Super Mario Bros vs Mario 3: Koji Kondo’s Underground Theme

Comparing the Super Mario Bros. and Super Mario Bros. 3 versions of Koji Kondo’s “Underground Theme,” focusing on how each uses the NES/Famicom soundchip.


Both themes use the NES’s five‑channel audio architecture, but the Super Mario Bros. 3 version introduces several major changes. Most obviously, SMB3 adds a new drum groove using lo‑fi DPCM samples and noise‑channel hi‑hats, but, also significantly, we look at how the two games use the pulse channels differently, shaping the timbre and overall character of each version of the theme.

These choices highlight not only Koji Kondo’s evolving creativity, but also composers were able to leverage the NES soundchip differently over the life of the system.

Whether you’re interested in game music, NES chiptune sound design, or how classic game composers created so much with so little, I hope this provides some background into how the “Underground Theme” remains one of the most iconic tracks in video game history.

Japanese Famicom Controller 2 Microphone

Retro console teardown meets audio hacking: turning classic hardware into sonic experiments.

Have you ever wondered what’s inside a Japanese Famicom? Well I did. Particularly what that microphone in controller 2 is like. Luckily, last summer when I was in Japan, I found a “junk” Famicom console for under $6 and, in this video, I break it down to check out what’s going on inside. I open up the controllers and the main system, extract the microphone, and wire it into a custom circuit to hear what it sounds like.

This is part teardown, part audio experiment, and completely perfect for fans of retro tech, DIY audio, and creative sound design.
