Move your Habbo.swf to the rabcdam folder then, make yourself the following batch files and place em into rabcdasm folder:
Decompiler.bat
Code:
abcexport Habbo.swf
rabcdasm Habbo-0.abc
rabcdasm Habbo-1.abc
Compiler.bat
Code:
RABCASM Habbo-0/Habbo-0.main.asasm
RABCASM Habbo-1/Habbo-1.main.asasm
abcreplace Habbo.swf 0 Habbo-0/Habbo-0.main.abc
abcreplace Habbo.swf 1 Habbo-1/Habbo-1.main.abc
pause
When you want to edit actionscript you simply run Decompiler.bat and you get the editable files, you edit them and then you run Compiler.bat (some tutorial stated that it's good to run it twice just to be sure it works), then make sure that Date modified is right on your .swf so you know it really worked, then just place .swf to your /r63, delete cache and enjoy. :D
