hi

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 ;(
