Java - v9 - HSR - FuseServer

[Noelle]

What is FuseServer?
FuseServer is a server written from scratch in Java, written to support the FUSE technology (developed by Sampo Karjalainen and Aapo Kyrölä). The server supports v9 and v9 only. Versions above it will PROBABLY not be supported. The goal of this project is to write a complete v9, including camera, battleball and something secret I have in mind.

Why Java?
Because Java is crossplatform, and since making camera in Java is easier than in C#.

Based on?
Completely written from scratch.

Code snippets:

public class UPDATE  implements IMessageHandler {

    @Override
    public void handle(GameSession session) {
        //@l@D@Y8420118001270012900121001@F@Cbla
        TMap<Integer, String> userPacket = session.getRequest().decodeUserPacket();
       
        String newFigure = userPacket.get(4);
        String newGender = userPacket.get(5);
        String newMotto = userPacket.get(6);
       
        if (newFigure == null && newGender == null && newMotto == null) // no updates, useless to continue
            return;
       
        if (newFigure != null) 
            session.getHabbo().setFigure(newFigure);

Looks promising! Carry on, and eventually one great emulator will be released! Best of luck.

 

[Kristopher]

Any updates?

 

[Manuela]

Seems quite good so far, we'll be waiting for updates.

 

[Noelle]

Sorry - I actually forgot this, also, exams are a pain in the ass, updates will come once a week or twice if possible. Until Christmas break

Also, one big update video:

 

[Syntus]

Looks good love the old times!
Keep it up!

 

[Noelle]

Sorry for the lack of updates ~ they'll come soon as I'm simply too busy with school exams.

 

[Genaga]

Ahh v9, I remember it well, if you need any help with it.

Let me know!

 

[Chrobens]

This is quite possibly one of the best development threads on here, don't give up with this, would love to see some V9 come into the mix!
