your so stupid why the hell do u buy a jtag and dont even know how to load the default me xex and click on system link

i know how to do all that when i host a system link lobby and try to join it from my other xbox it doesnt show up there.

ah h common mistake you nuddeeee~! put your mw in your jtag go to your disc drive on xex menu and then copy default.mp.xex and place it into your mw2 directory and then it will say do you want to replace this crap say yes and then you want to go back to your disc drive copy default.xex and then paste that into your directory and overwrite it and make sure every .dll is deleted and no patch.mp.ff is in or it will not run correcctly now once you have done that take your droseum20 or what everpatch your using and copy the dll and paste it into your directory and than paste the default . mp.xex in it and then ALSO make sure your retail xbox and your jtag are PLUGGED INTO YOUR ROUTER . go to two internet cords in your house where there it internet connected to both ends and connect your jtag go some where else and do the same with your retail start up your mw2 put xbox live unlocks on onto your system link and vaioula ! you have just been given the ultimate tutorial! HOPE IT HELPPEDDD:D
