I haven't found anyone else having this problem.
I'm running CFW 3.80M33, on an original Phat PSP. I downloaded the Patapon demo off the Playstation Store, but when I try to run it, it says:
"Game Cannot be started(80010013)"
I looked up that error code here, and it equated to "Media/Device cannot be found", which doesn't make any sense to me.
I currently have the MGS and Worms demo downloaded off the same store, that work fine.
Anyone else had/having the same/similar problem? Anyone with any advice on how to solve this?
I'd really like to try this game.
