What Does “Update Hot” Mean?

In the Switch scene, “Hot” typically refers to one of three things:

  1. The latest firmware compatibility patch – An update that makes the game run on newer Switch firmware (e.g., 18.0.0+).
  2. A performance improvement hack – Community patches that stabilize framerate in New Donk City or reduce loading screens.
  3. A leaked update before official announcement – Rare, but “hot” implies fresh, recently dumped, and verified.

For Super Mario Odyssey, the “hot” update right now is Version 1.3.0 (the final major patch that added Balloon World and Link’s costume from Breath of the Wild). The latest firmware compatibility patch – An update

Using XCI Files:

  1. Convert XCI to NSP: Tools like XCI to NSP Converter can be used, but be cautious and ensure the tool is up-to-date and trusted.
  2. Follow similar steps as NSP users, keeping in mind that XCI files might require additional steps or tools to work with modern firmware.

What is an NSP File?

NSP (Nintendo Submission Package) is the official digital format. When you buy Super Mario Odyssey from the Nintendo eShop, the file downloaded to your SD card is an NSP. In the homebrew scene, NSPs are preferred for:

  • Installing directly to a modded Switch (via Tinfoil or Awoo Installer).
  • Smaller file sizes (compared to XCI) because they are compressed.
  • DLC and Update integration – NSPs handle layered updates cleanly.

NSP and XCI Files

  • NSP Files: These are essentially digital packages used by Nintendo for distributing games through the eShop. If you're looking to install an NSP file, typically, you'd be looking into custom installations via tools like the Nintendo Switch Homebrew Menu. This process is more complex and involves risks, including the potential for bricking your device.

  • XCI Files: These are game files extracted from Switch cartridges. Like NSPs, handling XCI files involves complexities and potential legal issues, primarily because they are often used to distribute pirated copies of games.

Part 3: How to Apply the Super Mario Odyssey Update (Step-by-Step)

Whether you are using a modded Switch (Atmosphere/CFW) or a PC emulator (Ryujinx/Yuzu), the process differs. Below is the current “hot” method.

What is an XCI File?

XCI is a raw cartridge dump. It is a 1:1 copy of the game card data. Key advantages include:

  • Plug-and-play on emulators – No installation required.
  • Slightly faster load times on PC (due to linear data access).
  • Great for SX OS users (though SX OS is largely deprecated, legacy users still seek XCI).

4. Legal and Ethical Analysis

  • Copyright infringement: Reproduction and distribution without license.
  • Digital Millennium Copyright Act (DMCA), Section 1201 – anti‑circumvention.
  • Notable legal actions: Nintendo v. RomUniverse, Nintendo v. Tropic Haze (Yuzu).
  • Ethics: Impact on developers, difference between preservation and piracy.
  • Fair use arguments – interoperability, archiving, and their limits.
