Could be that the 05 is a manufacturing run prefix, with 524 being the unit number in that run. Seen similar things in Navi screen serials. Surely they didn't make 1/2mil+ CDZ?
it could be yes, but don't forget during 4 month, end of 95 and begining of 96 SNK sold more than the production and the Motherbord of the CDZ are the same
neo geo AES controllers just a quick question, are the large control sticks from the original AES system compatible with a CDZ?
