wifi multiplayer connection problems

[shik1]

here's the set up:

us 1.50 psp (tricked to ver 2.0 with wab)with us ridge umd

uk 2.00 psp with ridge umd

we can see each others games when searching and hosting games on multiplayer..but it loses connection when the race is about to start.

same with virtua tennis.

and burnout legends game sharing sends the game to the other psp fine but sticks on the loading track screen??

whats wrong?

do the psp's need to be on the same firmware?
the 1.5 is tricked to 2.0 so it should work...?
