This section will take you through installing and configuring Cemu for the very first time. It is important you read all of the text here before proceeding to fully understand the instructions.

Introduction

Cemu can be installed by extracting a .zip file to somewhere on your PC. In this guide, we use the Desktop as this location.

Before we launch it, we tweak the program slightly to run better, including fixing some scaling issues and making sure it runs as administrator. This is to ensure it has access to all the files it needs.

When we finally open the application, it will take us through the quick-start guide. This helps to set up the emulator properly with the necessary files and folders.

mlc01 path

The mlc01 path stores what the Wii U would normally store on its internal memory. It’s essentially the emulated hard drive of the system. This means it stores all system files, system apps, installed updates, DLC, and created save data.

Setting this is optional. By default, the mlc01 path will be stored in the Cemu directory. We recommend not changing this unless you have limited space available on the current disk.

Games path

This is rather self explanatory, it’s a folder where you keep your games. Due to the way that Cemu now installs games, this is unnecessary.

Community Graphics Packs

There’s a button you can press called “Download community graphics packs”. This will download a set of graphics packs for a select number of games, these packs will allow you to alter a game visually or how it will run.

This includes letting games display at higher resolutions, run with higher framerates, adjusting bloom, improve anti-aliasing, use game mods, and an assortment of other features. We recommend that you download these to allow tweaking your games for better performance.

Preparations

  1. Extract the Cemu .zip file to your Desktop
  2. Open the Cemu folder
  3. Right click on the Cemu executable
  4. Click Properties
  5. Navigate to the Compatibility tab
  6. Enable the option “Disable fullscreen optimizations”
  7. Enable “Run this program as administrator”
  8. Click on Change high DPI settings
  9. Enable “Use this setting to fix scaling programs for this program instead of the one in settings”
  10. Enable “Override high DPI scaling behaviour. Scaling performed by: Application”
  11. Click Apply -> OK

    These options are set to help avoid issues on various Windows versions, file restrictions, or display resolutions. That said, one or more of these options will not be necessary for everyone, but not setting them may result in complications.

Configuration

  2. When prompted, grant administrator access

    You will now be greeted with the Cemu quickstart guide. This take you through setting up the emulator for first use.

  3. Leave the Custom mlc01 path field blank
    • If you wish to store your Cemu system on an external drive, please select it here instead of leaving it blank
  4. Leave the Game paths field blank
    • In newer Cemu versions, games are stored in the mlc01 path instead of here
  5. Click Download community graphics packs button to automatically download the latest packs
  6. Click Next

Finishing set-up


  1. For now, do not click Configure Input
    • We will do this next in more detail
  2. Enable “Automatically check for updates”
    • If you don’t wish to get update notifications, you may update Cemu manually with an option under the Help menu
  3. Click Close

Now we’ve gone through the quickstart guide, we’ll move onto properly mapping controller inputs, (including motion controls).
