This guide will walk you through everything you need to know to get the multiplayer mod up and running, so you and your buddy can jump into the action together. Let's dive in!
What You'll Need
Before we get started, let's make sure you have all the necessary tools and files. This process might seem a bit technical, but don't worry, I'll break it down into easy-to-follow steps.
- A Nintendo Switch: Obviously, you'll need a Nintendo Switch to play Super Mario Odyssey. This mod requires a Switch capable of running custom firmware.
 - A Computer: You'll need a computer to download and transfer files to your Nintendo Switch. A Windows, macOS, or Linux machine will work just fine.
 - An SD Card: You'll need an SD card with enough storage to hold the necessary files and the game itself. A 64GB or larger SD card is recommended.
 - Custom Firmware (CFW): Your Nintendo Switch needs to be running custom firmware. This allows you to install and run homebrew software, including the multiplayer mod. Atmosphere is a popular choice.
 - Super Mario Odyssey Game Files: You'll need a copy of Super Mario Odyssey on your Switch. This can be a physical copy or a digital copy.
 - The Multiplayer Mod Files: You'll need to download the Super Mario Odyssey multiplayer mod files from a reliable source. I'll provide some links later in the guide.
 
Setting Up Your Nintendo Switch
Alright, let's get your Nintendo Switch ready for the multiplayer mod. This involves setting up custom firmware, which can be a bit tricky, so pay close attention.
Installing Custom Firmware (CFW)
Installing custom firmware can be risky, and if not done correctly, it could potentially brick your Nintendo Switch. Proceed with caution and follow instructions carefully.
- 
Prepare Your SD Card:
- Format your SD card to FAT32 or exFAT. FAT32 is generally recommended for compatibility.
 - Download the latest version of Atmosphere from GitHub. Extract the contents of the ZIP file to the root of your SD card.
 - Download the Hekate bootloader and extract the 
bootloaderfolder to the root of your SD card. - Create a folder named 
switchon your SD card if it doesn't already exist. 
 - 
Prepare Your Switch:
- Power off your Nintendo Switch completely.
 - Insert your prepared SD card into the Switch.
 - Enter RCM (Recovery Mode). The method for entering RCM depends on your Switch model. Google "how to enter RCM on Nintendo Switch [your model]" for specific instructions. Typically, this involves using a jig to short-circuit certain pins on the right Joy-Con rail while pressing the power and volume up buttons.
 
 - 
Boot into CFW:
- Use a USB cable to connect your Switch to your computer.
 - Use a payload injector (like TegraRcmGUI on Windows or NXBoot on macOS) to send the Hekate payload (
hekate_ctcaer_[version].bin) to your Switch. - Hekate will boot, allowing you to select "Launch" and then "Atmosphere" to boot into custom firmware.
 
 - 
Verify CFW Installation:
- Once your Switch boots up, go to System Settings. Under System, check the version number. If you see an "AMS" or "EmuMMC" suffix, it means you're running custom firmware.
