn't enough.

A Chip-8 emulator (interpreter) written in SystemVerilog with I/O simulated with C++ also depends on SDL2.

Building & Testing

In order to run yayacemu, you must have sdl2, verilator, and make installed.

Once you have the dependencies installed, you can build the emulator with:

make build

You can build start the emulator with:

make run ROM_FILE=[PATH_TO_YOUR_ROM]

Running

If you have a binary, you can run it with the following:

yayacemu [PATH_TO_YOUR_ROM]
