According to a 1995 interview on a Geocities archive, the original diskettes used a custom copy protection that required a "checked update" to bypass. To this day, no working ROM has surfaced, but fans continue to search for the mythical OIRAN1983.UPD file. Another compelling theory involves Pioneer’s LD-700 laserdisc player.

Is it a forgotten film, a video game prototype, or a software update for a long-defunct system? According to a 1995 interview on a Geocities
