I'm using these maps (https://www.neoseeker.com/legacy-of-ys-books-i-ii/faqs/) to play YS 2, but they appear to differ a bit from the MSX version. In order to get to the waterway key, I need to enter Underground section 3 on that map, it claims the entrance is behind door nr. 32 in the temple of Fact(o), but that leads me to what in the maps is called section 2, letter J.
I have tried every door I could find in all the six temples, but I'm baffled by this. Does anyone know the above ground door that will lead me to the Waterway Key?
