EDIT : FIRST METHOD I POSTED WAS BUGGED (i wasn't playing with it)
This one should works. Sorry.
Yes, there is an embedded Google Analytics tracking system in all ROTMG swfs since... i can't remember.
Since i dont like to be tracked, i disabled analytics urls in my host file but it gives some big and ugly debug messages in Vizzy
I found an easy way to totally disable it
1) Look for an "_-".asasm file containing
"tracker") type QName(PackageNamespace("com.google.analytics"), "GATracker") end
Its a trait slot.
2) Make sure the following methods do nothing by add "returns" to the code
* pushtrue returnvalue for "trackevent"
* returnvoid in the method which is calling trackPageview
3) And... Now in GATracker.class.asasm
* pushtrue returnvalue for "trackevent"
