Save Data Corrupt After Installing CF Update

[kidunkown]

I need help, my psp (not psx) save game data says that it is corrupt and that it can not load. After upgrading custom firmware from 3.71 -m33-4 to custom firmware 5.0 -m33 any suggestion?

Also I tried downgrading back to 3.71 and my save data seems to work fine. So is it because of the upgrade that made my data mess up? Is it possible to upgrade without corrupting my data?

The game is also running as a .CSO file in my ISO folder. With the m33 driver. (I also tried the other drives and still no luck) and also tried scan for errrors, saving it to my computer and putting it back in and still the same.

Thanks For Your Help In Advance.

depending on what game you are playing...some older games cant play/load on higher fw than 3.71.

is there a way to use popsloader to play the game in 3.71?
