Ok, I've got two PSP's here. An old fat one, which doesn't work properly - the buttons are all fucked, but the battery is still fine. A a new slim PSP. The old fat one is already hacked, running custom firmware. The new slim one is running official firmware 6.20. What I basically want, is my slim one hacked, and running custom firmware. I realise that to do this, I'm probably going to have to make a pandora battery. I think I have everything I need to do this - an old fat battery, a memory card, and a USB cable. Can anyone link me up with the relevant guides to accomplish my tasks, or point me in the direction of a useful site? Thanks!!
