I agree that that's annoying as well... but coincidentally something similar can also happen to NES/SNES emulators if they use a "ROM database". They aren't quite versioned like on mame, but if you don't use their special checksummed ROMs they will run, but try telling you that you have a bad dump... only problem is that most NES ROMs have bad headers altogether. (I've seen a lot that say they have 8k of battery-backed SRAM when they infact don't. I wound up spending a week rewriting the headers on my ROMs from scratch, referencing the pcb pictures online. Edit: this also includes bad Disk Dude overdumps that still haven't been fixed ~40 years later...)
