For a lot of online games you don't even need the 'Setup Disc', that's just for stupid Sony ones.

And the comment above regarding the router needing to be for PS2 only isn't true....

Just type in 'PS2 online setup' in google and you'll find all the info you need.

And for a list of online games, take your pick:

Get yourself a copy of Conflict: Global Storm, takes 5 mins to get online and you can play the whole missions with 3 other players (and talk if you have headset, SOCOM headset does work) with all weapons and levels, including extreme, very friendly players and active, at least 20 missions every night, (GMT: after midnight) plus you can play and make your own levels.

I've tried SOCOM, GR, COD etc and this beats them hands down....try it, you will not be dissapointed, in fact that's where I'm going now.
