SWF decompiler tells you all what you need.But how do you figure out where a specific portion of the code is in the memory?
"Raw data" can show not only decompiled string (e.g. function names), but also binary data as-is. Example:
Now you know that the "_as3_iftrue offset: 6" is "11 06 00 00". Next, use "array of byte" search in CE.
(I found another function, but it's clear as example)
