Okay, I think I understand. I thought that newer rom sets had the original files PLUS new stuff. I didn't realize that files were being removed.

Any suggestions on how someone can go backwards like this since most files around are for the newest version.

Oh, and thanks Roman. I have found clrMAME so useful, and am constantly trying to improve my understanding of it.
