Fans of avant-garde Japanese cinema might recognize Takechi’s signature style: beautiful, static visuals contrasted with shocking, almost -like sequences.

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.

Original 35mm prints of 1980s films often suffer from color fading or graininess. A "checked" update usually signifies that the file has been verified for quality—specifically, that the colors have been corrected to reflect the original theatrical intent and that the resolution has been upscaled to 1080p or 4K.
