I now have a working Game Boy character controller where the D-pad causes a little box to move freely around the screen. That's not really something I needed, but it's now something I have.

As you perhaps can see above, I'm developing this in my own macro language, which theoretically means when I move to the next bit I can introduce high-level abstractions, but only if I change the language to add macros. I need to learn what a "quasiquote" is I guess.

A box, inside of which is a small box with an X in it, running in the "Mesen" emulator.
