Thanks for that, Akari. That adds to my notes nicely. Still a lot of unknowns. Here's a few more things:
Some codes share implementations:
9A & FB
B2 & C9 (B2 isn't a loop pointer though. I haven't found any indication that it's used)
BB, C0, CD, D2, D3, D9 & EF all run the same code that any value less than 8E would run as if they were animations.
EE & FF
I think Christopher's script might prove enlightening, too.
