First of all, there's a Wii U emulator for PC called CEMU. They have been working on emulating The Legend of Zelda: Breath of the Wild onto the program. This version of Breath of the Wild is obviously the Wii U version, not the Switch version of the game.
Emulation is a sticky process. Consoles tend to have locked framerates (usually 30 or 60 for today's consoles) while PCs can clock whatever FPS it can comfortably pump out (and the game allows, of course). Because of this, getting something with a different integrity to run properly on a PC is difficult. For those unaware, an emulator is quite literally a digital version of a console. You're not running Breath of the Wild on PC. You're running Breath of the Wild on a Wii U… housed on a PC.
Originally, this project wasn't able to render much past the opening cave sequence, as framerates started fluctuating to render on the "Wii U". The people involved in the CEMU project thought it would take months to work on the game, considering the vastness and complexity of the game itself, but they've made some amazing progress in a matter of two weeks.
Combat, exploration and the game's physics works correctly and it's progressing even further. CEMU works on donations. Previously working on a budget of $7782 a month, the team now gets $22k a month after they started work on Breath of the Wild.
For a look at their progress so far:
