We could only wish we were playing this right now... maybe...
This game was never completed and/or given a public release.
As a result of this, keep in mind that the developers might have used or deleted some of the content featured here, had the game actually reached store shelves.
Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: The (non?)existence of the Shun (Blink) modifier.

No, Jaleco, lawsuits are not to be lost.

Unused Graphics

Offset 0x1A80 of Bank 10 contains an early graphic, known to have been unused since the original Rock'n Tread.

Scattered through Banks 8 and 9 are the original icons for Oni Mode and for the non-existing Hard Mode, also from the original Rock'n Tread. Their palettes are no longer loaded, however.
