Ok, I am considering purchasing an xbox, but I have a few questions concerning which route I should go, and even relating to mod chips. Firstly, I have two choices, I could go pick up a new xbox at walmart for 150$, or go for a used one at EBgames for 119, and a warranty for like 22$ that supposedly covers anything. I would like to be able to use a solderless mod chip if possible, what would be a good recommendation on them? Farthermore, I am trying to figure out what exactly would be involved in making a back up of a game? Is it just pop in computer, make an image, or something else I read said you have to copy it in the xbox, then upload it to your computer then burn it?
