ok, make this bootleg work.

p2 controls don't work if the 'cocktail' dipswitch is set, but since I see nothing to flip the screen I suspect that mode simply isn't supported in this bootleg.

@ -7,17 +7,22 @@ single PCB with 2x Z80
similar looking to the '1942p' and 'spyhuntpr' PCBs
P2 inputs don't work
P2 inputs don't work in 'cocktail' mode (maybe it's just unsupported on this PCB?)
DIPS etc. are near the 2nd CPU, should it be reading them?
visible area is 16 lines less than the original, otherwise you get bad sprites
but I think this is probably correct.
some sprites are a bit glitchy when entering playfield (see title screen)
probably an original bug?
