Popo and Nana hammer their way up 32 mountains to win back the vegetables a giant condor stole — a launch title of the NES, and five short tunes.

Nothing here was transcribed by ear: every note was read out of the cartridge and is played by an emulated NES sound chip — two pulse waves and a triangle, each on a keyboard of its own.

The music and the game belong to their composers and publishers; this site only shows how the cartridge plays it, for learning.
