I like it that all the mame roms have specific filenames. I just wish the console roms were the same way. Yes, I know they have tools for that now, but all those tools did was proliferate the stupid 17 alternate bad dumps of each cartridge even more. I remember browsing one website a long time ago that actually had each alternate (bad) version of each rom.
It would be MUCH better on the console end, if the tools just identified one dump as correct, and labeled all others simply as corrupted, maybe that would finally get rid of all the clones.
