PPF patch problem

[IWannaPeeOnADuck]

I recently bought Ridge Racer V from the Family Video Mart. They were selling it because alot of people were complaining about how it didn't work due to scratches. I tried it and, sure enough, it doesn't work. My CD ROM reads it fine, but I heard that games that are out for rent have a different copy protection on them! Is this true? The PPF or PFF or whatever they are patcher says it is a different type of BIN and PPF. A little help here please??
