When you got ur Game in ur HDD do you need the original CD or sumthin'Hello, i only got my jtag a few days ago, and i had NO idea either, but Its pretty simple tbh.
Turn your Jtag on.
Install MW2 on HDD.
Replace the real default_mp.xex with a patched one.
Place the TU6 file in the cache folder.
Then get your patch_mp.ff and paste it in the MW2 folder.
Then run default_mp.xex which is in the same folder.
