so I was looking at this this tutorial; http://www.xbox-scene.com/articles/swap-dvd.php and I notice that by modifying the xbox this way it can only read back up copies. there isn't much elaboration there, it mentions putting cd-r's into the xbox. but surely a cd-r wouldn't be big enough to hold all the data for an xbox game? you can only burn xbox backups onto dvd-r discs right? also, is that all there is to it? or are there any other modifications someone would need to make to the console so that it can play a backup of a game? presumably just follow a tutorial online for extracting a file of the game (iso?) and burn this onto a blank disc.
