maybe you should ask us about 3.10OE first..

1) update to 3.40OE
2) go to recovery mode (press R when turning PSP on from coldboot (Hold power button up for 10 seconds to turn off completely) go to configuration and change 3.40 kernel to 1.50 kernel in the game folder thingy.

Good luck

Even if they say they need 1.50, 99% of the time they will work on an OE firmware, like Wally so rightly said

I think this bro has official firmware.

If not, move all your brews to GAME150 from GAME.

if you do have OE then yes, move all you games from game to game150. you have to have both folders even if the "game" one is empty.

if you are unsure of your firmware then on your xmb go to system settings then system information. you system software is your firmware.
