Why old UAE core emulates by default something which
isn't standard on 030?

Thanks, I missed that.  I was in hurry to be somewhere
else when I noticed the issue (I had first thought it
was EmuTOS regression because I've naturally tested
earlier EmuTOS versions only with old UAE core).


IMHO it would be better to add something about that
at least to the compatibility list.  These kinds of
differences between our emulation cores can be a bit
surprising...

Are there a lot of demos that *require* FPU?
