the game could not be started(80020321) psp
 

hi!! i make update for my psp 2004 version 5.50 gen-c (full) and when try to play games i have error the game could not be started(80020321) can you help me ?

did you tried this

This error is appearing because there is a setting in the hidden configuration menu that is set to require a UMD game disc to be in the PSP when it attempts to load.

Turn off the PSP, then hold the R button down while turning on the system. You will be in the Recovery mode/Configuration menu. Choose configuration, then go to the 5th option, and press X once. This will switch it to "NO UMD". Then press X on "Back", then "Exit". Once you restart you should be able to load the ISOs, CSOs etc. without getting the 80020321 error.

i don't have experience with psp
but i have repaired this problem before in ma psp 5.03GEN-A
its too hard but you will do it if you have some patient
finally in this SITE you will find all what you need to hack your PSP
Good Luck

I am having same problems as of now after updating PSP 2000 with gen d3
old games disappeared and remainning games were corrupted

hey people iv got the solution : This is what you do : when you are on the main menu (xmb) press select and this menu will open change teh things on the menu to this :
CPU CLOCK XMB - 333/166
CPU CLOCK GAME - 333/166
USB DEVICE - MEMORY STICK
UMD ISO MODE - SONY NP9660
ISO VIDEO MOUNT - NONE

USE DIRECTION PAD TO CHANGE THE OPTIONS LEFT/RIGHT

CPU CLOCK XMB - Default
CPU CLOCK GAME - Default
USB DEVICE - MEMORY STICK
UMD ISO MODE - SONY NP9660 / M33 Driver
ISO VIDEO MOUNT - NONE

U may get error on others game if u do not use the following rules.
and try install ******* firmware promethus-4. it can run require f/w 6.35
