Cushypen Patcher

// Usage: Command Line only, put all your cushypen rips into a folder, give it that folder's path and then it will patch all files in that folder.
// For example: CushyPatch.exe "C:\AllMyWeirdPorno" will take ALL files in "AllMyWeirdPorno" and patch them. If they aren't an image it will crash most likely, there is NO error checking and it's quick and dirty, works if used properly.
