You have those A2000s now, why are you messing with WinUAE when you have the real thing now?
Sorry to hear you are struggling with WinUAE, but it is usually just a matter of getting it set up correctly.
I have not played the Bards Tale or too many other games on WinUAE. I have real Amigas for playing games on.
I hope someone else here can help you, but you must be specific with what settings you are using, and what problem you are seeing.
