So I'm planning on getting a PSP Slim soon and want to be able to run backups on it.

So to be able to do so, I would need to run a custom firmware, like the 3.7 M33.

To upgrade a store-bought PSP to the custom firmware, I need to use a modded battery and Magic Memory Stick to made Pandora Battery.

The modded battery can be the Datel Tool one, or make one myself by removing pin #5 on the chip insdie of it.

This is where I'm mostly confused at.

The memory stick can also be made via a "Universal Unbricker V3." The program will have all the files needed to convert the regular memory stick to a MMS. There is no need for the registry files or kd files.

With both, I can start the installation of the custom firmware. And with the firmware, I can play backups in ISO with an ISO loader program.

Is that all correct?

Also, do I need to keep the same memory card in to use and run backups, or can I use one card for the installation and another to place my backups on?

I see. And the registry and kd files MUST be from a PSP with 1.5 firmware?

Sorry for asking so many questions, but the totalnewbie installer will pretty much create the necessary files to get a working memory stick?
