Basically, it would ask you which CFW to install and you would choose, say, ReiNAND. It would patch signatures, install BBM or FBI, and download the needed files based on the current system version, along with some other things like an FTP client, a file manager, and that kind of stuff. Then, ask the user to copy there SD Card over to there computer, and once they have, format emuNAND, and tell the user to put there stuff back on the SD Card. Then just install Menuhax, and restart the system. That's just the basic concept, so I'm sure I'm forgetting a lot of things here. Also, is it possible to format emuNAND without erasing everything on the SD Card?
