CEMU is a closed-source Wii U emulator for Windows that allows users to play the console's titles on a desktop PC.

Setting up CEMU

Requirements

• Windows 7 64-bit or above
• Minimum 4GB of RAM
• Microsoft Visual C++ 2017 x64

Steps

Download

1. Download the latest version of CEMU here. Also optionally grab CEMUHook from here as well for some extra optimizations and features.
2. Extract the CEMU archive to a folder such as your desktop, and if downloaded, move the CEMUHook archive inside the CEMU folder that was just created, and extract the contents into the root of the CEMU folder. You may now delete the CEMUHook archive.

Setup

1. Run the Cemu.exe file and a Getting started window should pop up.
2. Optionally set your mlc01 path and your game path to a location of your choice (be warned this folder can grow to several GBs in size), and click Download community graphic packs.
3. In the next window, make sure to enable Automatically check for updates to keep your CEMU always updated. Click Close.
4. If you installed CEMUHook and it loaded successfully, a button that says Download now should appear at the bottom of the window along with text that says You are missing 4 out of 4 shared fonts. Make sure to click the Download now button to get the fonts. (Those who did not install CEMUHook don't need to worry about this, as NSMBU does not use any of the shared fonts)
5. Go to Options > Input Settings and configure your input device(s) and keybinds.

Game Installation

• MLC Method - The simpler method recommended to the average user

1. At the top bar, click File > Install game title, update or DLC, navigate to your New Super Mario Bros. U dump folder, and select the ./meta/meta.xml file.
2. If you have update or DLC folders, repeat the step above for each of them.

• Game Paths Method - A slightly more advanced method which may interest users with disk space constraints or using custom code, this method is REQUIRED for the latter.

1. At the top bar, click Options > General settings, then on the Game Paths section at the bottom, click Add, then navigate to and select the folder containing your New Super Mario Bros. U dump folder.
2. If you have an update folder, manually merge it on top of the base game folder through File Explorer, selecting "Replace files on destination" when prompted. This will make CEMU display the game in red on the game list, simply ignore it.
3. If you have a DLC folder, install it using the MLC Method.

Optimization

1. Go to Options > General settings and navigate to the Graphics tab. Inside this tab, change the Graphics API to Vulkan (experimental). If you have any issues with Vulkan, you can change to OpenGL. Set the Graphics Device to your fastest GPU that you have installed on your computer. If you get screen tearing, change the VSync option to Double buffering. Set Upscale filter and Downscale filter both to Bilinear, and set Fullscreen scaling to Keep aspect ratio.
2. Switch to the Audio tab. Here, change the API to XAudio2. If the audio is choppy, increase the latency to 60ms. Under Gamepad, change Device to Primary Sound Driver, and increase the volume to 50%. You may now close this window.
3. Click on the Debug tab and under Experimental, enable Async compile (Vulkan). Change the MM Timer Accuracy to 1ms. Finally, make sure to enable Use Cemuhook H264.

Crash Fixes

• Game crashes when pressing 2 / A on the titlescreen: (Caused by: Missing Mii files)
  • Fix Method 1. This method simply uses a graphic pack as a workaround. First make sure you have the latest updated graphic packs by going to the graphic packs menu and select Download latest community graphic packs. Then find New Super Mario Bros. U, and under Workarounds, select Crash Fix. (WARNING: This crash fix method is NOT compatible with any form of custom code, if you are using code hacks and are affected by this crash, you MUST use the alternative method below)
  • Fix Method 2. As an alternative, more permanent method, simply download these files and place them at cemu/mlc01/sys/title/0005001b/10056000/content/. NOTE: On newer versions of cemu some of those folders may need to be created.

Graphic Packs

1. To enable graphic packs, right-click on New Super Mario Bros. U in the game list, and go to Edit graphic packs.
2. If your PC is capable enough, you may want to improve the graphics of the game. If this is the case, enable Fancy FX, and optionally Resolution. You can increase the resolution to a size of your choice, but be aware that resolutions above 2560x1440 heavily decrease performance.
