Exactly. In BasiliskII/SheepShaver jargon, that's called an "EmulOp". And
purposes cover native driver hooks (e.g. audio, ethernet), copy/paste,
Native QuickDraw acceleration, host file system access, etc.
However, this kind of optimization is specific to certain systems as you
would need to either run-time patch the OS, or provide necessary drivers
with those hooks compiled in (MoL).
The problem on x86 side is to find out a particular instruction sequence
that is not (and won't be) meaningful.
