He used an exploit in thug2 supposedly. He has not released how, (except to 'select developers') but there is speculation on how he did this. Thug2 has something to import face mapping... which allows you to browse the psp's card. I dont have this game so i cannot test anything with it.
They also have made claims of having an sd k.
