well you could have googled a bit more or looked around the site

but first u need all the files from disk or iso

if u have an iso u can use xbox image browser to extra to a folder named mwf2 or what

ever u like and extract

if u have the disk u need to create the folder to put al game files in "mwf2"

and use xex-menu to rip the files from disk to usb stick or usb hdd

once in xex menu with your mwf2 disk in tray navigate to your folder
on usb mfw2 hit y button , copy disk ..should start and show a progress bar

when finished take usb out of 360 put in pc and copy hacked files to that
folder on usb , it will ask over write yes

then put usb back in 360 and lauch xexmenu and browse to your mwf2 folder
and select the file defualt_mp.xex press a it will lauch game

idk your codes some auto activate some need activated

a lot of them are activated by selecting lefty buton layout and pressing

on dpad up right down or up rt down or both , its shoudl restart the timer


good luck
