Hi!
So basically I've been watching a stream on Outbreak recently, the person shared the link how to set up everything and yeah it worked, had issues with BIOS but got it figured out, I'm pretty happy I always wanted to play Outbreak multiplayer back then when it came out but PS2 + internet wasn't really a thing in Europe at that time, so yay!
Gonna have to play the episodes again to unlock harder difficulty I guess and remember how to play!
