But Big Bruno, isn't it true that there have been several revisions to the Neo Geo cart motherboard over the life of the system? Some have a daughterboard, some don't, some have better video output, etc. My serial number is 013XXX, pretty old . . . but I need to check my other two systems to see what they are.
And the Japanese cart systems are very light, compared to U.S. . . . due to shielding, I think.
I really wonder if these "high serial number" systems are that much better than the low ones . . . maybe Jeff Kurtz could answer this point. He modded my Neo cart 013XXX and the picture quality and sound quality are excellent . . . how much better could they be with a newer motherboard revision? Jeff?
