hi

never tried myself, but it's possible there's an issue in the debugger. 
the reason is that the mmu on falcon/tt has often some translation 
tables in the lower part of ram ( < $800 ) and on Atari this requires 
the S bit to be set.

I fixed this in the emulation itself a long time ago, but maybe the 
debugger use some memory access functions that don't set S bit when 
doing 68030+mmu and displaying ram content.

Needs to be checked, I need some free time later for this :)
