How to setup HATS from scratch
Step 1: Prepare the microSD Card
- Connect your microSD card to your computer.
- Format the card to FAT32 (use a tool like GUIFormat if the card is larger than 32GB).
- Go to the HATS GitHub and download the latest release.
- Copy all contents of the HATS zip file directly to the root of your SD card.
Step 2: Boot into Hekate
- Insert the SD card into your Switch and power it on.
- The PicoFly chip will pulse, and you’ll boot straight into the Hekate menu.
- Set up the date and time.
Step 3: Create the 12 GB Partition
We’re going to set aside that specific 12 GB chunk for your emuMMC.
- In Hekate, go to Tools (top tab) > Partition SD Card.
- Look for the slider labeled emuMMC (RAW GPP).
- Slide it until it indicates 12 GB.
- Tap Next Step and then Start.
- Wait for Hekate to finish “moving" your existing files and creating the partition. Once it’s done, your HATS files will still be right where you left them.
Step 4: Flash the emuMMC
Now we tell the Switch to actually use that 12 GB “room" we just built.
- Return to the Hekate Home tab.
- Tap emuMMC > Create emuMMC.
- Select SD Partition.
- Select Part 1.
- Hekate will now clone your internal system files into that 12 GB partition. This usually takes about 10–15 minutes.
Step 5: Launching HATS
- Go back to the Home tab.
- Tap Launch.
- Select CFW EmuMMC.
- The Switch will boot, showing the HATS splash screen and then the home menu.
