That whole serial number thing with the Neo Geo AES units seems kind of suspect to me. The point is that ALL Neo Geo AES systems have horrible video quality. Some might be a bit better than others, sure, but they are all bad... especially for such a high dollar system! Even RGB out looked muddy and washed out. That's why I had an RGB bypass done. Now my RGB looks great when converted into component video. No clue how composite looks.
