in the custom firmware one, you'd have to patch the mw2 file, and then copy the stuff from there, and load it into your updated ps3 with a usb (in a nut shell)
am i correct?
Almost.
The part where you mentioned the USB is incorrect, you would actually need to connect both PS3s using an ethernet cable then data transfer between them using the option under System Settings :y:
