The biggest questions are going to be:

	Is the software 32-bit clean?  Much was, but much wasn't.
	Dungeons of Doom wasn't, for instance.

	Does the program try to access the hardware directly?  Some real
	old programs not only write directly to the screen, but they even
	use hardcoded addresses to do so.

	Does the program self-modify?  In 1985 it was relatively safe to
	self-modify, but that's not the case with a 68040 with the cache
	on, or with Executor's synthetic CPU.
