I don't know the proper name for this, so sorry :p

I know that Pheenoh was testing it on stream a few weeks ago, and there was potential for getting it to do something in ems. I haven't seen anything on discord, has any progress been made in finding other places to activate it than just Kakariko and hacks?

Also, is there any luck in getting epona into North Faron?

Probably best to ask in the discord. We messed with the "Fake World" glitch as we called it, but not with much success yet. We basically need to find a way to get there without entering a human loading zone as wolf....and have no clue how yet.

Epona in North Faron would only be possible by getting the Epona Ledge Clip we do in Hyrule in South Faron. Since Faron is loaded all at once in TPHD, we could ride oob all the way to N.Faron. But sadly the ledge in S. Faron is super small, so we couldn't manage to clip there yet.
