2 psp's Both with a UMD disc of gran turismo One is my cutom hacked psp 2000 (with custom shell-firmware is 5.50 GEN D-2) The other is a gran turismo special edition 3000 running 6.20 OFW I set the channel from auto matic to channel one after the first attempt... Ok it's simple, the game lags on the hacked psp when vsing the OFW psp A car going 200km's on the hacked is being beat by a car going 100km's on the OFW-and it's obvious that there is lag judging by the way the car is seen moving on the ofw-that and it feels slower than singly player mode just a tad than normal (comparing the CFW"S play speed to multiplayer) So why are they lagging? Also..when selecting cars, it may reset the choise of the user joining a group (regard less of the 2000 or 3000) On a side note...game sharing on other games seems perfect-just gran turismo that's playing up.
