Thanks for the clarification., Dennis.
The document I was looking at explicitly stated that the 2nd PF2 write HAD
to be on cycle 45 - not before or after. This works fine with the single
line, playfield only kernel.. It was quite easy to get it working actually,
the sizing was another matter.

Here is the timing currently:
LDA PFRData0,X ;[27]+4 = 31
STA PF0 ;[31]+3 = *34* 27>z<48
NOP ;[34]+2 = 36
LDA PFRData1,X ;[36]+4 = 40
STA PF1 ;[40]+3 = *43* 38>z<54
NOP ;[43]+2 = 45
LDA PFRData2,X ;[45]+4= 49
STA PF2 ;[49]+3 = *52* 48>z<65
And it still isn't working...
I am only drawing the playfield every other line.. is it possible that is my
problem? If I have to write the playfield every scanline, this is going to
be very tight...
