Interesting. I grabbed an updated version of mess and saw that font data 
in there. It seems that later versions (after some point) of mess do not 
use the ROM data for the hardware font. I still have some odd behaviour 
with mess crashing depending on what the ROM is filled with but that is 
probably due to a bug in mess somewhere and possibly fixed in one of the 
later patches that I haven't applied, though why the fill value would 
affect anything is beyond me.
