So my Fallout New Vegas works perfectly fine on my normal Xbox and has hardly any scratches. Although, I want to play it on my JTAG (modded Xbox 360) so I can do some mods on the game and have more fun with it. When I start up the game the beginning loading screen that show the companies load up very slowly with no sound. Then when I get to the screen with the guy holding the magnum, the text doesn't load up that says "Fallout: New Vegas" and "press start". So I can't continue on and when I go to the Xbox 360 dashboard it freezes the JTAG. I can play other games perfectly fine in the JTAG and like I had said in the beginning my disc has hardly any scratches and works on my normal Xbox 360.

I would really appreciate some help. Thanks.

I wonder why a game doesn't load on a hacked console - If you're going to hack the console research how it works beforehand

You will get no help with modified consoles here.
