He wants to rip games then use the cpxmenux app to put more than one game on a disk, but when you put more than one game on a disk (or deconstruct an ISO for that matter) the files are no longer in the best order (access time for finding a file turns to crap) but if you run them through the Xbox SDK it places the files in the best order (access time is quick, things load quicker and play smother).
So what he and I for that matter want to know is how to use the Xbox SDK to create an ISO?
Under stand now?
