The ending hasn’t been implemented yet, but graphics and code still exist for an alternate ending.

The bosses are unfinished, usually ending the stage prematurely.Most of the sound effects and music are missing.The drum snare samples are using the samples from Phantasy Star II US.This build has a level select and cheat mode enabled by default.As a result, this caused the wrong ROM to be included in the pack (and was possibly archived improperly by SEGA as a result). It looks as if the ROM wasn’t properly identified in the archive (given the file name SHINOBI1.BIN, while a later version more in line with the retail release was given the file name SHINOBI2.BIN).We also have the added advantage of having the correct build date of the ROM to properly identify just how early it is in comparison to what was released. This means that the ROM that was included in the Sega Smash Pack release actually originated from the Final ROM Archive. This ROM is almost identical to the ROM that was discovered a few years ago but without the SEGA Channel information in the header.
