I want to find the packet send/recv hook addresses so I can make a packet editor/spammer for my game, but I'm not sure where to start. The experience I've had for packets is writing a C++ trainer and send a few packets via send/recv hooks, but only with someone else's discovery of the send/recv hook addresses.

Does anyone know any tips or links to guides on how to start looking?

Also, looking around on Google, I see a certain language being used a lot when dealing with packets/socket stuff. I think its name is Delphi (?). Is this a good language to pick up? What kinds of things is Delphi good for?

Thanks in advance.

Use a debugger and find send / recv calls inside the process. Then from there backtrace the calls that use them to locate the original function you want to hook onto; whether it be the actual games function to send packets, or to hook somewhere earlier such as the encryption and decryption functions so you can manipulate the packets.

For starters, Cheat Engine is written in Delphi. (With some bits of C and such.) Everyone has their opinion and preference for which language to write in so it's entirely up to you if you want to learn it. C/C++ is more than enough to do what you want though if you already know them.
