The game Endless Duel is really fun! I downloaded it a while ago and I just hope that you can download it from my site. Up to two people can play and it's a lot better then the other GW game for play station. My opinion, but the only character you can be from Gundam Wing is Heero on the Play Station version, Gundam Battle Assult...
CLICK HERE to download it. The Zsnes is there, too, but you need winzip to "unzip" it. You can download Winzip at HERE.
