Running a Metin2 private server is a and copyright law in most countries (code is proprietary). These files are for educational and private study purposes only — do not host publicly for profit or large user bases unless you own the rights or have permission.
If you are starting out, download a "Vanilla Clean" source file rather than a "Super Re-pack." Learn to fix the bugs yourself before trying to run a live server.
If you have a specific question or topic related to Metin2 server files, feel free to ask and I'll do my best to help!
