CHIP-8 is an example of a virtual machine. While virtual machines are great for learning how to program in low-level languages, virtual machines are abstractions that tend to obscure the hardware of the actual machines they run on. The more popular virtual machines have been reimplemented on many host architectures, and implementation details often leak through and cause incompatibilities on different host systems. See this comment in particular: https://github.com/mamedev/mame/issues/9246#issuecomment-1028161396
MAME generally does not emulate virtual machines themselves. However, emulating any actual piece of hardware that runs a virtual machine is entirely within scope, even if that hardware was custom-designed for that purpose and no other.
