      Dumping Games for pkNX ROM Editing/Randomization

      In this guide I'll be going over the (very) simple process of dumping your Nintendo Switch Pokémon titles for use with pkNX. This will work with the following games: • Pokémon: Let's Go, Pikachu! / Pokémon: Let's Go, Eevee! • Pokémon Sword / Pokémon Shield** For Sword and Shield, pkNX operates under the assumption that your dumped ROM includes the Ver. 1.3.0 patch. What you'll need: • A Nintendo Switch running Custom Firmware (preferably Atmosphère) • The latest release of NXDumpTool • The latest build of pkNX (steps on how to get the latest build can be found on its forum post) • Your console keys/title keys (you can obtain these files using Lockpick_RCM; send the RCM payload to your console, dump keys from your specified NAND, and boot into CFW) • A microSD Card with enough free space to dump your game (~5GB for LGPE, ~13GB for SWSH) • Means of transferring files between your microSD Card and computer • A computer running any recent Windows OS (x64) in order to run pkNX Steps: 1. Get into The Homebrew Menu as per your Custom Firmware 2. Run NXDumpTool 3. Select Dump gamecard content if you have a physical copy of the game, and make sure your Game Card is inserted 4. Select Dump installed SD card / eMMC content if you have a digital copy of the game, and navigate to your game of choice 5. Select RomFS options 6. Navigate to Use update/DLC and press Right on your D-Pad to change it from No to the latest patch     The latest patch will read as follows, depending on your game:    (Ver. 1.0.2) Pokémon: Let's Go, Pikachu! - 010003F003A34000 v131072 (0.0.2.0) (UPD)    (Ver. 1.0.2) Pokémon: Let's Go, Eevee! - 0100187003A36000 v131072 (0.0.2.0) (UPD)    (Ver. 1.3.0) Pokémon Sword - 0100ABF008968000 v327680 (0.0.5.0) (UPD)    (Ver. 1.3.0) Pokémon Shield - 01008DB008C2C000 v327680 (0.0.5.0) (UPD)    (Ver. 1.3.1) Pokémon Sword - 0100ABF008968000 v393216 (0.0.6.0) (UPD)    (Ver. 1.3.1) Pokémon Shield - 01008DB008C2C000 v393216 (0.0.6.0) (UPD) 7. Navigate back to the top of the list and select RomFS section data dump     This process will take some time; be patient, let it properly dump all of the contents and don't power off your console! 8. Once the dumping process has completed, exit out of NXDumpTool and access your SD Card (either via ftpd, nxmtp, or by ejecting the SD Card from your console and putting it in your computer) 9. Your dumps will be located in the following path on your SD Card: sd:/switch/nxdumptool/ 10. Inside the RomFS folder, you should be greeted to your ROM dump 11. The folder inside RomFS will be named after your ROM dump (e.g. Pok__mon Sword v393216 (0100ABF008968000) (UPD)); move this folder to your computer 12. Run pkNX and load the folder you just moved to your computer 13. Edit/randomize away! Once your changes have been made, a patch folder for use with LayeredFS will be generated in your ROM dump folder. Move this folder to sd:/atmosphere/contents/ (or whichever other location if you choose to not use Atmosphère) in order for your changes to be reflected in-game.
