1. Know and understand UDP packet protocol(commonly used in games)
2. If you dont know what a packet is then forget even trying to learn.
3. Bridge your PS3 connection with your network
4. Get a packet viewer program such as wireshark or commview to view the UDP packet data.
5. Make a packet handler for the computer to store packets and send them when needbe.
6. Play around with the packet data and re inject it to see what you get.
if you want to try google type in "ps3 packet injection" but that wont really help you.
