If you've never heard of the CEMU emulator before, you might want to look it up now. The Wii U emulator for PCs is funded through Patreon and is currently supported by around 1800 people who donate about $7782 per month (at the time of writing). It is a spiritual successor to Dolphin, a GameCube emulator. The reason we're talking about it right now is because the developers behind it are working hard to bring The Legend of Zelda: Breath of the Wild into the fold of supported games.
They have The Legend of Zelda: Breath of the Wild running on their Wii U emulator already but it “plays” much as to be expected for the early days of its emulation. The frame-rate stays within the 10-15fps mark, and there are bugs throughout the game. The CEMU developer, Exzap, said, “Lots of bugs make the game unplayable. Physic glitches, run 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.”
For now, there isn't much there to being able to play The Legend of Zelda: Breath of the Wild through CEMU, but there is hope! Exzap had this to say about a potential full release, “Giving ETAs on anything is always very difficult. A lot of emulation development is just research, like figuring out why soflocks occur or why a special 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.” Would you play The Legend of Zelda: Breath of the Wild on PC if you had the chance?
