umm look in the xbox 360 exploits and hacks section 4 tut

i don't think modding your gamesave works for zombies but if you extract your profile and put it into a hex editor

search for set gpad_buttonsConf and you'll see set gpad_buttonsConf"buttons default"

change "buttons default" to "screenshot-----" (- = a space) so it's 5 spaces

then save it and use a hash block calculator then put back onto your HDD and choose solo nazi zombies then the map you want

i wish ps3 had haxssssssssssssssshjghbjs
