I found this on se7ensins

Required:

- A JTAG'd Xbox
- .FF Viewer (download HERE)
- A transfer cable

Step #1.
After downloading .FF Viewer, you will be presented with the following window. In it, press "Open and extract .FF". Locate your Patch_MP.FF (if you don't have one: look in the "defs" folder)



Step #2.
After opening the Patch_MP file, click the little "+" on "GSCs"



Step #3.
In the GSC list, single click on "_missions.gsc" which will open the code editor.



Step #4.
Inside the code editor, press Ctrl+F or Right Click->Find and inside the "Find" window, enter this:

self waittill( "spawned_player" );
Copy that exactly.

It should go to the first occurence of that string in the file. (it should be around "onPlayerSpawned(){")



Step #5.
Next, add your modifications to BELOW the line that you searched for. Explained in this diagram. The little circle is the "Insert" menu. Use this to add mods like wallhack, killstreaks, score kills deaths, etc. all from 1 menu option!




Step #6.
Press the button marked "1" on the image, and then go to number "2". Note: if the program complains about the file being too big. Find comments (usually indicated by the characters "//" or "/*" and "*/" without the quotes) and delete them


Step #6.
Copy the newly edited Patch_MP.FF into your MW2 folder (usually on your Xbox's HDD). If you do not have a patched default_mp.xex, download it HERE. And now you have modifications of MW2!
