 Hi Roger,

I just created a little test program that executes that PMOVE
instruction, and it seems to work: I see 11 bombs on the screen, i.e.
the line-f exception has been triggered. Could you maybe send me your
code so that I can check whether yours is behaving differently here?

Concerning the crash in the debugger, I think this has already been
fixed in the development version of Hatari. I encountered one of two of
those crashes some months ago, when I integrated the 68030 MMU code
into Hatari, and I fixed the debugger accordingly.
