Thanks, I just saw the email.

Ok, that explains everything!

BTW, there's also a discrepancy with the 'college' module for the smondial2:
when it was first posted (I think it was Luis in the MECA forum), it had a size of 32kB, but the xml-file didn't work. When I've looked into the ROM I saw, that it's actually a 16kB ROM and the 2nd half was filled with 0x00 bytes, so I've truncated the file (to 16kB) and changed the xml-file, and it's working in CB-Emu since then.
But in MAME the file smondial2.xml still defines this college module as 32kB with an additional line: rom size="0x4000" offset="0" loadflag="continue".
What's now correct? Should I change my version, or should this be changed in MAME?
