Some final code requests (and screenshots)

So for instance if you want to jump to free space at F1/5000, you'd do a B2 00 50 31 (first and last byte of offset are reversed), then put the code there and whatever you removed to make room for the jump, then at the end put a FE command/byte (returns to previous code) and you're good to go!

Event calls are calculated from bank $CA. So you want to do $F1 - $CA = $27. Your B2 command here would be B2 00 50 27.
