Thanks! Indeed, I see the same here with that program.frank.lukas wrote: ↑Sun Jul 10, 2022 4:07 pm CPUFPU Program also doesn't show the FPU just like MiNT/XaAES do ...

I'll take a look what that program does for detection at some point
I'm guessing it's not reading the _FPU cookie and perhaps the emulation is not reacting properly to whatever it does to detect it (I wouldn't know.. I can't claim to understand what the emulation code is doing. I basically just ripped it out of the NetBSD kernel, got rid of NetBSD dependencies, and then made the necessary modifications and glue code so it could interface with our operating system instead)
Does it work with something known to work though?
The _FPU cookie should be $00040000 after running fpemu.prg
I tested Gembench, Nembench, Kronos, "FPUTEST.TOS", "FPUREC.TOS" here. And my own little test program of course that was built for 68020-60.
