A minigame based on Sasuke vs. Commander, an early SNK arcade game, is hidden inside the Japanese version. To access it, do the following:
1. At the player selection screen, hold A + B and press Start to trigger the Level and Difficulty Select cheat.
2. Set to stage 5.
3. Now, hold Up + A + B on controllers 1 and 2, and then press Start on controller 1.

The ROM also includes the necessary font and space in the side bar for a score, an alternate screen layout, and multiple frames of animation for Sasuke and the ninjas, but none of it was used. It's likely that the developers had planned a more full-fledged port, but simply ran out of time.
