WinUAE 1.6.2 beta 6 is easily the best Amiga emulator available for Windows. This update has these changes since the last Win UAE 1.6.2 public beta:

Beta 6:

- STOP increased PC only by 2 if trace was active (copy protections..)
- WASAPI exclusive mode improved (final Windows 7 SDK had much better examples than RC or Vista versions)
- restart sound (close and open) if sound gets stuck instead of killing sound completely
- thread priority updates and fixes (perhaps this fixes reported slow filesystem emulation)
