I've completed also the FPSP040. Since there are no separate test cases for it, i've used the ones for the 060 (with a few fixes, since the 060 masks the FPCR when read with $FFF0, but the 040 doesn't).

 

The remaining failures seem all to be related to the FPIAR. See attached file. Could there be a problem in Hatari with that?
