Shinobi (Sega Master System)

Shinobi
Developer: Sega Publisher: Sega Platform: Sega Master System Released in JP: June 19, 1988 Released in US: 1988 Released in EU: 1988 This game has unused music. This game has a hidden sound test. This game has a hidden level select.

The Master System Shinobi is a conversion of Sega's classic ninja-themed side-scrolling action game for their own 8-bit console. This version differs mechanically from the arcade original thanks to the inclusion of a life gauge, the ability to carry more than one Ninjutsu art, and various new powerups. All of these new features were later carried over to the game's own Genesis sequel The Revenge of Shinobi.

Unfortunately...the conversion team forgot to include the ending.

Stage Select

There are two ways to access the stage select, all on the title screen:

• Hold Down and press 1 or 2.
• Press Down, Down, Left, Right, Up, Up, and then 1 or 2.

After entering either code, select which stage to start at by pressing Up or Down and then 1 or 2 to confirm.

Unused Music

These unused music tracks were published in the 2009 album Legend of Joe Musashi: Shinobi Music Collection (catalog number WM-0626-9). Most of these are renditions of music from the arcade version, with only one exception. The Master System version's soundtrack (including these unused tracks) was composed in two versions: standard PSG renditions, and enhanced renditions that utilize the "FM Sound Unit" peripheral released only in Japan.

Track Title	PSG rendition	FM rendition	Notes
BGM 3			Background music played in the arcade version during various stages, most notably in Mission 2-1. The arcade version has different background music depending on the stage, but for some reason the Master System version uses the same BGM for every stage (except boss battles).
Stage Clear			The standard stage clear jingle used in the arcade version. The one that's used in the Master System version is only played in the arcade version after defeating a boss.
Main BGM 2			An alternate rendition of the main theme with a faster tempo.
Fanfare			The only track that isn't a carryover from the arcade version. Perhaps it was intended to be played after defeating the final boss, or for clearing a bonus stage?
