==Running Games in CEMU==
 
===Before opening the ISO===
 
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 romsites 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 onwards. Loadiine format is just the ISO contents unpacked as directories of files, with an executable RPX file you'll need to open in CEMU.
 
 
Your iso must be either uncompressed, compressed using WUD format, or in Loadiine format (only possible for versions 1.4.0 onwards) to boot in CEMU.
 
 
===Dumping Games and Getting Game Keys Yourself===
 
You need the game in Loadiine format (directory of files with RPX executable), the Wii U Common Key, and Uwizard. First, you use the tool [http://gbatemp.net/threads/ddd-wiiu-title-dumper.418492/ here] to create a Loadiine dump from games on your Wii U.
 
 
Open the Loadiine folder generated, then "code", then "app.xml" in your favorite text program. Copy the 16-char ID before "<title_id>", that's your Title ID. Open Uwizard and go to the "Settings" tab. Fill in the blanks with the Wii U Common Key, and if possible the other ones. Now go to the "NUS Downloader U" tab and paste that Title ID from earlier. You'll need to add the game as well. Check "Decrypt", and press "Start Download". A long log will appear, scroll down for a while and you'll find your game key under "Decrypted Title KEY".
 
 
The other way, used before to dump Wii U games, isn't public and requires hardware modding to the Wii U optical drive.
 
 
[http://www.ps3hax.net/showthread.php?t=73858 This] is the method used to get the Wii U console keys from your own Wii U, not that there's much reason to.
 
 
===Installing Updates===
 
To install updates under CEMU, you need to open the rpx file for that specific update in CEMU. Your save data will be apparently lost, that's because CEMU treats the game now that it's updated as a separate new game so you'll need to copy your games over.
 
 
In order to make that rpx file yourself, you'll need a proper version of NUSGrabber with a ckey.bin, as well a Wii U Console Key (that common key from earlier works) and a Game Key for your version of the game. Then you follow [http://www.reddit.com/r/cemu/comments/4of2x6/guide_on_how_to_update_wii_u_games/ this guide].
 
 
===Installing Downloadable Content===
 
Installing DLC is not yet possible with CEMU because of further checks done besides the presence of the DLC data that are not emulated yet. Some videos online show DLC tracks in Mario Kart 8 being emulated on CEMU, but that was just modding the base game to replace some of the base tracks.
 
 
===Controls===
 
* '''Wii U Gamepad:''' Gamepad touch control emulation can be done by holding TAB then using the mouse. Microphone is mapped to a button for now, and tilting doesn't work yet.
 
* '''Wii U Classic Controller''': Up to 7 besides the Gamepad can be connected for multiplayer.
 
* As of 1.5.5, the Wiimote isn't emulated yet.
