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 an rpx file.
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.* Download an NUS downloader such as [http://application.wiiuusbhelper.com/Updater.exe WiiU USB Helper].* Paste this URL into WiiU USB helper when prompted for the titlekey database. - https://wiiu.titlekeys.com/* Select the game you want to download, click get it and then download games.* This will download the files for the game you chose (the same as the .tik's title).

==Setting upGame Formats and Files Needed==
===Physical Dumps===
You'll first need to fill in the "keys.txt" file in Cemu's directory. It has a sample line with a bogus key and a comment, which you may as well delete.
Your file must have many lines like this, one for the Wii U Common Key (D7B00402659BA2ABD2CB0DB27FA2B656), and one line for the Game Key of each game. Sharing these keys isn't exactly safe legally, but ROM sites at least share [http://pastebin.com/GWApZVLa the Game ones]. Note that for games using the Loadiine format, you won't need a Game Key at all, but those will need Cemu versions from 1.4.0 onward.
Your ISO must be either uncompressed, compressed using WUD format, or in Loadiine format (only possible for versions 1.4.0 onward) to boot in Cemu. Here's a [http://docs.google.com/spreadsheets/d/19WV2YQvS2PkiHnQTlYP7cE2eHOPl06Rx4tCvfud_Hpw/edit?pref=2&pli=1#gid=0 compatibility list]. Dump your discs using [https://gbatemp.net/threads/wudump-dump-raw-images-from-a-wiiu-game-disc.451736/ Wudump].
===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 Support===
[[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). HereThere's a recent regularly updated complete set of the official ones ([https://mega.nz/#F!Z4UWVIYS!HsOvjW4tUMHE40ECIG7sMQ March 2017]) but there's are 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 Amiibo support in CEMU Cemu is incomplete right now and not all figurines are compatible yet - though incompatibilities may be caused by bad Amiboo Amiibo dumps as well. ==Setting Up Cemu==
===Controls===
At startup, Cemu cannot go online or connect 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 a real (erase it if any problems or emulated) [[Nintendo 3DS emulators|3DS]]crashes when compiling shaders at startup occur.
==Troubleshooting/Speeding up==
===Shadercaches===
Shaders are normally cached as you play the game. This can cause a lot of stutter stutters 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.
[[File:Shadercachestuff.png|thumb|Some settings in the Nvidia control panel might help.]]
===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.
===Disable Hyperthreading===
Cemu may not be programmed well with hyperthreading. To disable it, go into the Task Manager, right -click cemu.exe and then set these affinities:
[[File:Processor_affinity.png]]
==Graphics Packs==
To work around emulation bugs and other problems the way [[Dolphin]] does, "Graphic Packs" are title-specific property sheets which defines define 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 godraysgod rays, 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:
==Issues==
* Save states aren't getting implemented any time soon. This has a lot to do with the complexity of the Wii U memory layout and architecture, as well as the huge file size. As a result, the current developers are not interested in implementing them.
* The emulator is still unfinished and unoptimisedunoptimized, as noted in the lack of efficient and stable H.264 video decoding, causing glitchy videos. This is worked around with Cemuhook entirely, but its approach to video decoding is unlikely to be taken into the emulator.
===Piracy===
