If U don't mind my asking-which version of WinUAE, & was the sound enabled?
I haven't budged from using WinUAE 08.8r8.
I've tried the 08.14 versions but they seemed far slower & the well documented choppy sound issues.
Granted I've only got a lowly Celeron 266 myself, so I until I'm able to get a major speed boost I don't think I'll be bothering with WinUAE 08.16 r4 or later somehow!!
