Revisional Differences

Two revisions of this game are known to exist, though the only notable differences are in the title screen:

Earlier	Later

• The earlier revision boots to a black screen, in which the background music starts to play. Afterwards, Level 01, which has the game's title, is loaded; the gameplay itself also starts in this level. The later revision, however, only displays Level 01 for a brief moment; the gameplay itself begins at Level 02. MBiTM is also not credited in the earlier revision.
