Download the Kalliera client SDK v0.9
I would prefer you download ePSXe 1.5.2 and cyberpad 1.3 instead of ePSXe 1.6.0 and cyberpad 1.4.
Personally for me it's because I use a different configuration for online play and offline play. So I use ePSXe 1.5.2 for online play and 1.6.0 for offline play.
Btw: at the moment I have these 2 player games: Tekken 3, X-Men Mutant Academy 2, Jedi Power Battles, Bushido Blade 1 & 2, Bloody Roar
, FIFA '05... Hmz I think thats about it. Maybe 1 or 2 more.
So email me when you are set.
