I was in the photo store and saw them selling two LR44 batteries. I bought them for 50 bucks and tried using them on my old game and watch. First try was Mickey and donald, screen is blurry but still working. Second was Chef, screen still works. yey Third is the Popeye in Panoramic Screen (complete in box). works great! Ahh those where the days when PSP was just a dream. Do you still have your game and watches?
