Just install the "PSP Adhoc IM Ver. 3" folder into
the "ms0:/PSP/GAME/" folder and it's all ready to go.
everything should be self-explanatory.
if you can't get it to work then you probably don't
have a customized PSP, if so look elsewhere on the web.
If you're looking for a Wifi app then you looked in the wrong
place. This is an ADHOC application.
