I have heard that some PSP games from different regions won't work together in multiplayer. If people could confirm combinations that work it would help in deciding when to go for a cheaper version available from the USA and when it's better to stick with an European version.
Example: I have played multiplayer of Game X between a Japanese and European version.
Or is such information already available somewhere?
