Logging packets from official conquer or trial/error.

Personally I noticed that the most up to date (packet logged) attack packets had in used bytes. I figured those must have to do with new features so I filled them in with values based on a command and figured out all the effect subtypes.

You can also reverse the client and grab valid packet types' structures and valid processed/sent subtypes, as well as other information.

^ This makes trial and error so much more efficient, since you'll know the size and type of the packet (including the field sizes and where they're located).

Trial and error is good idea but i think i takes alot of time

Not really. 5-10 minutes usually. You don't structure entire packets, you use logged packets or client as a way to know the general strictures. From there you use trial and error to fill in unknowns/test subtypes.

Look at any one of the many guides I and others have written on this forum to apply your programming knowledge to conquer. If you dont already have programming.knowledge then read some.ebooks or from Google.
