If it is a UMD:
Hit SELECT to access the VSH menu.
Set UMD Mode to NORMAL
Try to start the game again
If it is an ISO/CSO:
Press SELECT to access the VSH Menu.
Change UMD Mode to m33 driver
If that does not work:
It may need to be patched. Go to http://www.youtube.com/user/ubeenstryked and look for the video about PATCHING ISO FILES.
Once it is patched, you should be able to play it.
What you need to do is disable the umd from within the custom firmware menu. Completely turn off the PSP (hold the power button up until it turns off). Then while holding the right shoulder button, turn the PSP on. The recovery menu will load. Select configuration and then disable the "no umd" option. Exit from the recovery menu and insert a umd disc into the PSP. Make sure auto start is also disabled in the PSP menu settings. You should now be able to run your game.
hold the right shoulder button and turn the system on. it will go into the recovery menu. select configuration and goto umd mode. it will say normal UMD required. press X and it will change to M33 driver. now select back and then exit. system will restart. ENJOY!!!!
Had the same problem also but just solved it..
Just go to Recovery then Advanced>Advanced Cofiguration>Execute BOOT.BIN in UMD/ISO --> Set this to Disabled..
