My guess would be the blank stickers on the EPROMs. They look suspiciously clean and unworn and usually at a bare minimum the stickers will have some kind of text indicating which EPROM they are. I don't think I've seen EPROMs on a Capcom board that don't at least say Capcom on the sticker. The Macross does have a bunch of SMT chips on the MASK board, I'm wondering if maybe the EPROMs were some sort of version upgrade someone DIYed? I suppose I could look and see if there are multiple versions but that's more work than I want to put in.Why are we thinking Macross Plus is a conversion? I sold mine off awhile back but this one seems look exactly like mine. Blisters and caps on mother in same locations. Daughter has same chip layout and same silk screen location and date. I think that one is also legit.
If both boards came from the same source chances are they are booties since both sticker sets are so clean.
Mine looks exactly like Cory's.
