Hi there. I ended up finding out about the games, and decided it would be fun to try it out with my brother. He isn't registered yet, but he will be soon... This gave me a nice excuse to mess with our three PS2s, too.
We have two fat PS2s with hdds set up and softmodded (his is hdd softmodded, mine is card). I've tested both systems, and OPL is fully functional on each (one of the hdds is unofficial, a whopping 20 GB of space; yes, that is only one zero). I still need to get outbreak 2, but I think we will most likely keep it to file 1 until we're comfortable with the game, and are sure we like it(why get both, if you don't need both).
Anyways, I probably won't play online with anyone else besides my brother until I gain some competency; if you don't see me join a random room, don't feel too bad.
Also, thanks for making this server. I really enjoy seeing projects like these.
