So I verified my mach3.chd with chdman and it turned out to be successful/ok. I also had a problem with my Cube Quest chd and that too showed up ok with chdman. I will try the other stuff you said soon and let you know my findings. I created the dat file with 129.

Can I assume that the chds that I scanned (with chdman) are correct and that I'm probably doing something wrong with CLRmame?
