DIRECTIONS
install xex menu to your jtag by either putting it in a folder called "CODE9999">"00080000" THEN THE FILE U DOWNLOADED (im pretty sure if u downloaded xex menu it comes like that, hook up ur tansfer cable to your hdd and out code999 in partition 3 > content > 00000000000000

now that u have all that done now u need to put in MW2 and load it up, go to xex menu and click y or x( depending on your xex version) and it should come up with copy,paste ect now go down to the bottom and click "create"witch will create, create the folder in CONTENT and call the folder "games" and them click "copyDVD" wait for your disc to pop out, once it pops out pop it back in then click confirm, MAKE SURE U COPY IT INTO CONTENT and wait untill it copys all the files into that folder

now its simple from here, you should have all the files from your disc into the folder called "Games" now get those files u downloaded b4 and cop and paste them into the game, once thats done so click on the "DEFAULT_MP.XEX" THAT WILL LOAD UP THE GAME so ur at the xbox live, and split screen page, click on split screen
