Hi Guys...
The only place i think the peeps will be able to answer me regarding this question is here , I have the Go!explore ordered from ebay and am waiting for it to arrive, but its just the GPS receiver and does not come with the umd , so i managed to download a copy of the umd and its a .iso file.
My psp is on the latest legit firmware , and i just wanted to find out if its possible to use the downloaded iso
