So I picked up an AES today... Haven't owned once since I bought a Gold system in 1995 just to play Samurai Showdown 2.
Was playing KOF '96 on it, and it froze up once in my second match and after I reset, it froze again in the first match.
What freezes is the sprites. The music keeps going. Oh, wow how much better is that Neo CD much, huh?
Anyway, it's night here in Japan and I'll test it further tomorrow; but what's the community opinion? Just clean the connectors on the cart? Is it a board issue? A signal aliens are invading?
