Somehow I think using a normal calculator would be faster..
So i decide to make a program that updates teh addresses for mw3 about an hour ago and 14 minutes ago this appears interesting.
Ignore my message about the offsets shifting by 0x80, I think that's only for some stuff, not everything. :3

How use this:
0x63, 0x61, 0x72, 0x64, 0x69, 0x63, 0x6F, 0x6E, 0x5F, 0x65, 0x6C, 0x69, 0x74, 0x65, 0x30, 0x32, 0x00 [From Modern Warfare 3 Source Code / Address Thread]
...
"In the Input Box you put all the addresses you want to update. (Not with the 0x, &H etc.)"
