The Legend of Zelda: Breath of the Wild released for the Wii U and the Nintendo Switch on Friday, March 3. By Sunday, it was running in , a Wii U emulator that's been in development since 2015. Cemu developer Exzap posted a short video of Breath of the Wild's opening on Reddit, showing remarkable progress for a brand new game in a relatively young emulator. Where plenty of games can't get past the opening menu or crash on boot, here was Breath of the Wild running on a PC with an i7-4790K and a GTX 780. That's the good news.
The bad news is that 'running' and 'playable' are very different things, and Breath of the Wild is crawling along at about 10-15 frames per second in Exzap's video. Emulating a console is an incredibly complex process, and throwing more horsepower at the game won't be enough to make it run smoothly. 'Audio is muted because it is just white noise,' Exzap wrote on reddit. 'Lots of bugs that make the game unplayable. Physic glitches, rune abilities that require object selection don't work, no water collision, etc. Essentially it's impossible to leave the tutorial area without using a save.'
My dreams of emulating Breath of the Wild at 4K, 60 fps? Not exactly crushed, but most definitely delayed. I reached out to Exzap to find out how much work it took to get Breath of the Wild to work in Cemu, how he did it so quickly, and how long the road to full compatibility will be.
Surprisingly, it took only a few hours to get Breath of the Wild to boot in Cemu—it didn't take a lot of specialized work to make it run at the most basic level in the emulator. 'The game pretty much ran this way out of the box after the few issues were resolved that prevented it from going in-game. I was actually very surprised to see it running this good with no extra work required,' Exzap wrote.
Exzap pointed out that Cemu emulates the Wii U as a piece of hardware. But different games use that hardware in different ways, so 'getting a specific game to run, like BotW, means that we look into what the game does differently from other games and why it fails.' Exzap wrote that 'BotW was missing certain rarely used OS API functions that caused the game to softlock after the menus.' That was a relatively quick fix to bring the engine up and running.
Understanding the ins and outs of a piece of hardware as complex as the Wii U is a process that can take years. The GameCube/Wii emulator Dolphin, which has been in open source development since 2008 (and around since 2003) only recently reached the milestone of . Some emulator development will improve performance and compatibility for all games, while some fixes more accurately emulate specific attributes of the original hardware that individual games used in a particular way. I've previously written about to some games with new code.
For Breath of the Wild to run at its intended 30 frames per second, Cemu will likely need both general and specific improvements. Exzap wrote that it was too early to say what Breath of the Wild will need, specifically. 'I don't yet know precise details about why the game is running slow,' he wrote. 'That said, CPU bound games usually profit from improvements to the recompiler/JIT core. Additionally, Cemu is rather young so there is also optimization potential almost everywhere in the code. My guess is that we will see small incrementals in speed for almost every future Cemu release.'
Right now, Link's suite of rune abilities don't work at all in Cemu, enemies sometimes fall through floors, grass often doesn't render and lighting effects are wrong. And those are just the obvious issues. There are likely smaller, more nefarious bugs hiding in Breath of the Wild's vast world, and there's a very good chance that Nintendo used its hardware in ways no other Wii U game has before. I asked Exzap if he's already encountered anything interesting about how Breath of the Wild was programmed, and he said one thing did stick out.
'Every public technical specification about Wii U states that the GPU only supports 16 texture mapping units per shader stage. Yet, BotW uses up to 18 in some cases. So in a way the game pushes the hardware beyond what we assumed where the hard limits.'
Anecdotally, I've noticed while playing Breath of the Wild on Wii U that it takes an unusually long time to load after pulling up the OS's Home menu. I'm no engineer, but it seems like Nintendo might be using memory typically allocated to the OS, just to eke out every bit of performance they can. Even then, Breath of the Wild's framerate dips into the low 20s in some busy scenes. Ideally those performance problems will disappear in Cemu, but only time will tell.
A bit more good news, though—because Breath of the Wild is heavily CPU limited, which is common in emulation, running it at resolutions higher than its native 720p should have little impact on performance. Exzap wrote that he expects Zelda to perform similarly to Xenoblade Chronicles X, which Cemu users have been able to run just as well at 4K as they have at 720p.
But how long will it take until Breath of the Wild is playable at full speed, without all those bugs and the inevitable ones that haven't been discovered yet? I knew putting a date to that goal would be impossible, so I asked Exzap how optimistic he was about getting there. Weeks? Months? Years?

'Giving ETAs on anything is always very difficult,' he wrote. 'A lot of emulation development is just research, like figuring out why softlocks occur or why a specific graphic effect is broken. It's impossible to know the amount of time required to come to the solution if both the cause and the solution is not known. The most realistic answer I can give is that it will take AT LEAST several weeks to fix the remaining problems. But it could take years as well. Also, there is this common misconception that because the game runs so well already, it will run perfectly equally soon. In reality, there is no correlation.'
The next build of Cemu, 1.7.3, releases on March 10 . Here's an indicator of just how hostly anticipated emulation of Breath of the Wild currently is: since the end of February, Cemu has picked up nearly 400 new backers and increased monthly donations from around $5900 to $7400 per month.
Recently, a friend told me that she has no clue about computers but wants to play BotW, so I wanted to help her out, and while doing it I realize that she can't be the one... I'll sort that out for people that just wants to play BotW (EUR) but doesn't wants to spend hours trying to figure out how it all works.
24 July 2017 update: This tutorial is outdated for MONTHS now, I wouldn't use it myself. Find a new one please.
The data in here is just in case anyone wants to play the bugged outdated version full of crashes.
Before Starting:
At the moment of last edit, this is a 1.7.4d CEMU tutorial.
Emulating is not perfect, there are a few bugs that crashes the emulator, but we are getting there on each version and the CEMU team is fixing them at a good pacing. If you crash, you can just load a previous savefile (it's not a problem because botw autosaves on average each 5 minutes) and not trigger them whatever that you did to crash it. Also, we don't know when the CEMU will natively run cinematics and videos, and until we are going to need to use a plugin for it.
Breath Of The Wild Iso Download For Cemu Windows 7
Stuff you need to download first:
Download the Zelda Breath of the wild game on Loadiine format. Choose your own website if you want, I'll just provide 2 random links in case you don't trust other websites.
-From here, this Link. It's a torrent file, you need a torrent program like Qbittorrent to download it.
-Alternative download here (click on the top right yellow button to skip the Ads and download the torrent file).Download the 6.6k ShaderCache from here.
-You can get other caches here on the CEMUCaches subreddit but any 10+k shader pack is likely to be corrupted.Download the Wii U emulator (CEMU) from the official website: http://cemu.info/
Download Mapple Seed version 2 from official place: https://github.com/Tsume/Maple-Tree/releases
What to do with those files:
Extract CEMU on any folder (if possible close to computer root, something like C:CEMU1.7.4d).
Extract the zelda game on a folder with not a long or weird name. Games won't launch if you use non-american characters like Ñ for example. (If possible, put the folder close to your hard-drive root, like C:CEMUGamesZeldaBotW).
-It's very important to have the game and the emulator on an easy pathing or the games won't even load.Extract the zelda ShaderCache into the 'C:CEMU1.7.4dshaderCacheTransferable' folder of the emulator.
Open Maple Seed and it first will ask you to set find the CEMU emulator file, so choose that. Then it will ask for the games folder, set that up also. When it's open and it scanned your games, just right click on Zelda breath of the wild and click on Update.
-Note: If no games appear, make sure you downloaded the Loadiine version of the game (which is easy to know because it contains 3 folders code/content/meta instead of a .wud file) and make sure your mapleseed pathing to get games is ok. You can reset the mapleseed pathing on users/appdata/roaming/mapleside at a .ini file.
-Videoguide of it: https://www.youtube.com/watch?v=d2fOq1uJorkAfter it's updated, right click and add the DLC (if it appears, no need if not). After that, you can close Maple Seed, or launch the game with it, but it's a bad idea to launch it for the first time since you need to configure the stuff in the next section of this tutorial (and sometimes launching from maple seed doesn't even works).
Proper way to configure everything now:
Launch CEMU emulator, go to options, and put the region of the console in whatever language it better suits you.
Go to options and choose input settings, then configure a controller like WiiU Gamepad. You can play with the keyboard of the pc or with a controller of another console, or whatever you want. Just make sure you set the input properly.
Go to File to load the zelda game that you downloaded. Go to where it's extracted, inside the Code folder you need to open the file .rpx (that is the game, even though is probably named U-King).
Your computer will have to compile the ShaderCache that you have downloaded and adapt it to your graphics card and processor (so you have an idea, which this does is to pre-render all the textures of the game to your computer specs so you do not stutter while playing). It may take a few long minutes and freeze your computer, but only the first time it runs. After it has succesfully compilled them the next times you play it will never take more than 1-2 minute to load the shaders already pre-compilled.
Play, have fun, enjoy.
Troubleshotting with the CEMU files:
Daemon Tools
When you open up the game with CEMU, pay attention to the window title, at the top. There should be something like 'SaveDir: blablabla'. That's the name you need to use for this game files, make sure to rename your shaderCache transferable file to fit it.
Also your savegame files will have that name, in case you ever need to backup them (the saves should be automatically stored at C:CEMU1.7.3d/mlc01/emulatorSave).
Tips for gameplay:
If you ever have to use the touch screen of the Wii U, use the mouse of your computer. Wherever you click it is as if you did it on the touch screen, and hold right click to rotate stuff. But you will not need it except once or twice in the game.
To name horses just use your keyboard to name it, press + on the gamepad and then press Enter.
If you get camera lock in a shrine, re-load a save from menu.
If you get sudden 1FPS bug, press start and save and load (or load if u can't enter menu).
Do not climb flag poles or top of trees, they make the game freezes (at 1.7.4d).
Temporary Video Plugin:
On 1.7.4d, the CEMU can't load Botw cinematics or videos, so there's a plugin that helps with that. Download from https://sshnuke.net/cemuhook/ . You must put it on the cemu folder: C:CEMU1.7.4d). Just leave the file in there.

How to update to new CEMU versions:
If you are using an outdated CEMU version and you want to update, there is important things that you want to copy over before deleting the outdated version.
After downloading the new version, extract the files in a folder next to the other version to keep consistency. Now, open the outdated folder and copy the next files to the new version.
The shaderCache/transferable folder. Or just the transferable cache of your game (remember, the ID of the game is the SaveDir that appears at the window title).
Your savefiles from the folder mlc01emulatorSave. (that's right, saves are stored into the emulator folders, so you need to copy your savegame to the new emulator version).
The update of the game, which is something that MapleSeed did for you the last time, but now you need to do manually. The entire update goes into the folder mlc01usrtitle so copy that to the new version. (Yeah, the ID is different here, for updates and DLC the CEMU uses different IDs than for savegames and shadercaches, no worries).
Also, you may want to copy input settings files or the keys.txt file.

And that is it. You should now have your savegames, shadercaches and the game dlc/updates installed in your new shiny emulator. Test if everything works fine before deleting the outdated one, don't be a dick and delete your savegame before testing if it works in the new version xD.

Finally: Now that you can play, want to play it smoother?
You pirated the game, congrats. However, a lot of improvement to zelda FPS can be achieved, this link might help you: https://www.reddit.com/r/cemu/comments/633x0u/cemu_zelda_fps_guide/ just please do not mention piracy on there as it's on the official CEMU sub-reddit and they don't support piracy.
