Why when I download a ROM for MAME and run it it tells me that ROM or BIOS files are missing? I'm testing the new version of MAME.Could it be a problem

I don't know how this emulator works and it makes little sense to me, but I put all the files I needed in the right folders, read the FAQs, (they didn't help)
