Help with large entrances

I have two large entrances that unfortunately do not work and I'm not quite sure how to get them to. One of them I haven't finished drawing entirely so excuse the crudeness of the second image but the first one I don't understand at all. The tile type is right and I thought I was setting the entrances in the proper location but it's still not working.

In the third image I'm showing a tree entrance that has never worked (based on the legends of hyrule graphics) so if anyone has any idea how to get these working that'd be great.

Perhaps HM has saved the wrong coordinates (?). Have you checked these entrances out in a hex editor?

I'm pretty sure he meant those special big entrances you can create in the overworlds.

You probably didn't used the right blocks to create them. Remember that you have to used the same block numbers as in neonswift exemple in the compendium or Parallel Worlds (that big cavern/entrance in the main village). Analyze how the entrance blocks are made and you should figure it out. If not I can do it for you in 3~4days once my usual three days weekend begins

I'll take a look at those and see how it goes!
