Give me/or try to search the numbers on the capcom stickers on the roms, I normally find a link to KLOV or somewhere when someone else has a board to i.d and normally you see a reply with the correct answer.
So go for the numbers on the rom labels instead of searching the board no's.
Hope that helps.
(P.S let me know what they are, always interests me)
P.P.S I did pass on the KLAX marquee etc... to Unit504 hopefully between you your getting it sorted.
