Re: .EXE -> .ASM -> .EXE

Is there much a need for re-assembly these days?...

Yes:

* There is a huge difference in between a disassembler that
can re-assemble, and one that cannot do it, that is that
the first one can be proven right (or wrong) with one click.

* The very first purpose of RosAsm Disassembler is about porting
C Demos to Assembly. What was consuming, say, one month, before,
can now be done in one or two days.

* One of the purpose of a Disassembler is in the educational
area. Learning from a faultive disassembly is not a very
good idea.

* Maybe you missed it, but this (one another) attempt of aggression
driven by Master Pdf, is based on a request from a CLAX participant,
and, as long as CLAX is moderated, he cannot post such attacks
against RosAsm, there. The question was from a guy wanting to
improve an old app he had developped (maybe a big lie, but well...)
... Such case may also exist, that is, you write an App, loose the
Source, and therefore, may be happy if a tool can do such a job,
for which, evidently, nobody (but Master Pdf, of course), would
ever recommand IDA.
