This tool takes the work out of pre-hacking games.

It doesn't crash half as often as sothink either but getting used to it takes some time... Especially when searching, as you can search in every part of the window (you can't search everything at once either), you may search in the wrong parts by accident.
Big disadvantage is that it may get stuck decompiling something without any indication of it freezing or just opening something large... It needs to decompile every part each time you try to read it as well, doesn't store it into it's memory.
It's incompatible with the raw data AOB extractor but that can be solved using the replace function of most text editors (replace ; with //).

I love that this thing jumps right to the hex code that you are interested in, and you can view it side-by-side with the (pseudo) actionscript.

However, does anyone have a problem where it suddenly gets very graphically glitchy and requires a restart?

I guess I should really learn how to use this thing then. I can find and make aobs in as litle as a minuet with cheat engine, but not everything is that easy to find with it.

This is a very nice tool. The deobfuscation works as a charm, but as far as I can tell, the new method (for pre as3) does mess up the bytecode in such a way that using the deobfuscated bytecode as a template results in aob's that are nowhere to be found. It does greatly improve readability though. ^^
