I don't know why this is so hard to find information about.
I have a Japanese PSP and want to swap how the circle and cross buttons work so that they aren't the opposite to all my games.
I had 1.5FW until today when I installed m33 2.52-4. I downgraded back to 1.5 thinking that the FW file I used would be non-Japanese and thus make the buttons the way I like.
Well, I was wrong, unless the 1.5 FW that came with the recovery files I downloaded was Japanese.
Is this a hardware thing? Is there some way around this?
