Better Pandoras battery/Desperado centrino or somthing

ok i have a few MORE questions about this stuff.

1 CAn you make a pandoras on a PSPslim and use it on a regualar psp (slim FW: 3.60, FAt FW 3.71)

2 Do you need to update to 3.XX M33 for making a pandoras battery on the slim?

I need answers ASAP. Thx for the help.

cqan i pit 3.60 M33 on a 3.60 by just using a 3.71 fat and a 3.60 slim?

You'll also need to use the fat psp battery if im not mistaken.
