According to DefineFunction2 spec the flags define what is already preloaded to some
registers. But Ffdec doesn't resolve them and the code looks like
function init(Void)
{
register2.init();
if(register1.preset==undefined)
{
register1.boundingBox_mc._visible=false;
register0=0;
register1.boundingBox_mc._height=0;
register1.boundingBox_mc._width=register0;
}
register1.useHandCursor=false;
}
whereas it is possible to be more precise and make it more meaningfull.
"Next, the preloaded variables are copied into registers starting at 1, and in the order
this, arguments, super, _root, _parent, and _global, skipping any that are not to be
preloaded."
DefineFunction2 "" 1 3 false false false true true false false true false 0 "Void"
PreloadSuperFlag, SuppressArgumentsFlag and PreloadThisFlag are set to true. Thus it is
quite clear that register1 is "this" and register2 is "super".
Hi,
I know about this.
This was already implemented a few versions ago before I updated the deobfuscation
algorithm. You can download older version(1.4.2u1 should be OK) or wait till I release new
version.
