ok, i downloaded a couple of games of psp. but i dont know where to start. i haven't modify my psp yet. as i look into my psp's system information. my system software version is 2.81, i this where i should look into the versions that you were talking about? if i am correct, so my psp's version is 2.81, i was looking for a downgrader of 2.81 but i haven't seen any downgrader. should i upgrade it first to 3.+ then downgrade it? or should i downgrade it straight? please help. thanks.
