A new, easy to use app to show the state of the IdStorage in your PSP, and make corrections to common problems caused by the old downgraders (TA-082/86 only). Will dump keys as well.
EDIT: 2007/09/03 v1.2 released. Major rewrite, easier than ever to use, no external keys needed, can create keys if needed (for hard-downed PSPs), and the colors are inverted to make it easier on the eyes.
