^I'm done. I can get it working already.
Duhhh, dude. Have you ever use ur brain to think whether the size of the client is big or not? Every time we dislike a server then we must redownload new server file client (800mb could be more thou)?
More, what happen if the server we downloaded for 800mb SUCKED than we expected?
Not all people got 10 MBPS internet speed, alright? Downloading the client could take more than 8 hours.
Please don't tell people what to do when you don't even know the correct consequences.
Anyway, I don't feel like entertaining kids further so..
How to get it working from Dekaron-Extreme client to Fussion:
1) Download the launcher from saybot11 (CREDITS GOES TO HIM!)

2) Paste it into Dekaron-Extreme folder.
3) Open WinHex and load data.pak
4) Search for Dekaron-Extreme IP (should be got 3).
5) Replace the IP with 75.127.124.92
6) Save and done, you can login to the server already.
