There are no further updates for this project. I did this more of a proof-of-concept, or a test of my own abilities to see if it was possible to combine program, character glyps, sprites, color and palette ROMs all into 1024 bytes of space. I was curious as to how the constraints would play out, and really just what it would be like to work within those constraints.

It's a pretty interesting idea, and I'm not really sure there's anywhere to go with it from here. 512ish bytes of program space is a bit too limiting for me. I could probably crunch my code down another 100 bytes by dropping some of the input routine checks and niceties, but I've proven to myself that I can do it, and it's time to move on... ;)
