Why?

I had fun building my CHIP-8 emulator using Zig and now I'm attempting the Game Boy. Of course, it's also an excuse to learn Zig! Apart from minor dabbling with C++ in college, Zig is my introduction to a lower level, "systems" language. A desire to get more comfortable with this space!

Run

Ensure SDL libraries are installed. For MacOS:

brew install sdl2

Then:

zig build run
