There is a lot of code that determines whether each tile should have animation drawn for it, which has grown bulky due to a lot of corner cases, and is probably due for some reorganization. Regardless, it turns out you were spot on in your assessment. As mentioned in my reply to Michael, it turns placing a keypress check in my delay loop is enough, which only runs after the main animation loop. I added one more at the start of each iteration of the main animation loop just be extra sure.

Ah, right :-)

I had BPL stuck in my head; I'm actually doing LDA $C000, then BPL to skip ahead if no keypress detected, then if BPL isn't true call the input routine
