Hekate is a powerful and user-friendly bootloader for the Nintendo Switch that allows users to customize and control their device's boot process.

One of the key benefits of Hekate is its graphical user interface (GUI), which makes it easy for even novice users to navigate and understand. The interface provides a variety of customization options, including the ability to change the device's boot logo and select the default boot configuration.

Another notable feature of Hekate is its support for emuMMC (Emulated NAND). It allows you to allocate a section of your SD card as internal storage (NAND) for your Switch while it's running custom firmware. This means you can keep your stock OS for online use in games you own; It also protects the system from potential bricks since all the software is run from the SD card and any modifications can be reversed or recovered from.

Features

• Fully Configurable and Graphical with Touchscreen and Joycon input support.
• Launcher Style, Background and Color Themes.
• HOS (Switch OS) Bootloader - For CFW Sys/Emu, OFW Sys and Stock Sys.
• Android & Linux Bootloader.
• Payload Launcher.
• eMMC/emuMMC Backup/Restore Tools.
• SD Card Partition Manager - Prepares and formats SD Card for any combo of HOS (Sys/emuMMC), Android and Linux.
• emuMMC Creation & Manager - Can also migrate and fix existing emuMMC.
• Switch Android & Linux flasher.
• USB Mass Storage (UMS) for SD/eMMC/emuMMC - Converts Switch into a SD Card Reader.
• USB Gamepad - Converts Switch with Joycon into a USB HID Gamepad.
• Hardware and Peripherals info (SoC, Fuses, RAM, Display, Touch, eMMC, SD, Battery, PSU, Charger).
• Many other tools like Archive Bit Fixer, Touch Calibration, SD/eMMC Benchmark, AutoRCM enabler and more.

Note: For maximum performance of UMS in Windows, you need to run nyx_usb_max_rate__run_only_once_per_windows_pc.reg, only once per PC you have. It only affects hekate's usb device. You can also view that file with text editor and see what it does. Linux/Mac OS users do not need that.

Installation

How to update:

• Drag n drop bootloader folder into sd card root and hit merge/replace.
• No need to delete that folder first, especially if you want your configs and payloads.
• You can choose to update your RCM injection device or PC with the new hekate_ctcaer_x.x.x.bin or not.
• In any case, bootloader/update.bin, will be checked and if newer it will get loaded.
• update.bin is hekate and it is already copied with the bootloader folder drag n drop update process.

Notice about Atmosphere 1.0.0 and up:

• The fss0=atmosphere/fusee-secondary.bin in hekate_ipl.ini must be changed to fss0=atmosphere/package3.
• And make sure that atmosphere/contents folder does not have old Atmosphere components.

Notice about resized emuMMC:

• Resized emuMMC does not have the slow bug anymore.
• You can create a new one or recreate it via Nyx and the issue will be gone.

  • It also significantly affects high density ram modules like in 8GB configurations.
  • Additionally, they can be improved extra with the ram_oc_opt ac mode also..
  • Fixed an issue where sometimes timing reduction was not allowed on 1600 MHz.
  • A new ram_oc_opt= parameter was added to support advanced ram oc configuration for both T210 and T210B01..
  • Mostly for users with T210/LPDDR4 because of low frequencies and others that like to optimize (T210B01/LPDDR4X)..
  • Read more in wiki.
  • ram_oc_vdd2 max voltage limit was raised to 1237mV for T210. T210B01 remains at Jedec max of 1175mV.
