Try this file out. It is the one I use for testing PSP battery runtime so I know it works.
As for games on the memory card you want to load custom firmware. You should get a pandora battery for this. See my thread in this forum
You will need "PSP Grader" or "Despertar del Cementerio" to set the memory stick up to work with pandora battery. 100's of guides on the net for it.
