Yoshihiro of WAB has released a method for swapping the Circle and X buttons on the PSP.* If you weren't already aware, Playstation in Japan uses Circle as the classic "enter" button, as opposed to X in the West.
What it does: It swaps O and X buttons for the JAP PSP 1.5 (only JAP&1.5!) So your JAP psp become like US.(only for buttons)
How?: Just follow instructions on your screen and don't forget to plug you AC adapter.
How to reverse?: Easy you just have to go to system setting ==> Restore default Setting.
