A hopping jiangshi pushes big mahjong tiles through 150 mazes, and every tile pushed against its twin vanishes — Sokoban crossed with mahjong solitaire on the Famicom, and seven 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, a triangle and the noise channel, 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.
