Signature patches are created to be used alongside Atmosphere for loading certain homebrew from the home menu.

1. Download the latest release.

   • If you use fusee-primary.bin to boot into atmosphere, download fusee.zip.
   • If you use fusee-secondary.bin to boot into atmosphere, download hekate.zip.
   • If you're unsure on which release to get then check your hekate_ipl.ini file located in your /bootloader/ folder.
     • If you have no such file, then get the fusee.zip release.
     • If you see the following line payload=bootloader/payloads/fusee-primary.bin in your hekate_ipl.ini file, download fusee.zip.
     • If you see the following line fss0=atmosphere/fusee-secondary.bin in your hekate_ipl.ini file, download hekate.zip.

2. Unzip the release you've chosen into the root of your SD card.

   • Make sure to click yes for overwriting any files and merging folders.
   • Make sure the /atmosphere/ folder in the zip merges with the atmosphere folder on your SD card! You should not have an /atmosphere/atmosphere/ folder, nor should you have an /sd/, /fusee/, or /hekate/ folder on your SD card.

3. Boot into atmosphere. You should now be using signature patches.

If you wish to start your CFW with Hekate, we highly suggest chainloading fusee-primary. This is the best method to boot Atmosphere without directly pushing fusee-primary.bin.

To chainload atmosphere place the latest fusee-primary.bin in /bootloader/payloads/ then edit your hekate_ipl.ini to contain the following,

[Atmosphere CFW]
payload=bootloader/payloads/fusee-primary.bin

I do not boot this way, and I suggest you don't either. The important thing to know about this method is that you need to grab the special hekate.zip and then edit your hekate_ipl.ini to contain kip1patch=nosigchk. Like this:

[CFW - FSS0 SYS]
fss0=atmosphere/fusee-secondary.bin
kip1patch=nosigchk
emummc_force_disable=1

[CFW - FSS0 EMU]
fss0=atmosphere/fusee-secondary.bin
kip1patch=nosigchk
emummcforce=1
