So, when I think "emulation" I usually consider it to be software emulating a hardware device (e.g. the original Gameboy, audio cards for legacy programmes that required audio cards, etc.). What they're describing in the article is what has been described to me as being an abstraction/compatibility layer. So my questions are: 1.a. Is that really what this is or is it actually an emulator? b. If the latter, what makes it an emulator rather than a compat layer? 2. In general, how much do the two concepts interact? E.g. separate concepts entirely, ends of some continuum, etc.

The hardware being emulated here is the CPU.
