Know a good disassembler?

jacobjordan

I am looking for a free disassembler, preferably not a command line one. I couldn't find one on Cnet, and i was wondering if any of you know of one.

if (your.Life == Lifestyles.Programming) { your = Cool; } else { your = !Cool; }

for .Net?

Disassembler, not decompiler. No, not for .NET. I don't think there is such a thing as a .NET disassembler. A disassembler translates normal programs into Assembly language, a Decompiler will translate it into source code, which is really only possible with .NET programs. I am looking for a disassembler that will disassemble normal programs.

if (your.Life == Lifestyles.Programming) { your = Cool; } else { your = !Cool; }

You can get a free disassembler here[^].

Like Richard said, Olly Debugger is a great piece of work. You could also look at WDasm32[EDIT: W32Dasm] or IDA Pro. IDA has a plug-in module that will decompile code back into C source. It's a 2grand plugin that still seems like it should cost more. There's also a number of programs available for things coded in languages other than C. You can find VB Decompiler in both Pro & Lite versions, also there's "Delphi and C++ Decompiler" You should also be able to find links around for a copy of Sourcer, though I don't recall them having a trial copy.

It is w32dasm, actually. I second that.

I just saw they updated their tools and most of the issues I had are gone now :) Now to figure out how to utilize it :rolleyes:

xacc.ide - now with TabsToSpaces support
IronScheme - 1.0 alpha 4a out now (29 May 2008)

Nah sorry, nothing helpful.

I've heard of IDA before. I just fould IDA Pro on Cnet, it says there it is $470.00. Are we talking about the same software?

I have tried the Delphi & C++ decompiler, and it's a joke. I have also tried the lite version of the VB decompiler, and i wasn't impressed with that either.

if (your.Life == lifestyles.Programming) { your.Cool = true; } else { your.Cool = false; }

Dunno to be entirely honest. I find dial-up + CNET = me.frustrated, so I don't visit there. That price probably sounds about right for IDA. In case you didn't know, it's now developed by Hex-Rays, the maker of the $2000 plugin I mentioned before. If you visit IDA's homepage here: http://www.hex-rays.com/idapro/[^], you can download a free version that's still pretty bloody impressive. What's the target app compiled with? I may well have a better solution for you.

Hehe, Olly was always awesome :)

"impossible" is just an opinion.

http://www.hex-rays.com/idapro/[^] IDA Pro is gold, it even gives you the option of replacing code inside functions or even adding functions, which opens the door to a whole lot of nasty hacking fun. search for the 4.3 version that was still freeware

IDA is the best. It's worth paying the price if you find yourself frequently needing to disassemble...

In 25+ years of professional software development across a wide variety of markets and a broad range of machines and operating systems, not once have I found a reason for using a disassembler. Unless you're a thief.

I've been using IDA Pro some time now (at least 4 years) and I'm even more happier with the HexRay decompiler. It is worth every cent of it.

There can be some very good reasons for using a disassembler, and not just for thievery. Personally, I've used the copy of IDA Pro I purchased to reverse engineer and understand some legacy Motorola 68k hardware, debug a flaky RS-485 card driver, and decipher what a number of vague error messages meant when returned by various win32 api calls. Also, think about what you would need if you were writing your own debugger or disassembler. I would think having a reference disassembler would be a very good idea. Disassemblers are tools that can certainly be misused, but one really shouldn't assume that will always be the case.

The Reflector is the best .net disassembler. It shows you the code in C#, VB, C++.net and Delphi.net, and it has utilities (separate exe) to open resource files. You can download it at http://www.aisto.com/roeder/dotnet/[^]

So what are you accusing me of exactly? Your claims of experience do not impress, there are many valid (legal) reasons for needing to use a disassembler. You simply need to broaden your horizons to find them
