Packetlogger programming question

Hi, I want to learn to code my own packetlogger for nostale and understand the code.

What I need to know ?
I only know that I will need to know reverse engineering and programming memory-read/write programs.

But where I need to start ? What I should find ?

I don't want any code to copy/paste, I want to learn.
I am trying to do this for like a year and I cannot find a response to my answer.

Thank you for your time.

Sorry for my english.

Find the function(in game code) that is called every send/recv packet and has the plain packet(or spilted array) in registers, then hook it

You need a disassembler/debugger, programming lang (pref c++) to make the DLL, and hooking a func. using detour.

PS. And a little of ASM too.

ARM not needed. Wtf?

x64dbg/IDA, C/C++, ASM knownledges and RE basics.

I advice you to look for Lena's tutorials (the firsts at least)

ASM, not ARM, true (I was debugging an iOS binary and got cofused)..
