Any more EMU updates you would like to share ? :)

[Quackster]

Switched to Java and working on Neutrino's build again. Because there are way more headers I can use

Snippetz?

Quickster which cms do you use for sierra and could you send the download link for it?!

[Disguised]

He uses SierraCMS. It's currently on Github @ http://github.com/QuacksterNET/SierraCMS :)

[P Lambda]

Another change.. *sigh*

Will THIS be completed, or will you change version/language in a few weeks again?

[GertJanA]

He has made some big progress in the time of Sierra.
And i think he will keep it this name now. And he will just make the best out if it. (I think).

Greetz,

[Livar]

Not Java again, you all may think "but java is the best language for a habbo emulator" yeah well, reason being said is, alex's strong language isn't Java (i heard indigo was for practical reasons aka trial and error).

should finish it off in c# then port it over...

[Nathandj]

Finish the C# one, then re-write it in Java.

[Livar]

Finish the C# one, then re-write it in Java.

Or just port it over?

[GertJanA]

I question left.
Does the DB structure have the same as Phoenix / UberEMU?
Because that would be nice for users who used Phoenix before. So they can just run that emulator. With some other tables and BAM.
Hotel running again. :p

Greetz,

[Zak©]

Are you sure it's just because of headers?

You can just copy the header id's?

[Quackster]

I'm finding it hard to find time to work on this development. Sorry.

[Zak©]

Is that why you switched to Itach's emulator.

Or are you stopping?

Java is a ram hogging bastard.
