I dont know how to explain it any simpler...
Browse the memory region.
IN the top box (The assembler)
Right click on the address bar at top.
Search for "005D91DE" in the assembler.
Select change register at this location,
Then click the ZF box.
After its selected close the memory editor
And THEN make the " Mag feed active"
In the lower left box.
(Note its marked already in the pictures , but the cheat should not be activated until after
selecting the ZF box)
Thats all there is to it. Cannot be done in lobby, MUST be done in game.
