Research status
Structured source record
01

Release context

The documented release is December 15, 1985 for Japan on Sega Master System. Date precision is preserved exactly: the archive does not invent a day when the source records only a month or year.

02

Regional differences

This record is scoped to Japan. The linked structured source does not document a separate regional title or package difference, so PLAYBACK does not infer one.

03

Physical packaging

The physical format is documented as Cartridge / Sega Card. The current structured source does not enumerate every insert, manual, sleeve, or bonus item, so no unverified contents are claimed.

04

Editions and revisions

No separate limited, bundle, or collector's edition is currently documented beneath this game family.
