alright i relize there are tons of posts about this but i have a specal situaton... i recently bought a used, modifdied, x-box (or so i think). yet as far as i know... is nothing. how do i know if a modchip is installed, if its "flashed" or if i have extra memory... ect. for the basic use of backing up games onto my x-box (cuz im lazy, and it'd b cool). i need a quick rundown on how to check if i have a mod-xbox, what else i need, and how to make a my no CD machine. oh and im new at this so keep it simple.
