According to a previous thread I exchanged with Anders Eriksson : [hatari-devel] First 68060 demo running from beginning to the end
According to Anders, The demo Eskimau uses intensively the FPU.
This demo works with hatari (slowly of course and with a distorded sound), but it works from beginning to the end.
There are some graphical glitches in the tridi mapped screens that may be due to the FPU code in hatari.
Another point: When I was working on Magic emulation, it seemed that there are some registers specifics to the 68881/68882 that are not present into iomemtabfalcon.c
Maybe we could add them, like for the DSP, by testing if the FPU is present or not, and adding/removing them in the iomemtab table ?

Btw. According to this mail:
At least in Aranym, the FPU emulation is "broken", not just
non-cycle accurate. I wonder is WinUAE emulation any better...
