I doubt a website emulator would support anything like that, but downloadable NES emulators certainly do. I won't link anything because I'm still not 100% certain on RAFO's copyright policies (I'll check with Ben) but google should be able to easily help you out.
Is there Super Mario Brothers for the computer?

Emulators are legal (at least in the US, so yeah, check with Ben); ROMs are not.

True, but the distinction is only a matter of semantics.

Some roms are considered abandonware. However I assume Mario Brothers is not. *NM*

Abandonware is not a legal term.
