I requested account to add pinouts on neo-geo wiki (PRO-C0) but without success. If someone is in touch with people which can know why ?
And up for my problem. I wish avoid to change Pro-B0 or Pro-C0 for nothing
I had one dead pixel output on the ZMC2, now it's ok on this point.
for the issue, FIX of the game test don't have the blue color inside.
there is no border color on the crosshatch, just the white part grid.
All tests passed with SMKDAN, controller, RTC, memory card detection, ram test loop...
I don't know precisely how are generated colors bars, but I think it's either the 4 low Palette bits of the C0 (could result in 16 colors steps) either a combination with the B0 and its upper bits palette.
Is someone can confirm if the LSPC-A0 is out of concern ?
with the original Eprom, just after the RTC garbled green screen, It's stuck in a solid plain green.
all pins of 273 seems active but I'll cross the set.
