CEMU Cemu supports either physical games dumps in WUD, or compressed WUX format, as well as game dumps converted to the Loadiine format. Loadiine games come as multiple directories with game files and a rpx file.

===Digital Copies===
Nintendo's servers are poorly secured due to a huge oversight when designing Wii U/3DS software protection. As such, with tickets proving you bought the game (but which you can get through less legit ways), there are downloader utilities like NUSGrabber, FunKiiU, UWizard, or jnus among others, and decryption tools like UWizard and CDecrypt, to obtain a functional copy. The process of how to exactly acquire those files is detailed elsewhere on this wiki.
===Updates and DLC===
Prior to 1.7.3, only updates were supported though pasting update files on the main game's folders (keeping in mind the main game is in Loadiine format) and overwriting any files. DLC wouldn't work at all through this method, though with some specific games there were workarounds and some could play DLC tracks in Mario Kart 8 through swapping of specific files. From 1.7.3 onwards, proper support for DLC and updates was included in CEMUCemu.
Use the same process as above to download updates. Once decrypted, simply copy and paste these over the original game's files.
* Run the game at least once.
* Check Cemu's log.txt file and look for a line that says "Mounting local storage (AOC): .\mlc01\usr\title\NUMBERS\NUMBERS\aoc\"
* Add (create) folders with the same name as the above (substituting the "NUMBERS" bit with the actual numbers) in your "CEMUFOLDERCemuFOLDER/mlc01/usr/title" folder.* Add any updates (which must be added first) you want to the "CEMUFOLDERCemuFOLDER/mlc01/usr/title/NUMBERS/NUMBERS/" folder.
* Create a folder named "aoc" and put the DLC files into there. The "code", "content", and "meta" folders of the actual game itself also go in the "aoc" folder.
Amiibo are hard-to-find figurines unlocking various on-disc content in select 3DS and Wii U games. They use the NFC technology. Nintendo Amiibo data is distributed online as NFC tags (.bin files). There's a regularly updated complete set of the official ones but there's also unofficial spoofed packs on various other sites.
Recent versions of CEMU Cemu include Amiibo support. Simply go to NFC / Scan NFC Tag from file, and load the relevant .bin file. Keep in mind Amiboo support in CEMU Cemu is incomplete right now and not all figurines are compatible yet - though incompatibilities may be caused by bad Amiboo dumps as well.
==Setting Up CEMUCemu==
===Controls===
Since ver 1.11.5, Cemu added non-native support for Wiimote controllers, implemented by using keyboard or USB controllers.
Using this is completely optional.
Download [http://sshnuke.net/cemuhook/ the latest version] compatible with your CEMU Cemu version, unpack it to the same directory as cemu.exe and right-click on dbghelp.dll, check Proprieties, Digital Signatures tab, select a signature and press Details. This should make it no longer crash at start-up. Make sure you also have the latest GPU driver installed, as well as both x86 and x64 versions of the [http://www.microsoft.com/en-US/download/details.aspx?id=53840 Microsoft Visual C++ 2015 X64 Redistributable].
Whenever you boot CEMU Cemu now, this cemuhook tool is enabled by default and offers various additions for better motion control emulation, or some graphical hacks that greatly enhance Zelda BOTW in particular. Accept to download the missing shared fonts as well to make text in some games (Super Mario Maker among others) display correctly.
Enabling "GX2SetGPUFenceSkip (HACK)" enhances graphical emulation in BOTW in particular. A pre-installed Graphical Pack that comes with recent versions of Cemuhook, "LWZX Crash Workaround", as well as the "GX2DrawDone()" option under Experimental, should help with some general crashes specific to BOTW.
===Shader Caches===
When your game is loaded, check for its ID on the titlebar in front of "SaveDir:" and note it down. The directory where transferable shader caches are stored is <code>.\Cemu\shaderCache\transferable</code>. They're generated the first time you play through a game and at that time cause noticeable stuttering. You can download a complete cache from places like [http://www.reddit.com/r/CEMUcachesCemucaches/comments/7bv7el/complete_shader_cache_collection_1110c_v2/ here] and rename them to match your game version's ID to spare yourself most of that unpleasant experience. Just keep in mind that shader caches from versions older than 1.8.0 are incompatible with later versions of CEMUCemu.
At startup, CEMU Cemu will prepare a compiled version of that cache under <code>.\Cemu\shaderCache\precompiled</code> and that one depends on your GPU driver, so you might want to erase it if any problems or crashes when compiling shaders at startup occur.
==Troubleshooting/Speeding up==
Shaders are normally cached as you play the game. This can cause a lot of stutter and slow the game down.
Cemu accepts other shader caches that can be traded online. You can go to [https://www.reddit.com/r/CEMUcachesCemucaches/ /r/CEMUcachesCemucaches] and search for the ones you want. It's often very difficult to generate a complete cache for large games, and will not completely eliminate stuttering.

===Native H.264 Decoder===
MP4 videos are often encoded for Wii U games with the expectation that the hardware plays it back on-the-fly, but because the x86 architecture is not PowerPC, this is resource-intensive for Cemu since it has to run the PowerPC video decoder. An unofficial utility called [https://sshnuke.net/cemuhook/ CEMUhookCemuhook] bypasses this by playing H.264 video directly from Windows codecs that are programmed for x86.

==Graphics Packs==
To work around emulation bugs and other problems the way [[Dolphin]] does, "Graphic Packs" are title-specific property sheets which defines advanced settings you might not be able to change in the interface. Basic rendering options including shadow resolution and quality, post-processing effects like bloom, lighting and godrays, custom anti-aliasing, and such can be applied here. You can even use them to ''reduce'' the internal resolution for an increase in the framerate. This is not to be confused with '''Texture Packs''', which are replacement textures; CEMU Cemu doesn't support that, but it is planned.
The "Graphic Packs" themselves are folders under the <code>graphicPacks</code> directory. They can be named anything, but they should contain the "<code>rules.txt</code>" file. A bare-bones example of a "Graphics Pack", called "Bayo_1080p", would look like this:
