Years ago i kept only working roms too and i believe you can set up clrmame to handle that problem by setting it up to run full sets. If i remember correctly it will put all needed files in each rom zip file. I think right now its default is to just put the unique clone files into the clone zips but by changing settings you can have clrmame build complete rom files even for cloned. Of course Roman would know for sure or read the clrmame how to, but im sure its still true today as i used to do it.
