3) Compatibility is MUCH better for these nice old games and utilities from the early 90's. I'm having a very hard time running certain utilities in WinUAE, even though I configure it like the real machine. When I run it on the real thing with the exact same setup as in WinUAE, the same software that hung every time runs perfectly every time. This might of course get better with time.
Hard to fix anything without names of programs.. (and I haven't heard about non-working utilities for a long time so I really suspect the reason is something else than emulation accuracy..)
