Ok im thinking about getting an xbox and when i get one i want to chip it asap. i allready have a ps2 that i chipped myself and basically heres what i want to know about the xbox.........

whats the best chip for the xbox and any hints as to where i can buy one-
i only have dvd+r, the xbox can read those right? (i know the ps2 has to be a certain version)
what programs do you use to make the backups, can i use RNM the same way i make ps2 backups?

much appreciated and feel free to add anything else i might want to know about chipping the xbox

thanks
