How to set up emuNAND with Atmosphere on Mariko

What you'll need:

SX Gear	Hekate	Atmosphere & fusee	SigPatches
Download	Download	Download	Download

Setup:

Before you begin:

Non-OLED devices require a 64gb SD card or bigger!
OLED devices require a 128gb SD card or bigger!
You will need to disable automated backing up of your save data.
- To do this, go to ⚙️Settings 🠆 Data Management 🠆 Save Data Cloud 🠆 Settings and disable Automatically Back Up Save Data and Automatically Download Save Data.
Make sure you back up all of your files on your SD card to your PC and then delete them off your SD card!
- This is very important, because your SD card needs to be empty!
Once you have completed setting up your device, ensure that you never format your SD card to exFAT.
- exFAT users are more likely to experience SD card corruption than FAT32 users.
Make sure to read this so that you may later decide on which EmuNAND type to pick.

Step 1.

Extract these files into the root of your SD card:

SX_Gear_v1.1.zip - (Skip this if you use a HWFLY modchip)
hekate_ctcaer_x.x.x_Nyx_x.x.x.zip
atmosphere-x.x.x-master.zip
SigPatches.zip

Step 2.

Rename hekate_ctcaer_x.x.x.bin to payload.bin.

Place the file named fusee.bin in your /bootloader/payloads/ folder.

Create a file named hekate_ipl.ini inside of your /bootloader/ folder and paste this within the file:

⎗
✓
[config]
autoboot=0
autoboot_list=0
bootwait=3
backlight=100
autohosoff=0
autonogc=1
updater2p=0
bootprotect=0

[Atmosphere CFW]
payload=bootloader/payloads/fusee.bin
icon=bootloader/res/icon_payload.bmp

[Warmboot Error Fix]
fss0=atmosphere/package3
stock=1
emummc_force_disable=1
icon=bootloader/res/icon_switch.bmp

Create the file exosphere.ini in the root of your SD card and paste this inside
(this step is needed in order to blank your prodinfo so that you can avoid having your switch be banned):

⎗
✓
[exosphere]
debugmode=1
debugmode_user=0
disable_user_exception_handlers=0
enable_user_pmu_access=0
blank_prodinfo_sysmmc=0
blank_prodinfo_emummc=1
allow_writing_to_cal_sysmmc=0
log_port=0
log_baud_rate=115200
log_inverted=0

Afterwards create a file named default.txt in /atmosphere/hosts/ (the hosts folder won't exist, so make sure to create it)
and paste this in your default.txt file (this step is prevents you from connecting to Nintendo's servers):

⎗

# Block Nintendo Servers
127.0.0.1 *nintendo.*
127.0.0.1 *nintendo-europe.com
127.0.0.1 *nintendoswitch.*
95.216.149.205 *conntest.nintendowifi.net
95.216.149.205 *ctest.cdn.nintendo.net

Step 3.

Place your SD card back into your switch and turn it on. You'll launch into Hekate.
Select the Tools tab, then select Partition SD Card, and finally press Ok.

Now, pick what EmuNAND type you want to use:

To create a partition-based Emunand:

Non-OLED:
- Move the emuMMC (RAW) slider until it says 29 full, then press Next Step and finally press Start.
OLED:
- Move the emuMMC (RAW) slider until it says 58 full, then press Next Step and finally press Start.
To create a file-based EmuNAND:
- Press Next Step, and then press Start.

Once the operation is done, press Close and then select the Home tab.

Select emuMMC in the main menu, then select Create emuMMC

For partition-based EmuNAND, select SD Partition and then select Part 1.
For file-based EmuNAND, select SD File.

Wait for your emuNAND to get created. Once its done, select Close.

Turn your device off by pressing Power off.
Place your SD card back into your PC and move back any previously deleted files into your SD card.

Press the power button, and you'll boot into Hekate.
Click on Launch, and select Atmosphere CFW to launch into Atmosphere.
If you ever need to go into SysNAND without your CFW, then select Reboot and then select OFW.
