/* The dark screen issue is present on the real pcb, although much less noticable than in mame.
The bootleggers have patched out the code which modifies the brightness/fade component of the palette word.
This is somewhat strange as unlike some bootlegs, this board DOES have the brightness circuitry (2x 7407's, 12x resistor dac) populated!
The below patch fixes the issue: (for pcb fix burn a 27c040 of w6.u222 with 0x8f7=0x6b)
