Pandora's Battery help

[fuelthescene]

Hey all.

I have created a Pandora's Battery in the past for my PSP fat. It has 3.52 m33 on it and then the upgrade to m33-4. I have used it to put custom firmware on my brother's fat PSP and it worked flawlessly.

Now I need to put custom firmware on a friend's
Slim PSP. Can I just put the 3.71 m33 install on the magic memory stick and delete the 3.52 m33, or do I need to completely remake the card?

Any help would be greatly appreciated.
