Hey, could someone help me with this?

I downloaded the no intro NES romset and want to delete all rom clones, but im not having any luck.
I got the standard and the parent-clone dats from dat-o-matic, however i cant for the life of me understand how clrmamepro works. I also tried romcenter 3.7, but it didnt recognize the roms (using the dat for romcenter), v4.0 beta 5 do but there is no 1g1r option.

Is there another way to do it, besides manually?
