u going to make an "edit dd.gsc file" video?

Well after working hard to get a Modded Patch created by myself working. I decided to make a simple application that can help you create your own modded patch. Just unzip the MW2PatchMaker.zip into a folder, and put your PS3 Original "patch_mp.ff" (Altough I included a BLUS30377 patch there), and follow the instructions.
