Liar.

Feel free to show any Link to a Post of mine, where i
would have written that RosAsm Disassembler was going
to disassemble and Reassemble all Applications in two
Clicks.

True. More than this: This is unhonest illusion selling:

"The Disassembler fails to do the job. Solution: Let us
let the user do the job, instead". Absurd.

With Small Apps, a Disassembler must be able to produce
a 100% valid Disassembly Source from most Files. In the
case of RosAsm Disassembler-Reassembler, there is no need
of the so called "Interactivity", because the user can
modify the Source, by hand, in case of minor errors, and
in case of complete failure, there is no hope, anyway.

On middle size and big size apps, either the disassembler
is able to do it all clean, or not. In case not, there
is no hope that the user could be ever able to do better
than the Disassembler Engines. And saying the reverse is
nothing but lies and swindling, given the demential work
that the user would have to do.

No. It will much probably be, for you, the exact same
thing as with the HLL Pre-Parsers... With an IQ under
80, this is not easy to understand...

:))

Though for the Users and for the Developpers of the
Disassembler, the way this "bit of Interactivity"
is implemented will be really much helpfull, for
two purposes:

1) Speed-up the Multiple Disassemblies of a same File.

2) Force some Recognitions in a simple click, in order
to experiment and understand where and why an Automatic
Recognition was wrong. Accessory, it may even achieve
the work promissed in vain by the so called Interactive
thingies, with their illusions selling, probably in the
case of middle size applications... To be tested...

Could anybody have any doubt about this point?

After all, aren't you the definitive idiot who
claims every nbow and then that "RosAsm Symbols
Table is broken"?
