The Famicom couldn't handle these synths, but I tried to keep them close to the 8-bit. You can get the more orchestrated version from the recent Smash Bros.This one, I kept it simple, only adjusting the cymbals and adding a simple bass drum, as the original MIDI file didn't have it. That's understandable, if taken directly from the Famicom, as many games did not incorporate the 8-bit trap set, even though it's pretty decent for its day. The original Battletoads is an example of that. But I think it's part of the rom chip set in the cartridge, and not native to the Famicom/NES.
