How to install Undertale Yellow on a Chromebook

Installing Undertale Yellow on a Chromebook

Undertale Yellow, a fan-made prequel to the popular indie game Undertale, has captured the hearts of many gamers. Today, we'll guide you through the process of installing this game on your Chromebook. This tutorial is specifically designed for Chromebooks with Intel or AMD processors that support Linux Apps. Unfortunately, this method won't work on Chromebooks with ARM64 architecture.


Before we begin, ensure that your Chromebook has Linux Apps support enabled. If you haven't done this yet, go to your system settings, click on the advanced section in the left panel, then click on the developers section, and turn on Linux apps.

Installation Process

Follow these steps carefully to install Undertale Yellow:

  1. Open your Linux terminal
  2. Add 32-bit architecture support:
    sudo dpkg --add-architecture i386
  3. Download and add the WineHQ GPG key:
    wget -nc && sudo apt-key add winehq.key
  4. Add the WineHQ repository:
    echo "deb bookworm main" | sudo tee /etc/apt/sources.list.d/wine_chrome_os_made_simple.list
  5. Update your package list:
    sudo apt update
  6. Install Wine and Winbind:
    sudo apt install --install-recommends winehq-stable winbind
  7. Configure Wine:
  8. Unzip the Undertale Yellow file:
  9. Navigate to the game directory and run it:
    cd Undertale\ Yellow\ v1_1 && wine Undertale\ Yellow.exe

Understanding the Process

Let's break down what these commands are doing:

  • We first add 32-bit architecture support because many Windows applications, including some games, are 32-bit.
  • We then add the WineHQ repository. Wine is a compatibility layer that allows us to run Windows applications on Linux-based systems like your Chromebook's Linux environment.
  • After updating the package list, we install Wine along with Winbind, which helps Wine interact with Windows networks.
  • The 'winecfg' command opens Wine's configuration panel. You can adjust settings here if needed, but the defaults usually work fine.
  • Finally, we unzip the game files and use Wine to run the game's executable file.


If you encounter any issues during installation or gameplay:

  • Ensure your Chromebook meets the minimum system requirements for the game.
  • Try updating your Linux environment and Wine to the latest versions.
  • Some games may require additional Windows libraries. You can install these using Wine's built-in installer (winetricks).


You should now have Undertale Yellow up and running on your Chromebook! This process demonstrates the flexibility of modern Chromebooks, allowing you to enjoy Windows games through the Linux environment. Remember, while this method works for many games, performance may vary depending on your Chromebook's specifications.
