I think success of emulation can't be guaranteed. One say it's perfect, the other says it sucks. I'm not too impressed with emulation. Tried WinUAE (always the newest versions) on a variety of PC hardware (Duron 750, Duron 1300, Pentium IV 2000 GHz, Pentium IV 2.4 GHz, Xeon 2.8 GHz) and always ended up somewhat down. While some games work rather well, using software like OctaMED really doesn't do the experience any good. The time between pressing a key and actually hearing the sample seems to be hours where as I can't recall such behaviour back in the A500 or A3000 era (note, the A3000 was at first just a 16 MHz 030).
Probably it's just me experiencing this behaviour, that's why I've asked a few times if this is also true on the MiniMig.
