[AS3] memory of game falsh

see this code:
{
_loc_2 = Object(event.target.content.getChildAt(0)).content LoaderInfo.bytes;
L.unloadAndStop();
L.contentLoaderInfo.removeEventListener(ProgressEv ent.PROGRESS, this.Loading);
removeChild(this._C);
removeChild(this.MadeBY);
Replacer = new BytesReplacer(_loc_2);
Replacer.FindSwfFiles();
Replacer.ReplaceOnce("a0 ab 96 12 01 00 00 47 d0 60", "a0 ab 96 12 01 00 00 02");
Replacer.ReplaceOnce("29 d0 d0 60", "29 d0 d0 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2");
Replacer.ReplaceOnce("d0 30 5e ?? ?? ?? 68 ?? ?? 60", "47");
Replacer.ReplaceOnce("d0 60 ?? ?? 66 ?? ?? d0 61 ?? ?? d0 60 ?? ?? 66", "10 70 01 00");
Replacer.Add("d0 30 20 80 ?? d5 60 ?? ?? 60", "47");
Replacer.Add("d0 30 20 80 ?? d5 d0 66 ?? ?? 60", "47");
Replacer.Add("d0 30 d0 66 ?? ?? 5d ?? d0 66", "47");
Replacer.ReplaceInAllSource();
_loc_2 = Replacer.GetBytes();
LoadBytes();
}

*********************
I wonder
example: Replacer.Add("d0 30 d0 66 ?? ?? 5d ?? d0 66", "47");
that he is going:d0 30 d0 66 ?? ?? 5d ?? d0 66
for: what value?

sorry if this is an absurd question...
as3 do not understand anything

I never heard of BytesReplacer before.
