In the first code example in the readme ("First program"), there's `sdlcls`, `SDLinit`, and `SDLShow`. Is there some significance to the capitalisation?
Ah, it might be nice to mention that before the first code example, then. Or just use consistent case in the first example, to avoid distracting people with details that aren't the thing you're trying to demonstrate.
Very interesting, great work! This reminded me of something. I just checked and to my amazement Mike Hore's Powermops is still around and even has an ARM version.[1]
