If Robbolito code was composed from a bunch of open source engines, it would
have a much better reputation in the community. As it stands however, the
webpage says that it is based on the disassembled code of commercial engines.
In addition, the readability of RobboLito's source code is in question as well.

Sorry, I was just interested why it does not work on Scid. I didn't expect to
open a can of worms.

Of course this it possible. But you won't get constant expressions and
variable names.

I don't think any assembler can add information that given variable holds a
number of white knights.

I fail to see why people accept without any proof that somebody can just take
the disassembled, unstructured code from a few engines (without any code and
documentation) and merge it, achieving a better performance.
If this was that easy, why not take a bunch of best Open Source programs and
merge them, creating the best open source engine? That should be much easier,
right?
