Oh!
Well as I said in my first reply...
What is XLink Kai by the way?
Hmm... I've not looked into WiFi for the PSP at all.
I'll have to see how the XLink works... sounds very intersesting.
Does this work for normal UMD's? If it does, no modifications have to be made to the homebrew application that support AdHoc.
Unfortunatly I cannot answer this question in depth as it's out of my knowledge.
If you post this on PSP-Programming or PS2Dev Forums, you'll get replies by people who really know their stuff!
Sorry couldn't answer you questin in depth.
