I'm quite sure NVDI does not use the PMMU. It's not the kind of
application that would typically make use of it, and definitely does not
require one.
 From Christian's analysis there appears to be some side effect related to
using or not using the PMMU, prefetch and cycle exact options, and
handling of exception vectors.


it might not use it, but if there's a buggy combination of mmu/prefetch/cycle exact in the 68030 cpu emulation and nvdi allows to show it, then it's better to use nvdi to debug this issue than just looking at the C code in newcpu.c, because cpu emulation with 68030/caches/mmu is *really* complex and not having traces of the crashing program makes it nearly impossible to guess ;(
