    Because information about CEMU in 21:9 started to grow from everywhere without a real guide, I decided to write it step by step. I post it here and will be a copy of my other post on Reddit. I started earlier, but because BotW was not supported, I didn't. Now it is, so here is how to do it ;)

    Feel free to share your codes for other games.

    CEMU 1.8.0

    Let's start with The Legend of Zelda : The Wind Waker HD

    * 1 Launch CEMU and select "Options > Fullscreen scaling > Stretch"

    [​IMG]

    * 2 Launch your game (in our exemple, Wind Walker HD) and select "Tools > Memory searcher"

    [​IMG]

    * 3 In the top box, search for 1.77777777 (float is selected) and double click on the one with address "0x1004aaf0" to add it in the bottom list (this address will change regarding of your game, check at the bottom of this post) (http://i.imgur.com/wkm07D0.png)

    * 4 In the bottom list, click "freeze" the item you just added, then click on the value to edit it, and change the value with 2.37 (2560x1080) or 2.38 (3440x1440).

    * 5 Download a 1440 pack of your game: https://github.com/slashiee/cemu_graphic_packs/tree/master/Quality and open the rules.txt with a text editor. Change all 2560 by 3440. (This step is to get a native 3440x1440 3D when fullscreen will be activated, otherwise the 2560 will be stretched, and the game less sharp)

    * 6 Your 3D is now "deformed".

    * 7 Just switch in fullscreen mode, and here is the result ;)

    Notes:

    +As you can see, all 2D elements cannot be (for now) converted. Only the 3D is 21:9 adapted.

    +When you don't have the address, just scan during the game, edit all the 1.77777777 value with 2.37 or 2.38 until you find the one who correct the ratio. Note that some games need to load a new game to apply the change.

    +Leaving CEMU will reset this setting.

    For now, and as I said, all 2D elements are not 21:9 converted. But result is quite impressive on a 3440x1440 screen ;) I'll deal with a squashed radar.

    Searching for 1.77777777 in Smash EUR for me doesn't give that addres, instead I can try others, and eventually find the one which works. This has to be done each stage though, which is quite unconvenient. Is there any way to manually edit that addres, without knowing its value first?

    That's a really great idea! Searching for the aspect ratio in memory, I should try it with some PS1 games.

    Gambia, The
    Question regarding Xenoblade Chronicles X with 21:9. The best Cemu Version for XBX is 1.7.2 at the moment. Can somebody confirm that this method works?
    https://github.com/slashiee/cemu_graphic_packs/issues/56#issuecomment-305346703
    I can confirm its working with the latest Cemu Release, but with 1.7.2 its crashing at this point:
    • press F6, click yes. right click the only item on the list and NOP it. press OK
    Would be nice if someone could help me here, want to play XBX in 3440x1440 in 21:9. :)
