I have a project that I am trying to fix from a guy that left (let go) from my company. He has violated every fundamental principle of software engineering, not using sourc
I've used RecStudio (rec22) and IDAPro to try and decompile a C++ project, together they probably wouldn't have been enough to do the job I had except that I worked out the demo project the program was based on so they gave just enough info that I could make something like the same project again.
In the end one other thing I was doing was compiling code that I thought matched and checking that I got the same result in the decompiler.
Good Luck.
