Abstract
In game archive research, there are issues related to the preservation of game works, such as the fragility of data stored on media and the deterioration and obsolescence of hardware, etc. In recent years, attention has also been paid to the preservation of ”related materials,” which refers to things other than the games themselves. In this presentation, we will take the instruction manuals that come with video game software as part of this effort, expand on previous research in this area (Ohana & Uemura 2012, etc.), present their material value, and comprehensively examine the challenges and prospects for their archival use.
