I don't understand the patch thing.. I seriously tried to have an ally at mirage tower at Ragnarok Online DS , No one was there..

people had wifi issues with PS0?

After playing it couple of times i thought the online mode kinda sucked so you aint missing out on much.

I played the Japanese version and that worked online fine without any need to patch.

My guess is no one will be playing this game now so it would be really hard to get a random match.

I don't usually see many people on these games where you have to get to a certain point in single player to start playing wifi. The best way to do it is to find someone on a board like this and schedule a session. I'd be down but I just haven't gotten that far yet.
