True, APUS doesn't require byte swapping. But I don't see how this
makes it hard to integrate APUS.

This is a valid concern. I don't know if it's possible to do anything
It may be the case that none of the Amiga drivers use the same IO
macros as other drivers use. As I remember it, there are two set of
macros. But it's a long time since I looked at that, I could be wrong.
