Meh...it's probably fine.
Many early 2000 games I'm fond of used SecuROM. That's always a fun one.
To the typical consumer, the action of inserting the DVD should communicate to the computer their intended action.
Every additional step, especially if it requires reading, pushes them further to just using a dedicated device for CD/DVD consumption.
To someone like you and me that might seem like an ideal practice, but to the typical consumer it's a usability problem.
NES emulators have been ported to basically everything, which in turn makes NES games playable anywhere. And this includes modern NES games as well, as long as they were tested against either super-accurate emulators or real hardware (to ensure no reliance on specific emulator quirks).
