The demand for these updated dives is driven primarily by two forces: Physical cartridges degrade. Switch cartridges, coated in a bitter agent to deter swallowing, are also susceptible to bitrot over decades. An XCI dump stored on a redundant NAS (Network Attached Storage) server ensures that Odyssey ’s code exists indefinitely, immune to the eventual failure of the original silicon. Furthermore, the "high-quality" aspect appeals to the digital minimalist. A user running custom firmware (CFW) on their Switch or a PC emulator (like Yuzu or Ryujinx) does not want to carry 20 cartridges; they want a single SD card containing Odyssey alongside Breath of the Wild and Metroid Dread . The update files are crucial here, as they often include performance micro-patches that reduce stutter in heavily populated areas like New Donk City’s festival sequence.
