There are quite a few threads of how to do it, but I was never able to figure it out. I was able to do some stuff in the past, but it has been about 10 years since I have done anything with the structs.

As for finding the op codes, I think it is more of being familiar with the packets and what to expect than anything that is really able to be taught. I could be wrong, but that is what I kind of remember. I was pretty much told to go to a quiet zone and repeat an action over and over until you find the correct op code.

I recently started playing again, I dont know for how long, but I did notice that the spells are messed up.
