You will still need a CFW PSP if you want to convert your own battery (soft-mod).
Hardmod not recommended.
Go to qj and search for an "newbie installer". That's what you need for the stick.
Be sure to use XP, not vista.
Well I did what you said, which by the way, thanks for your help, and it came up with a thing 'too many results' but it showed some, and the first result was 'Homebrew Installer Maker'. I'm just wondering if that's what I'm looking for.
