From what I know, 486 has six more instructions compared to a 386.

My question is, can't each of these instructions be simulated by
a set of 386 instructions such that the functionality is not lost?
This way we just need to write a parser which will go through
the 486 specific executable file looking for these unique
instructions and replace it with the equivalent set of 386
instructions, thus producing a 386 specific executable file.
