Hi

would  you be able to build a small test program that uses those FPU 
instructions where you see some differences (crash or other) between old 
cpu core and new cpu core ?

It would help to debug (instead of running the whole quake 2)

If possible, please specify what FPU/CPU options were ticked in Hatari's 
UI when you get different results.
