This is a guide that I use. but to break it down easily,
1. Zackdeaver's translation project will be your data folder on top of the KRO data.grf and rdata.grf
2. Clientinfo.xml or sclientinfo.xml will be the file to configure which server your client will be connecting to. that file will be inside the data folder.
3. Use Nemo diff patcher to configure your actual .exe file to however you wanted it to be. Diffs mostly depend on your client version/date.
4. Big tip, while googling around for steps on how to set up your server and client. Try to understand how it works rather than following steps blindly, this will give you a better understanding on how the emulator works and how you can customize, troubleshoot and handle your emulator better.
