[hatari-devel] Small bug in Hatari Falcon emulation

["Roger Burrows" <anodyne@xxxxxxxxxxxx>]

When the "STe Bus Emulation" bit (0x20) in the Falcon Bus Control Register at 
$ff8007 is zero, "STe Bus Emulation" mode is set.  This affects bus error 
handling.  Hatari already models this as far as the I/O memory area is 
concerned (I haven't attempted to check how accurately yet).  But it also 
affects bus errors when accessing RAM, which Hatari does NOT model.  Basically, 
on a real Falcon with "STe Bus Emulation" enabled, there are NO bus errors 
generated for the whole $0 to $dfffff region, even in user state.  Even if RAM 
isn't present at an address, no bus error occurs.

This should be easy for any of the developers to verify, but I can post a copy 
of the test program I used if you would like.
