RIDGE RACERS-WI-FI
The first step is to have two PSPs and two copies of the game, you're going nowhere without them. (But look at the how-to section for XlinkKAI - a system that allows you to play Wi-Fi games over the net)
Then one needs to be put in 'Playor' mode and the other in 'Playee' mode. (these are terms I made up, i'm a lawyer, so they mean something to me)
