This paper explores the technical architecture and cultural impact of the XCI file format, specifically regarding Super Smash Bros. Ultimate on the Nintendo Switch. As the highest-selling fighting game in history, Smash Ultimate represents a unique case study in digital rights management (DRM) circumvention. By examining the structure of the XCI container (a cartidge dump) versus the NSP format (an eShop title), this paper analyzes how hardware vulnerabilities—specifically the Tegra X2 exploit—facilitated the proliferation of "Day 0" piracy. Furthermore, it discusses the impact of "Smash stacking" on SD card storage, the complexities of update integration, and the ongoing cat-and-mouse game between console modding communities and Nintendo’s litigious response.
