With the rise of Apollo 68080 core and the FPU needing more testing, some software needed a recompile to work on current Vampire cores.

Here is a sum up list of them :
* GuiGFX.library : http://aminet.net/package/dev/misc/guigfxlib_nofpu
* Ixemul.library : http://aminet.net/package/dev/lib/ixemul-48.3-bin-m68k (use ixemul-48.3-3-bin-m68k/sys/libs/ixemul-020s.library)
* Render.library : http://aminet.net/package/dev/misc/renderlib301
* SysInfo 4.0 : http://aminet.net/package/util/moni/SysInfo40_noFPU
* MadPlay : http://aminet.net/package/mus/play/madplay / http://aminet.net/package/util/libs/mpega_libmad
* ScummVM 1.8.1 : http://aminet.net/package/game/misc/scummvm-1.8.1-rtg

So when there is multiple CPU choices, which version should we pick? 020, 040, 060?

I was under impression that Apollo Core behaves mostly like 68040 so 040 would be my pick but opening posts says at least for ixemul that 020 is the correct one...

020 is fully compatible i wouldn't worry and yes that is the correct one.

Wait, should mpega_libmad from Aminet be non-FPU? It always crashes with 8000 000B for me.

I am asking because I recompiled a new version with -msoft-float and libm instead of libm040 and then it works. Is it due to FPU or something is libm040 incompatible with current core or something?

If libraries for 030,040 or 060 are for EC CPUs )no MMU, no FPU) we would ideally
use those for 68EC060, but that doesnt exist (not the CPU, Amiga libs and executables optimized)

So best are 68EC040, or 040 no FPU no MMU code.

020 is safe just because it is faster in code then 00, and yet didnt officially came with FPU (was addon) and MMU newer existed.
