Cemu Questions:
Where can I get games, updates, or DLC?
|
- You dump all of this from your own Wii U console. You may use a friend's console as long as you own the content you are dumping. No exceptions, do not ask for alternatives.
- Asking for links or other will result in a warning or ban in any Cemu Discussion areas. Cemu will never support illegally sharing copyrighted content.
- Dumping the content from the Wii U is covered by: [ Getting Started Guide ]
|
Cemu says it needs a System Update when trying to launch a game.
|
- This message means you have not applied the latest update to your game.
- Most games will not work unless they have been given update data to use.
- To dump your Update/DLC from your Wii U and install them on Cemu, you may follow: [ Getting Started Guide ]
- If the message still appears after installing the update for the game, you did not apply the update correctly or the update is corrupt and needs a fresh dump from your console, then reinstalled.
- Ensure your Update data has a complete Meta folder before installing it again.
|
How do I get games to show up in Cemu's game list?
|
- Every one of your game's folders (the folder that contains
Code, Content, Meta folders) must be stored in a specific folder. I personally use #Games
- After you have every game inside of
#Games , open Cemu and navigate to Options > General Settings
- Set the Game Directory at the bottom of the window to your
#Games folder. Cemu should update your list after you close the window.
- If one or more games do not show up in your list, they have a missing, incomplete, or corrupt Meta folder. The Meta folder must be complete for the games to show.
|
Keys for my Keys.txt file?
|
- Required for WUD and WUX games. Keys are required in Cemu's
keys.txt file before the games will boot. Obtaining keys: [ Click Here ]
- Not required for RPX format games.
|
What is the difference between WUD, WUX, and RPX format games?
|
- WUD is packaged Wii U games, encrypted. Keys are required in Cemu's
keys.txt file before the games will boot. Obtaining keys: [ Click Here ]
- WUX is the same as WUD format but compressed to substantially reduce the file size. Keys are still required.
- RPX is an extracted game as a single folder labeled after the game, with 3 internal folders,
Code, Content, Meta . Does not require any keys. Takes the least amount of storage space or equal to WUX.
|
Controller Setup?
|
- The
Options > Input Settings menu will let you configure a controller.
- If your controller does not show up in the respective dropdown menu, try switching between Xinput and DirectInput. Xinput is recommended.
- Controllers with pressure-sensitive triggers will only work correctly by using Xinput. DirectInput will not let you use both triggers at the same time.
- You must type in a name before you can save the controller profile.
- Player 1 should almost always be set as Wii U Gamepad, as this is what Wii U games typically expect.
- Every other player should likely be a Wii U Pro Controller.
- It is expected you map your buttons as they would be placed on the Wii U Gamepad. If you don't remember the layout, I suggest Googling a photo of the controller.
- And no, remapping the controller buttons differently from what's on the Gamepad will not change what they look like or are named within the games.
|
Can I use a Keyboard & Mouse?
|
- Yes, though it's highly discouraged; cameras in games will never react 1:1 with your mouse, they are meant for joysticks.
- The most up to date guide is in text by BelowDust on Discord, it includes the files as well: [ Click Here ]
- Alternatively you may follow BSoD Gaming's Keyboard & Mouse video, though out of date: [ Click Here ]
- This guide requires extra files, review this text document: [ Click Here ]
|
Motion controls in games?
|
- The default method is to click Cemu's screen and use your mouse to control motion sections, however this is a huge pain.
- With Cemuhook added to support Motion Feedback from controllers and other devices, you may check the Motion Controllers & Cemuhook section.
- Supports Android Devices, iPhones & iDevices, Dualshock 3 & 4 controllers, and possibly a few others.
|
Cemu Problems:
Cemu refuses to open at all.
|
- This should only happen if you do not have
vc_redist_x64 installed from Cemu's website. Make sure this is installed.
- Cemuhook may cause this to happen if it's corrupt, try removing keystone.dll & dbghelp.dll - if this works, try redownloading & replacing them.
- Make sure your PC isn't blocking the .zip and .dlls of Cemuhook; to check, right-click and check their Properties. Unblock them if this is true, replace the ones in your Cemu folder.
- Virus scanners can affect Cemuhook causing this to happen; try disabling them before running Cemu.
- 32bit PCs will not be able to run Cemu.
|
Text in games is missing or glitched.
|
- Cemuhook must be added to Cemu and you must used the SharedFonts link placed at the bottom of Cemu's window when opened; this adds open-source text replacements Cemu will use.
- Some games do not have correct text regardless, you will have to wait until newer Cemu versions resolve this.
- AMD Vega GPUs are notorious for messing up text, I do not know of any workaround.

If you're testing our Vulkan build, please keep in mind bugs are very common. You may report these on Discord in our #patreon-testing channel, meant for Vulkan - https://discord.gg/5psYsup
- Cemu is an experimental emulator, that said a lot of games are not fully supported and may not boot.
- If you're using an Intel iGPU, these GPUs are not supported and are likely to experience a variety of problems that AMD and Nvidia do not have.
- If it freezes or crashes while playing the game, make sure to try using Single Core Recompiler in the game's GameProfile; most games do not support Dual or Triple.
- Make sure you are not storing your Updates and DLC in your Game Directory that you set in
Options > General Settings as the Update and DLC will replace the Base Game executable.
Note: If the base game is overwritten in the Game List by the Update or DLC, it will cause the game to fail to boot.
Updates and DLC must be stored somewhere outside of your Game Directory.
- Make sure the game is supported & working for others, check the [ Cemu Compatibility Page ]
- If your Cemu version is supposed to work, the game is updated, and you're still experiencing the issue you may try the following:
- Verify all of the settings for Cemu are set up correctly by following the Recommended Settings section of this guide to a T.
- Absolutely make sure you have installed the latest update for the game.
Check the game for recommended settings or bugtesting submissions on it's Compatibility Page: [ Click Here ]
Check the Issue Submissions on Cemu's Bug Tracker: http://bugs.cemu.info/issues
- Check graphicPacks: Disable all graphicPacks made for the game except for Crash fixes. Test the game.
- Check shaderCache: Open your Cemu folder and temporarily rename your
shaderCache folder. Test the game.
- If this resolves the issue, delete
Cemu\shaderCache\Driver and Precompiled . If this does not resolve it, review your Log & find your shaderCache ID, delete it in your shaderCache\Transferable folder.
- Updating GPU Driver: Try updating your GPU driver. Test the game afterwards.
If you did a clean install, you will have to set the settings for Cemu in the GPU Driver Control Panel again.
- Fixing Corrupt GPU Driver: Download DDU (Display Driver Uninstaller) and boot into Windows Safe Mode with Networking. Uninstall your GPU driver & install the latest after.
You will have to set the settings for Cemu in the GPU Driver Control Panel again.
- Fixing Corrupt Game: Attempt to redump the base game, update, and DLC of the game and set them back up with Cemu.
If you continue experiencing problems you may try getting help from our Discord Community: https://discord.gg/5psYsup
When asking for help, please provide your Log (log.txt) from within Cemu's folder, after you have booted the game.
Note: Opening Cemu again will erase the log and you will have to come across the problem again. You may try sending a log after you reach the game's Title Screen.
Without a log, we often cannot find the problem. We will often ask for the log, but we prefer you provide it without us having to ask.

Game is horribly stuttery and freezing repeatedly.
|
- All games must build a shaderCache before blissfully smooth gameplay can happen. This happens automatically as you play. The stuttering will become less frequent the longer you play.
- Cemu will load the shaderCache each time you boot the game. After a GPU Driver or Cemu update this compile time will be roughly 10~20x as long since the older copy became invalidated.
- If Cemu begins to act as if there is no shaderCache, ensure no ghost Cemu / Wii U Emulator processes are running. To check, open Task Manager and go to the Details tab. Restart Cemu afterwards.
- You may also try to restart your PC to make sure there are no program conflicts from background processes.

ShaderCache FAQ
|
- Can I turn shaderCaches off for better performance? -
- ShaderCaches are absolutely required for games to run. You cannot disable these and you would gain nothing if you could.
- Where can I get a shaderCache? -
- We do not distribute shaderCaches because they contain copyrighted code and it would become a legal concern for Cemu. You should build your own, otherwise you'll likely encounter problems.
- I think my shaderCache is causing a problem -
- Sometimes you may need to see if your shaderCache is causing your problems or a crash; to test this, temporarily rename your shaderCache folder in Cemu's folder and test the game.
- Cemu loaded the game immediately and skipped the shaderCache when I have one -
- If Cemu is acting as if there is no shaderCache, ensure no ghost Cemu / Wii U Emulator processes are running. To check, open Task Manager and go to the Details tab. Close every instance & restart Cemu.

Audio is all crackly & fuzzy.
|
- If you cannot maintain a rock solid framerate that the game expects, the audio may become distorted. In this case, the only way to fix it would be to reach the FPS necessary.
- Sometimes this can be alleviated by changing the Audio Latency in
Options > General Settings > Audio in addition to trying either DirectSound or xAudio.
- If neither of these solutions work, then it likely is not going to be fixed by you playing around with anything.
- Some games simply have bad audio support within Cemu for now and this will not be fixed until newer Cemu versions release.

Breath of the Wild Questions:
What are the best performance settings for Breath of the Wild?
|
- The Recommended Settings section covers the best settings for every game as the settings are universal.
- The best settings for your GPU are also covered in Recommended Settings.
- The recommended graphicPacks are covered in the GraphicPacks section.
- Aside from this, as long as you have set them correctly, there is next to nothing else that you can do aside from overclocking your CPU.
|
What are the best graphicPacks to use with Breath of the Wild?
|
Grabbed from the Graphic Pack section for your leisure:
Recommended for Average Users -
Applicable GPU Fix Packs - Do not enable fix packs that are not labeled for your GPU.
Clouds - Fixes the heavily stretched clouds in the sky.
LWZX Crash
FPS++ - ( Make sure to extend the options by clicking the [+] )
(Cemuhook and the Latest Game Update must be installed!)
Dynamic Gamespeed - 32 or a less value if preferred.
Fence Method - Performance, if buggy try Accuracy.
Set FPS Limit - 60 or 30FPS, 30 is the Native Wii U framerate.
NPC Stutter Fix - If you disable GX2DrawDone() you can use this, but you will still need GX2 when using the Camera Rune.
No Depth of Field - Only recommended for performance stability, otherwise user preference.
Clarity - Preset: User preference, use the Reload Shaders button to preview.
Anti-Aliasing - Preset: "Nvidia FXAA" - if you get grayscale color, use "Enabled AA" preset.
Resolution - Preset: 1080p or 1440p
Shadows - Preset: Medium or High

Will my PC be able to run Cemu / Breath of the Wild? At 60FPS?
|
- The Requirements section covers what type of hardware is recommended for Cemu.
- The FPS you will obtain within games is determined primarily by your CPU, secondly your GPU, next being your RAM. A lot of Wii U titles only reach 30FPS unless patched by the community.
- Breath of the Wild can make use of the Dual & Triple Core Recompilers, so if you have a supported CPU, you should enable this or suffer the consequence of bad performance.
- Ensure you have followed the Recommended Settings section, readers that skim info & speed-read never win. GPU settings must be set correctly for correct performance.
|
Why is Breath of the Wild stuck at 20 or 30FPS?
|
Note: This is specifically for people who are LOCKED to 20 or 30 FPS and do not get more or less FPS.
- Make sure your PC isn't blocking the .zip and .dlls of Cemuhook; to check, right-click and check their Properties. Unblock them if this is true, replace the ones in your Cemu folder.
- Virus scanners can affect Cemuhook causing this to happen; try disabling them before running Cemu.
- It's likely you didn't follow the Recommended Settings section and skipped stuff like a noob.
- If this just started recently, ensure no ghost Cemu / Wii U Emulator processes are running. To check, open Task Manager and go to the Details tab. Close every instance.
- See here: http://compat.cemu.info/wiki/File:Task_Manager.png
- Cemuhook must be updated to the latest version or a version that is supported by the version of Cemu that you are using.
- You must ensure FPS++ is enabled by toggling it's 4 graphicPacks from within the graphicPack menu of Cemu.
- To change the framerate cap from 30 to 60 or otherwise, highlight the
Set FPS Limit graphicPack and then select which Preset you wish to use.
- You absolutely must have the latest update for the game installed.
- To dump your Update/DLC from your Wii U and install them on Cemu you may follow: [ Getting Started Guide ]

I'm having a problem in Breath of the Wild, please help!
|
- First of all, disable all GameBanana mods if you installed any as they can cause the game to screw up if they conflict. Test the game again.
- My FPS is low even after following all of the suggestions here - There isn't much else you can do besides overclocking your CPU, you're hardware limited. If you're on an AMD GPU, wait until Vulkan is public.
General Issues:
- The map cursor will not move - Please do not enable FPS++ and Static FPS together. We suggest only using FPS++, rather than Static FPS.
- The water is white / like milk - Try decreasing your resolution and restarting the emulator; do a search around the internet to find other solutions.
- Using a Rune freezes/crashes the game - Try enable GX2DrawDone() or you may consult the Discord Server for more help.
- The game freezes at some other random place - Your game files are likely corrupt and need replaced. Delete the base game & replace it; install the update & dlc again with fresh copies.
- Something in the game does not show up at all - Such as a sheikah pedestal or a puzzle piece in a shrine/divine beast - Corrupt game files, same as above.
- The Sheikah Slate Camera rune is glitchy - Enable
Options > General Settings > Graphics > GX2DrawDone() - This will reduce performance but fixes the rune functionality.
- I'm seeing glitchy textures after a cutscene happened - there's no definitive fix for this. Save and reload the game or restart the emulator entirely.
FPS-related Issues:
- My cursor in menus is going too fast - Cap your FPS to 72 at the very most, not above that; recommend 60.
- The Gerudo Desert boss flies outside of the fighting arena - Cap FPS to 30, finish the fight.
- The game freezes during a cutscene - Cap FPS to 30, finish the cutscene.
- Enemies don't get knocked back after being attacked - Cap FPS to 30, any FPS over that will reduce knockback by a percentage. Over 60FPS, knockback becomes negative.
- Some objects do not float or move in the water - Cap FPS to 30, this is a physics related issue.
- Shield surfing feels sluggish compared to the console version - Cap FPS to 30, this is a physics related issue. At 60FPS the intensity is x2, slowing you down.
- Sailing on a raft with a Korok Leaf is extremely fast - Cap FPS to 30, wind physics are twice as powerful at 60FPS.
- Enemies are spazzy and freaking out - If you cannot maintain good framerates, such as 20 or above, this may frequently happen.
