Even using CEMU, the pre-existing fan-made Wii U to PC emulator, those involved estimated Zelda would take months of work, such was the size of the game and the complexities of its systems.
Fast forward two weeks later, and there has been remarkable progress.
Where previously the group could only show off the game's opening cave, a new gameplay video shows the game running almost as well as it does on Nintendo's own hardware.
The framerate still isn't quite up to scratch (a complaint you could also level at the main game), but the number of things now working after so short a time is genuinely stunning.
Combat works fine, exploration and the world's physics systems appear to function correctly, you can enter and solve Shrine puzzle dungeons, you can use the game's rune powers correctly... the list goes on.
A fortnight ago CEMU was supported by 1857 people, who collectively donated $7782 per month (around £6300). It's now supported by 5135 people, who donate nearly $22k a month (more than £17k).
