yeah you do and there isnt any new chickhen yet, although there is a way to run custom code in the later firmwares by using a game that was show on the psp go i dont know how that would translate to a psp 1000 or 2000 but I am sure it is possible, also i think that Dark~AleX may release a custom firmware for the PSP Go and with that release a new method of downgrading from newer firmwares, I thin that he wil be waiting for sony to sort out the new electronic gaming system before he releases a hacked version of it.
