Cemuhook tutorial

i notice the new feature in citra canary, is there any tutorial on how to use this cemuhook on citra?

is this the answer to map the items and gears on OOT to ZL and ZR?


This lets you use the touch screen with DS4’s one.

The above guide is unhelpful, at least if you have peanut brain like I do. I have not been able to figure out what to enter in the server IP and port text boxes, using an USB-connected DS4, and the guide doesn’t even mention anything related.
