    Bumbershoot is a great blog if you are a 1980s home computer/console enjoyer, but were never quite sure how it all worked. He is trying to figure this out himself, so he goes step-by-step through getting his games working on a particular system.

    So there are a lot of ASM 'deep dives' like this entry (which probably won't get too much traction.) My one complaint is he has a lot of content, but the blog is hard to navigate.

    This was a tough but fun read. It's my understanding that the three restrictions ensure, by way of overshooting, that there's no need to do any expensive if-tests. Everything can just go full throttle.
