Hello I just recently hacked my psp 2001 by making my battery into a pandora by scratching the spot at number 19 coupled with a magic memory stick to downgrade my 6.37 ofw to 6.20 official firmware. I then reverted my pandora battery back to regular by filling the scratch with a pencil. Now I'm using hen 6.20 Tn-D and using prometheus iso loader to play isos/csos. I'm playing God of War CO and I noticed many times during each level I play I suffer 5ish second "fps attacks" if you'll call it that where the frames per second drop significantly for that 5ish seconds and then it reverts to normal. Also out of game cut scenes can stutter alot sometimes like as if its having trouble playing them. Do you guys know what the problem is? I'm thinking my my battery is the problem but maybe not. Any help would be appreciated as the fps attacks are very annoying along with the cut scenes.
