It's great that the ROMs for the H8 are now available... 


I have recompiled the virtual_h8 project, and based on some warnings, it appears to have a few bugs in the processor emulation.  In the file processor.cpp, the following code is in four places:
S = (A & 0x0080 != 0);

And the compiler provides the following warning:
c:\H8\code\virtual_h8\processor.cpp(2452) : warning C4554: '&' : check operator precedence for possible error; use parentheses to clarify precedence

In looking at operator precedence, it does appear to be a problem since the precedence makes it equivelent to:
S = (A & (0x0080 != 0 ));

Which doesn't make any sense. It should be:
S = ((A & 0x0080) != 0 );

I've sent email to the author (David Wallace) so it can be addressed in the next release.
