Yeah I'm very familiar with 'file', I just wondered in what context one needs the ability to identify 38 machine languages, i.e. why does an organization deal with files containing unknown machine code, and have the need to identify them?
Sounds like maybe reverse engineering/security "research"-oriented work, perhaps.
I was basically leveraging my eidetic memory of opcodes and operands and its bitfields.
It all got started with writing pure assembly for Motorola 6502 (for arcades) and PDP-11 then eventually ended with ARM/RISC/MIPS. Most esoteric one is the Transmeta VLIW (TMS3200-02).
