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). May I suggest that you choose your own region where possible, so the download is quicker (from your regional servers).* Now we need to convert the game into Loadiine format so that you can load it in Cemu. Simply right click your newly downloaded game, then click "Prepare for Emulation".* Load the .rpx file from [Your gamelocation]/code/[yourgame].rpx with cemu.

==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.
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.

===Updates and DLC===
===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 also unofficial spoofed packs on various other sites.
Recent versions of 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 is incomplete right now and not all figurines are compatible yet - though incompatibilities may be caused by bad Amiboo dumps as well.
==Setting Up CEMU==
===Controls===
The Wiimote still isn't emulated yet, but you can have up to 8 GamePads set in the menu.
* Microphone: Spoofed, a configurable key simulates blowing on the mic.
That said, Cemuhook's latest versions support [http://sshnuke.net/cemuhook/padudpserver.html binding the Wii U GamePad motion controls] to a controller that supports Gyro controls (such as a Dualshock 3/4, a Steam Controller, or [http://play.google.com/store/apps/details?id=com.innoventions.sensorkinetics compatible] smartphones). Another tool called [http://forum.cemu.info/showthread.php/140-WiimoteHook-Nintendo-Wiimote-Cemu-support-Wii-Wheel-for-Mario-Kart-8-edition WiimoteHook] supports binding them to a real Wiimote. Cemu cannot go online or connect to a real (or emulated) [[Nintendo 3DS emulators|3DS]]. ===Cemuhook===Using this is completely optional. Download [http://sshnuke.net/cemuhook/ the latest version] compatible with your 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=52685 Microsoft Visual C++ 2015 X64 Redistributable]. Whenever you boot 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/CEMUcaches/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 CEMU. At startup, 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.
