So I have PSP Slim Version 3.73

[orion233]

I just bought a PSP slim and want to emulate it because my PSP Phat broke. I know how to emulate perfectly fine with a normal PSP but when it comes to a PSP Slim Im confused on all the guides. What exactly do I have to do to my battery? And do i have to downgrade first? Or can I upgrade from 3.73 to Dark Alex's 4.01 M33 Firmware without doing anything to the battery?

I had some trouble with my brother's, the instructions weren't very good.

Hopefully, you can get a hold of a custom firmware fat PSP...cause you need to make a pandora battery.(with fat battery NOT slim...fat batteries fit into slim.)

unlike for fats though, you need to get the depratar clemeto or whatever it's called that emediately sets you off with 3.90. Follow the instructions for that...it's much easier than the fat one cause you don't need to format.

When you finish, you can use the battery/stick combo on fat psp's too.
