You can find the line and re-write for yourself if you know reverse engineering well or you can try more and more until which one looks good for you. In my case, it's better to find the line with reverse engineering. - Jodie

I guess you removed libserverkey folder in your source files. You just need to do the same things in Makefile (in game/src folder) - Jodie

Actually, you could try this or you could try to fix that. Problem relates to libserverkey. I think you removed it or Makefile can't find it. cd /yoursrc/game/src && gmake clean && gmake - Jodie

This command will be unsuccessful if you don't have enough space at your inventory. - Jodie

Do you know reverse engineering? Post the old executable file (metin2client.bin) if you don't. You can try to reverse engine to the executable file to find the right things for move rotation if you do. The last chance is you have to try which one looks good for you by yourself. - Jodie

It seems like Knight Online. I think this method is often using by Webzen. (For example; Expanded Inventory) but I liked the idea. Keep going! - Jodie

That command will be enough for you if you wrote this command. (portsnap fetch extract) - Jodie

It seems like you don't have cryptopp. You can use Extern folder for this job or you can install it. I think it should be like this cd /usr/ports/security/cryptopp && make install clean - Jodie

Is your game file stripped? You can't see anything if it's stripped. - Jodie
