Re: [hatari-devel] 060 + DSP -> freeze

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

The patch is ok, (tested with Starstruck demo again ;)

A little thought : as cycles all take 1 cycles in 68060 mode, would it 
be possible to run faster then 32 mhz only for 68060 to have a faster 
CT60 emulation ?)

Laurent
