Well I got it so I didn't make it myself... anyway it won't open as virtual dvd drive after mounting it with alcohol120.. So i believe the file is corrupted.. thx anyway!
This wouldn't happen to be Ninja Gaiden, would it?
Either way, you have to do the normal steps to putting it on your HDD, plus one extra. Download MagicISO; you'd be able to get a copy from Google.
Using MagicISO, covert the MDF to ISO. You don't need the MDS, as it functions like a CUE, not necessary in most cases.
With the ISO, use an Xbox ISO extrator; I prefer XXXISO. XXXISO has never failed me, while most of the others have. XXXISO can be downloaded in the tools section of the site.
From there, just transfer over the entire file to your Xbox. If you want to burn it to DVD, just use MagicISO and go straight to disc.
well I guess you know where your problem is then don't ya....
