Resources

Here we list decompiling resources which you may find useful.

Intel Instruction Set Manuals The main page for these manuals has gone, and this FTP site will surely follow. Get them while they're there!
PeReader We use this excellent, solid and reliable disassembler from Frediano Ziglio to dump the raw assembly code. We have improved it in-house and released our source code back to the project. We highly recommend it for x86 disassembly projects.
Decompilation on the Re-engineering Wiki - This great resource on decompiling will tell you a lot about the history of decompiling and other related topics.
Here is the page about this company
VBReformer - You will need this program from our partner site, which allows you to recover all the Forms from a Visual Basic program. They do not yet offer code recovery - you will have to come to us for that.
The Boomerang Decompiler - An open-source project which is being developed to decompile C and/or C++.
IDA Pro - A commercial disassembler sold by Datarescue which is very successful and very advanced.
Papers on Decompilation - This link from Google Scholar will give you a lot of papers about decompilation, although you need to have enough academic knowledge to understand them, or have to pay for the resources.
"Help, I've Lost My Source Code" - A guide on recovering source code, how much it can cost, and what you should provide. Note: This guide does not always apply to our service, which is fully automated, requires only OCX files and is a lot cheaper than "$15000 per man-month".
"VB Decompiler Native and PCode" This company offers a PCode decompiler, but for native code, there is only a disassembly at present (not decompiled source code).
"Visual Basic 5/6 Decompiler" This company offers a decompiler for native code programs. We have not evaluated the quality of it, and last time we checked, there was a maximum filesize of 100kb. Feel free to try this out before using our service, although we don't charge to send you a sample of decompiled code from your program.
