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. If you cannot figure this out, I suggest visiting our Discord for further assistance: https://discord.gg/5psYsup Should I edit my PC's PageFile settings for RAM usage? Why is my RAM usage low? PageFile Settings & Info: You shouldn't limit the system PageFile size as this only serves as a cap on how large it can be. If you leave it at default ("system managed",) Windows will automatically increase and decrease the size as needed. There isn't a substantial reason to cap it yourself, particularly for any emulator. If you want to change anything we only recommend to tell Windows to put your PageFile on the fastest system drive that will never be removed from your system, such as an SSD, so it reduces the time required to shuffle data around.. Much closer to RAM speeds than a standard HDD (spinning disc VS storing on NAND flash chips.) If you keep a PageFile on a HDD at 5200RPM or lower, or faulty, this can cause an emulator to buckle in loading the data and may result in "random" crashes as you attempt to load in previously used assets that were shuffled over to your PageFile on that drive.. So, faster is always much better and stable. RAM Usage is Shrinking or Small: As for RAM usage shrinking, Windows automatically shuffles and compresses currently unused assets and pushes them to your PageFile until they are called once again by the program. Unsure of how long it takes to consider it not necessary for the RAM to hold it, but it will happen gradually after loading into the games. Disabling Windows 10's Data Compression: There is a way to disable Win10s data compression so it doesn't take quite as long to use those assets again (less microstutter, you can google this though it isn't explicitly necessary), but I'm unsure if there is a way to force the cache to always be loaded into the RAM and exempt from your PageFile.. I'd have to research that again. In either case you'd have to have enough RAM at all times for that to be viable. Why is my CPU or GPU usage low? Shouldn't it be 100%? My HDD usage? TLDR: Long story short, it's uncommon for either to be maxed out for anyone except low-end PC consumers. CPU Usage: Cemu's CPU usage is maxed with roughly 5 or 6 Cores at the very most while using Triple Core Recompiler with the **few** compatible games. While using Single Core Recompiler, Cemu may use up to 3 or 4 cores where possible, however Cemu is able to function on Dual-Core CPUs with reduced performance. Whereas Cemu will use multiple cores and threads for different things, such as x3 for CPU Emulation, x1 for Audio Emulation, x1 for GPU Emulation (or multiple if the GPU supports it in its driver,) and x1 for one or other background tasks ... Cemu will likely never use 100% of all available cores and threads. It is completely normal to hover between 30 to 80% CPU Utilization, and up to 100% during the loading procedure upon booting a game title. GPU Usage: Cemu uses very little of a GPU unless you are upscaling the game. By default, games are all 720p to 1080p; this is typically a drop in the water for most modern GPUs--this is usually reflected in how little usage the GPU shows when monitored. However, usage will go up if the FPS is increased. The issue here is most console games, especially Nintendo titles, are capped to either 30 or 60FPS ... and going above this cap will cause physic issues, glitches, or crashes within those games. Since this is generally not something you want to happen, getting high GPU usage is typically only caused by upscaling the resolution or uncapping the framerate to benchmark your performance. HDD/Disk Usage is High: If your HDD usage is high, it's likely your PC is swapping previously PageFile-cached data from your RAM, back to your RAM, or vice-versa as this is a standard for systems today. If your drive is rather slow and cannot keep up with the transfer requirements, it may frequently hit 100% usage... this will usually become apparent when your PC either freezes or the game stops responding. This may cause a crash or the game may take awhile to resume. If this is indeed the case, we either recommend increasing your available RAM (through physical upgrade,) or we recommend upgrading to using a SSD or NVME SSD drive for much faster read & write times. 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

folders) must be stored in a specific folder. I personally use After you have every game inside of #Games , open Cemu and navigate to Options > General Settings

, open Cemu and navigate to 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 ]

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 ]

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 ] Can I use a phone or tablet as the Gamepad screen with touch support? Officially? No. But can you? Yes. The setup is rather simple.

Download Spacedesk both for your PC and the device you want to use as a display + touchscreen.

As long as you have your PC and the device connected to the same Wifi Network, you should be fine. Your other device will be considered a second monitor.

Open Cemu & navigate to Options > Separate Gamepad View -- This will open a separate window dedicated to the gamepad video output.

Simply drag this window and maximize it on the desktop screen dedicated to your other device. You may want to disable Cemu remembering where the window is, as if you disconnect this display, the gamepad window may be stuck over there.

Please keep in mind this will likely hit your performance, and if your phone/tablet is set to 30FPS mode it may cap Cemu to 30FPS. Tip: You can right-click your taskbar on Windows and set Taskbar to hide automatically. This will give you more screenspace on your other device. 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: I cannot find Vulkan in the Graphics Menu or it crashes Cemu after selecting it in Options > General Settings > Graphics Ensure your GPU actually supports Vulkan. You can find more information by searching online, especially when it comes to Intel GPUs.

If your GPU does support Vulkan, make sure that GPU is not being overridden by the integrated GPU while using a Laptop, usually because you're on battery usage.

Make sure your GPU drivers are fully up to date. If possible, get the driver from your PC's manufacturer if it was pre-built.

If none of this has helped, we suggest downloading the latest driver standalone installer package and DDU (Display Driver Uninstaller) After you have obtained both, restart Windows into Safe Mode. Run DDU and uninstall your driver. (Do not restart yet.) Use the standalone package to reinstall the latest driver. Once the latest driver has successfully reinstalled, reboot your PC and check to see if Cemu can use your GPU for Vulkan. The last resort is downloading the latest Vulkan Runtime and seeing if this works for you; make sure to restart your computer after installing it. https://vulkan.lunarg.com/sdk/home#sdk/downloadConfirm/latest/windows/vulkan-runtime.exe If none of this has resolve your problem, feel welcome to come by the #Troubleshooting channel of our Discord server. Discord Server - https://discord.gg/5psYsup 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.

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. When loading shaders or playing a game, it crashes or freezes. 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.

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 I'm running Vulkan with my old cache and I'm still stuttering? -

Vulkan does reuse the old cache if you tell it to, but this will not eliminate stuttering for anyone. This is because Vulkan has a required Pipeline Cache it has to generate. This stutter will persist just like before. 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 -

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, run the game and find your Cache ID in the Window Title Bar, delete it in your shaderCache\Transferable folder. You will need to delete the Precompiled and Driver folders once again. 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.

See here: http://compat.cemu.info/wiki/File:Task_Manager.png Audio is all crackly & fuzzy. Try setting the GameProfile setting for Thread Quantum to the default state of 45,000 and then test; otherwise, continue.

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.

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.
