I had a silly issue with the iOS version and this game, so might as well throw the solution out for future generations:

If you get the message "save data save failed because the specified file was not found" after downloading a save file for the game - this might happen if you transferred a save file with something like iFunbox, for example - you'll need to fix permissions.

Install a terminal emulator from Cydia, then execute these commands:

su (it will ask for your password, the default password is Alpine)
cd /var/mobile/Documents (go to the Documents folder)
chown -Rv mobile PSP (changes the owner of the PSP folder and all the things in it to mobile)
chmod 755 -Rv PSP (sets permissions for the PSP folder and all the things in it to 755)
