Hey man I got a couple questions about this. and I'm gonna go check out Johnny's post after this which may answer my question.

Anyway, I heard about these hacks and I have several different game saves with the hack codes. I did exactly what you said to do, and everyone else says to do. However the hacks never work/do anything.
I delete/ overwrite the saved data for COD4 but then when I start a game nothing happens. I noticed that somehow a "regular" saved game file shows up and I'm assuming this file over-rides the one with the hacks.
Now, in the game data utility there is a COD4 file that has the 1.30 patch for the game. Is this file interfering with me being able to hack? Should I delete this file?
I have heard, when I first started to investigate this COD4 hacking stuff, that the hacks won't work with the patch and there was a tricky little thing you could do to bypass the mandatory 1.30 patch download. But now I see a lot of game save files that say it doesn't matter if you have the patch or not.
Can anybody shed some light on this for me?
