Thinking someone here that understands the emulation maybe able to help.
I have been working on a Exotica, the manual states that dip 5 of the first
switch bank is unused and default is off (http://www.solvalou.com/subpage/arcade_dips/C/crusnexo), but if I turn it off the game reports U18 and
U19 as bad, turning it on all is green and pass. Ideas on how an unused switch could cause this. This is game version 1.6, I plan on reading the proms this weekend to see if the checksums are correct.
Also thinking of updated the 2 needed to get to 2.4, anyone know where to buy 27c160's in the USA at a good price?
