I have been seeing lately that there seem to be multiple versions of some neo games. Is there a thread or site dedicated to listing the different revisions, what's different in each, and what board set or chips have each revision?
using the search function is an art form, but you can get good results pretty quick. If you're too impatient to practice, use google and add "site:neo-geo.com/forums" at the end of your search words [only works for the public parts of the forum, of course].
