Gaming Little Help?

[Lucashen]

Not really sure if this should be posted here but and i know i already made another thread, but seeing things get more attention here...
I've bought a 1001 psp on 5.50 gen d3 and got some issues with it too.
some games work and some games don't, for example patapon 1 and prinny cirbth do not show any image for gameplay, littlebigplanet gets stuck on the second loading screen after a gray screen that needs some short of confirmation.
while patapon 2 works perfectly, along with some other games.
i had a test on a 3000 psp with the same iso file and it worked correctly.
can anyone help me?
edit:
quick update, no patapon 2 is not working, same problem.
EDIT:
Quick images about the problems i'm facing.

Prinnie's menu will show up.

But then it stops at this screen and freezes the psp.

Upgrade the FW to 6.60 then to PRO C 6.60 CFW for better game compatibility. That CFW is you have is ancient.

The question that i forgot to mention is that i was already on 6.60 pro c cfw before downgrading. The store Downgraded it with pandora and mms to see if it wasn't a bad jailbreak and it still didn't work.
