hyper64 and micro64 are different things - the later is highly accurate 
(comparable with VICE).

i tried the emulator, but never checked for this behaviour .... i just 
remember bero mentioning it, iirc it also can output sound based on 
rasterlines instead of frames, which allows for much improved sound/video 
sync.
