Could I do an exploit through FTP? Or do I need one of the games?

if u dont have the memory card or a way to connect your xbox controller to the pc etc etc.... just use "XBoxHDM" and the UXE auto-installer exploit that works with the XBoxHDM package. (only about 20MB ish between the two files)

NOTE: u will need to open up your xbox case and connect the xbox's hard drive to the pc's IDE cable etc etc... but it works flawless

so basically im saying... u dont need ANY games or anything to get this to work besides the programs i said above... basically that XBoxHDM is run from a bootable cd that u load on your pc.
