Yep, agreed.

Too many false bug reports came from MAMEUI which didn't enforce this behavior (and worse, didn't even bother to tell you) Maybe it does now, maybe it's still stupid.

Of course this is one of the reasons MAMEUI was popular. I tried convincing somebody to switch to commandline / regular and they didn't want to because it told them that their roms had bad checksums. Their roms always had bad checksums, they were running bad dumps, they preferred to not know. (Game in question was Marvel Vs Capcom, there was a bad rom in the parent set that was redumped at one point, it would even cause the game to crash in places)
