Hello there.
I think this forum is mainly for USA players . Anyway. I am from Sweden.
Just the other week I tried out my network adapter
Interesting to see what happend. I hope it is ok to post links.
The main problem is that the games you want to play are no longer online, and there are no alternative servers for them (may be with xlink kai).
You will be able to find a list of all the games still playable (and their DNS to set in your PS2 network configuration file) here : forum/viewtopic.php?f=10&t=1880
