I managed to start it ! THIS IS HOW: ( for JTAG/RGH ) 1. Google and download the program, called Wxpirs version 1.1. ( or another program of this kind ) It is a program for opening Title updates and DLC packages 2. Then open the Compatibility Pack file with the program and extract everything ( File / Extract All ) and put it in your game folder. 3. But still keep the downloaded Compatibility Pack in its original place , in the content/00000..... folder ( don't delete it ) 4. You need Title Update 1 5. If you still have any problem, try to unlock the CP first, with xm360 ( or similar program ) I am sure , that will be easier ways , like the Nuketown xex edit for BO 2, but for now this works !
as stoyaninho says this works i didnt touch dashlaunch what great gang we have on xpg the support is second to none so follow his instuctions and your golden
