I just tried this, and all I had to do was write 1 instead of 0 to CTRLPF. I even tried some different bitmaps to make sure the transition was right -- it's on EXACTLY the right cycle with the code unmodified. Of course this is like the first 6502
STA PF0b can be rewritten as early as cycle 23. In my mod it's at 31. STA PF1b can be rewritten as early as cycle 29. In my mod it's at 38.
