maybe an old one like 0.9.8 or r1888.
but don't expect support if you have a problem with one of those.
Do you think maybe a different version of the iso would serve to help as well? Maybe PAL iso?
you have the game twice ? maybe this one won't freeze on your PS2, then.
Twice? Well I only have one copy, but I wrote the iso to the disc and it still froze.... I mean, do you think downloading a different version (PAL or something) of the iso will run faster in battle? It only runs at 35-45fps during battle...
downloading an iso is piracy. You're allowed to use your own disc (and then turn it into an iso if you want) and nothing else.
your pc is underpowered plain and simple
