Abstract:The Nintendo Wii revolutionized the video game industry with its motion-controlled gameplay and accessible library. As physical optical media degrades over time, digital preservation has become a critical endeavor for historians, enthusiasts, and developers. Central to the preservation of Wii software is the Wii Backup File System (WBFS) format. This paper explores the technical origin of WBFS, its operational advantages over traditional raw disc images (ISOs), and its lasting impact on the emulation and homebrew communities.
