Notes
PCB is working, but car sprites are missing interleaved lines, probably due to 2 missing EPROMs
update 20071001: from HAZE:
yes, that's exactly what's in those roms, the alternate lines of the car sprites.. basically the car sprites are like this
rom 19 .. line 0
rom 19 .. line 1
rom 21 .. line 2
rom 21 ..
rom 18
rom 18
rom 20
rom 20 .. line 7
rom 19 .. line 8
rom 19 ..
rom 21
rom 21
rom 18
rom 18
rom 20
rom 20 .. line 15
etc.
so without 2 of the roms (20/21) you're missing half the lines of the sprites.
