Shinobi (NES)

Shinobi
Developers: Unknown (most likely Sanritsu Denki) Publisher: Tengen Platform: Unlicensed NES Released in US: 1989 This game has unused music. This game has a hidden level select.

The NES Shinobi is a port of Sega's arcade game and very similar to the Master System version in terms of play mechanics and graphic design (right down to the inclusion of a life gauge), but nowhere near as polished and very buggy. Still, it does have some semblance of an actual ending, which the Master System version lacked.

Unused Music

The soundtrack for the NES Shinobi has eleven tracks (all of them renditions of music from the arcade and Master System versions), but only four are actually played in-game: the standard stage music (BGM2), the bonus stage theme (BGM1), the stage clear theme, and the ending/game over theme. The unused tracks are as follows, with the titles taken from the Legend of Joe Musashi album:

Title	Track	Notes
BGM3		Played in Mission 2-1 in the arcade version. The NES version uses BGM2 (originally the Mission 1-2 theme) for every stage, including boss battles.
BGM4		Played in Mission 2-2 in the arcade version and in the bonus stages in the Master System version.
Boss 1		The standard boss theme of the arcade and Master System versions.
Boss 2		The boss theme for the Black Turtle helicopter battle in the arcade version.
Mission Clear		Played in the arcade version when the player defeats a boss, and in the Master System version as the standard stage clear theme.
Bonus Stage		The NES version uses BGM1 (originally the Mission 1-1 theme) for the bonus stages.
Miss		Played in the Master System version whenever the player dies (i.e., a "miss" in Japanese gaming terminology).
