I've heard that the X and square buttons are backwards on the Japanese PSP. With firmware 2.0 upgrade (which is Japanese right now), does this make your US PSP's buttons backwards? Or is the backward button thing related to the game your running? (For example, playing a japanese version of XYZ game reverses the buttons, but playing the american version makes the buttons "normal").
I recall that when I played the Japanese version of FFX on my modded PS2 that the buttons were backwards, but when I played the american version the buttons were what I expected.
Anyways, thanks for the info and clarification.
