Here's how to set things up and use the Wi-Fi game connection feature:
* Switch on wifi, All PSPs choose p2p in Wifi Game menu. You should also change your controller as well. P2P mode could work and all psps have display.
* Every PSP choose the same game. If you are using p2p mode, please use sync game menu once or several times on the 2nd PSP. You can press left/right to select sync game menu on reset game menu.
