I have it working in RA using MAME core and I know for that you do need to have matching files named what the software list is looking for but I don't know if there is some command that would change that I tried to get it running for Atari 5200 (and did) but my files weren't zipped (which is an easy fix) but they weren't named correctly either and I quickly grew bored of renaming the files. It would be cool if some one put out a software list rom sets using the proper naming for MAME I know I would download them all just in case MAME ever did become easy to emulate these systems. That or a program that would parse the files and rename them to the software list names would be cool.
