TKMM on the Switch

       


Prerequisites

  1. Tears of the Kingdom base game and update (1.1.0 or later) either installed on your SD card or dumped with nxdumptool (as an XCI or NSP file).
  2. Lockpick_RCM (For dumping your keys)
  3. nxdumptool (Only required if your game/update is a cartridge, or installed to internal memory)
  4. HEKATE (Download the hekate_ctcaer_(version).zip release of hekate)

Preparation

1. SD Card Setup

To install TKMM-NX,

  • Download tkmm-nx.zip and extract it to the root of the SD card (or install it later from the Homebrew app).
  • Extract hekate_ctcaer_(version).zip and Lockpick_RCM_Hekate.zip to the root of the SD card (replace existing files if prompted).
  • If needed, install nxdumptool by copying nxdt_rw_poc.nro to the /switch folder in the root of the SD card. (See Ensure TotK is Accessible to determine if you need this.)

2. Ensure Tears of the Kingdom is Accessible

TKMM-NX needs access to the base game and update data (version 1.1.0 or later) in order to function, as well as the Switch's keys to decrypt them.

To determine where the base game and update data are installed, refer to Data Management > Manage Software > Tears of the Kingdom in the Switch's settings.

    Switch Data Management

If both Software and Update Data are listed under microSD Card, you do not need to dump your game, and all that is required is dumping the Switch's keys.

Otherwise, only parts not installed on the microSD Card need to be dumped. Refer to Dumping Tears of the Kingdom for more information.


3. Dumping Keys

To dump the Switch's keys, open the Payloads option in HEKATE and launch Lockpick_RCM.bin, then select Dump from SysNAND. (Use the power button to select and volume up/down to navigate.)


4. Dumping Tears of the Kingdom

Begin by running nxdumptool (nxdt_rw_poc) from the Homebrew Launcher.


Base Game

  • If the base game is a cartridge, insert the cartridge, then navigate to gamecard menu / dump gamecard image (xci) and select start xci dump.
  • If the base game is installed to system memory, open the user titles menu, select Tears of the Kingdom, navigate to nsp dump options > dump base application and finally select start nsp dump. (It is also possible to re-download the game from the e-shop, which will install it on the SD card and save space in the system memory. If this is done, be sure to run the game at least once, and dump the keys again.)

Update

  • If the base game is installed to system memory, open the user titles menu, select Tears of the Kingdom, navigate to nsp dump options > dump update and finally select start nsp dump. (It is also possible to re-download the game from the e-shop, which will install it on the SD card and save space in the system memory. If this is done, be sure to run the game at least once, and dump the keys again.)

Join the nxdumptool Discord server for assistance on how to dump if needed.

Tip

TKMM can handle split files; combining them after dumping is not required.


Installation

Installing from the Homebrew App Store

If TKMM-NX was not installed in the preparation section by extracting it to the SD card, it can be installed from the Homebrew App Store (under the advanced category).

    Homebrew App Store


Post-Installation Setup

If TKMM-NX is installed correctly, a boot entry for TKMM will appear under More Configs in HEKATE.

    Hekate

The first time TKMM-NX is opened, the setup wizard will appear. If the preparation section was done correctly, no additional setup will be required.

If the setup wizard cannot find the keys or the game/update, review the steps in the preparation section.

Integrated TotK Optimizer / Ultracam

MaxLastBreath, the developer of the TotK Optimizer (Ultracam), has allowed the TKMM Team to use his mod and directly integrate it into TKMM.

It can be enabled from the TotK Optimizer page on the left (star icon). Keep in mind, the Switch may not be able to boot the game if you select any resolution higher than 1080p and 60 FPS.

Note

You do not need to install Ultracam separately, as it is already integrated into the TotK Optimizer page. For users with access to the beta versions, install the TKCL file provided on the official NX Optimizer Discord Server. (See Using Mods for installing TKCL files.)

    TKMM TotK Optimizer Page

For more information, visit the official website of the optimizer and get a better idea of what this mod is and how best to configure it for your Switch.

All assistance requests related to the optimizer should be directed to the Discord server for the optimizer.

This guide is based on the original Game Banana tutorial by lordbubbles, consider supporting him on KoFi.
