Emulators support nearly everything. I can even run a TI994a program on a PC, Mac, or Linux. If you can't run emulators on Mac that is sad news to me. Maybe bad example, it was technically 16 bit, but it was well over 30 years old. Here is a pet emulator: https://www.masswerk.at/pet/

Just the other day my brother told me he met a really talented graphics designer that still primarily uses some 25 year old sign design software. Never heard of it before, and don't remember the name.

We balk at having to pay monthly for software we bought over 10 years ago and even today we'd not miss any new features offered. Great artists (I'm not one of them) can produce great visuals. Limitation can be better for creativity than no restrictions for some anyway.

Of course you can run emulators. But that has nothing to do with OS vendors maintaining backwards compatibility.

Are you really arguing that Windows is compatibility with the Super Nintendo because you can run an emulator?

Yes, and this is how powerpc applications were supported for years.
