Before I reinvent the wheel, can anybody comment on the feasibility of
producing a non-repeated playfield by writing PF0, PF1 and PF2 chasing the
scanning beam before data required for the repeated section?  Of course,
there would be two lots of writes required per scan line, but I'm interested
to know if its been done.  What I'm asking, I guess, is when it comes to
drawing the right half of the PF, does the hardware re-read the PF
registers, or is it buffered internally somehow?
Cheers
A
