Setup and Overview

This section provides setup and installation instructions and an overview of the RNG tool.
Required Software
Tools and Applications
Installation Instructions
  1. Download .NET 9.0 and run the setup wizard until complete. This is a required program dependency.
  2. Download and extract owoow.zip into a fresh, empty folder.
  3. If you are using Wi-Fi instead of USB connectivity, extract ldn_mitm.zip into the new owoow folder.
  4. Move the atmosphere and switch folders to the root of your SD card. Agree to overwrite folders if prompted.
  5. Reboot the console into your chosen CFW environment (it is recommended to use SysCFW).

Ensure that sys-botbase (bundled with the owoow download) and ldn_mitm have been properly installed before continuing. You should see two separate folders named 430000000000B and 420000000010 inside the atmosphere/contents directory of your SD card if done correctly.

If ldn_mitm is not available or there is no working release, you will have to connect to Y-Comm or enable LAN mode for Wi-Fi connectivity. You can enable LAN mode by going to the settings in SWSH and pressing L + R + L-Stick (Booting LAN, LAN enabled). You will not have a 420000000010 folder in the atmosphere/contents directory since the outdated sys-module will crash Atmosphère.

Program Connectivity Instructions (WI-FI ONLY)
  1. Launch owoow.exe. Ensure that the program launches properly with no issues.
  2. Type the local IP address of the console into the Switch IP: field.
  3. Start the game. You can click the Connect button on owoow once you see the title screen.

If you experience connectivity issues using Wi-Fi, refer to the SysBot.NET Wiki (Wi-Fi Troubleshooting) page for tips and advice. Make sure to follow every step; this should resolve 99% of user issues.

Program Connectivity Instructions (USB ONLY)
  1. Launch owoow.exe. Ensure that the program launches properly with no issues.
  2. Close the program to produce a config.json file, then open this in a text editor like Notepad.
  3. Change the protocol to 1 for USB connectivity, save the changes, then close the file and launch owoow again.
  4. Open the config.cfg located in atmosphere/contents/43000000000B on your SD card in a text editor.
  5. Change the text to usb and save the changes. Reboot your Switch after doing so.
  6. Follow the instructions found on the SysBot.NET Wiki to learn how to configure a new USB connection on your Switch.
  7. Connect your Switch to your PC via a USB cable, launch owoow, and start the game. You can click the Connect button on owoow once you see the title screen.

If you experience connectivity issues using a USB connection, refer to the SysBot.NET Wiki (USB Troubleshooting) page for tips and advice. Make sure to follow every step; this should resolve 99% of user issues.

  • Cram-o-matic - Used for manipulating the Cram-o-matic.
  • Watt Trader - Used for manipulating the Watt Trader.
  • Digging Pa - Used for manipulating Digging Pa.
  • Wailord Respawn - Used for respawning the Isle of Armor Wailord.

Although Wailord Respawn is not directly related to item RNG manipulation, it will be included in this guide as the underlying concepts are similar.

The Basics

Learn about common and advanced techniques used to advance the RNG state and hit target frames.
Advancing the RNG State

Explore the various techniques used to advance the RNG state. Some actions advance the RNG state slowly, some will advance in a predictable manner, and others will cause the state to advance in a rapid and unpredictable manner.

Continue to advancing the RNG state

Using menu close prediction to advance the RNG state in a predictable manner. This essentially guarantees success in hitting the correct target frame. Menu close prediction is the preferred method and will be used extensively throughout the guide, so make sure you have a good understanding of how it works.
