game won't save

[critical]

alright, i am using a psp 1.5 but i upgraded it to 3.80M33-4

i have put the version 4.0.2 inside the /psp/game and everything played well , even if i put into /psp/game150 , still the same it plays well

the only thing is, the game is not saving , no matter which game i played, anyone can help?

thanks
