[Java] V9 server help (packets/headers/etc)

Hey all,

I have never made a server in Java before, and to be honestly I am just around the corner as a Java beginner. My first unfinished game is a 2D Minecraft like-game (easy one). Ever since I saw Blunk V5, I wanted to make my own V9 server. This is because there was never a finished server for V9, V13 or V14. There was always a development thread about those servers, but they always died. I have been waiting to long to see someone coming up with a V9, V13 or V14 server with Java & MySQL. Even if I saw the Retro scene growing in 2006, I never really went into coding when all servers were still made in Visual Basic 6. Like Flex, Genaga V9, USA111, etc.

I want to make my own completed V9 server with all features that were available in version 9. Except BattleBall, SnowStorm, Wobble Squable and Camera this can be added later. I need someone who can help me out where to start. I have a lot of free time and I want to make this server for fun, because version 9 was a pretty awesome classic version. The catalogue loading speed was good and all furni was still stored in a file. Rooms loaded faster in my opinion. Can someone help me out with this?

Thank you!
