Thing is, the current cropping isn't enough for systems like the NES, Neo Geo and specific arcades, anyway. It's probably the only aspect in MAME that currently doesn't seem to be aiming for accuracy.

As I pointed out in MAMEtesters, it would be possible to avoid people complaining about having extra borders (or even noticing that anything has changed) by adding a "crop overscan" option that's turned on by default, something like this (along with a "screen x/y offset" option):

They may even think that something has been done to "fix the NES", as seen in the mockup.
