I've seen roms pass checks and still have faults similar to that, according to mame b08, b09, b10 and b11 are graphics roms with b08 being sprites. try replacing it.
Not to be rude but why would we buy from you with a markup when some people have been in a waitlist for months?
Buying directly from him would be cheaper and fairer would it not?
I know this is late but remaking a kickplate is your best bet, mine was dinted beyond repair.
I cut and folded some mirror finish stainless steel, then I fit, drilled and pop riveted it.
I noticed you powdercoated some of the electroplated parts, it's probably too late now but electroplating isn't expensive and keeps things original.
These are some parts I got done recently.
