NOOOOOOPE! Not that tut! That is what I did and my client was not running. For anyone that needs a good tut here is one http://metin2tech.de/topic/19-cyang-limit-erh%C3%B6hen/.
Of course some parts from the hungarian tut are better (ex. you should do llPrice not dwPrice) and of course in the hungarian there are some more details on what you should change but for everyone who is about to go through this procedure I recommend the german one as a "core-tut" let's say it that way and as a secondary tut for completing incomplete parts to use the hungarian. And don't forget to change the python parts! I did the german and now I have problem with my Inventory only (does not go higher than 2.124.000.000) but if I find any fix for that I will mark it with a "Like this" so you can go to my activity and see how did I fixe it. I hope I was helpfull
EDIT: Problem solved (only visual, still needs some stuff to work properly) - See comment of @.T4Ump
