It's only by luck, as the wrong CPU is running after the reboot.

As I explained before, changing of CPU in the GUI makes the code run 
into newcpu.c:check_prefs_changed_cpu (void)
and at the end of the function, it goes to

    if (changed)
        set_special (SPCFLAG_BRK);


But when the code returns to the running CPU (like m68k_run_1 (void), 
m68k_run_2 (void), ...) the value of SPCFLAG_BRK is back to 0 and the 
program doesn't return to m68k_go (that's where the change of CPU occurs).

I haven't managed to find this problem, and it's quite annoying. Some 
help would be appreciate on this one.

For me, only the 68000 prefetch, 68000 cycle exact and the 68040 +MMU 
are actually not working.
