So i bought a pandora battery and a magic memory stick off of pandorasales.com. I Successfully put CFW 4.01 m33-2 on my psp 1000. I have gpsp on there. and I had some iso's working. But some of mine wont even show up under the memory stick when I put them on there? Do i need to upgrade my CFW or something? one game that dosen't work for exemple is littlebigplanet. Thank you! any help is greatly appreciated.
