The Nsf and the MP3 are a bit different for these but this is a modified VRC7 cover of Bridge Zone off of the Sonic the Hedgehog for SMS/Game Gear.
Search Sound Cloud (Jredd) or Youtube (Jreddd) with 3 D's to hear the Mp3. I tried putting up a link but there is some strange thing I have to do to make it work on these forums which I have forgotten how to do.
