Agreed.

Excellent idea! This is a classic use of Forth to break "encryption by
obfuscation" ;)
I was thinking about a "virtual 80x86" machine that could single step
through the BIOS ( or driver ), filtering out highlights such as I/O port
access.
This sounds similar to your dis-assembler/assembler combination, but without
the need to assemble...
There would be less manual interpretation of the code, just run through it
and see what happens.
