Here's some previously unreleased information
on 68000 instruction timings:
I saw this too, it's quite interesting.
Since the motorola's US patent is available since some time, I think
most of the timings used in WinUae "cycle exact mode" are already
correct and similar to this doc, or tested against real hardware.
In the case of the old UAE cpu used in STF/STE emulation for timing
critical operations (raster, fullscreen, ...), it could be useful to add
some special cases (prefetch behaviour are sometimes a cause for some
failing games protection in Hatari).
