Trying to find the explanation on how to do the zips from the ropes. Can't seems to find anything. I'm new to the community maybe i'm just not looking at the right place.

Thanks for helping

The zips can only be done on Japanese SNES version. All you need to do is jump towards the rope, and press jump on the same frame Mickey grabs the rope. If done at the correct height and angle, the zip will bring you to the end of the level.

For the zips in Mad Doctor, I believe the setup is very lenient. For stairs zip in Haunted Halls, the setup would be at the third-to-last step, facing away from the rope, and grabbing the rope at the height of your jump.

Just a tiny correction, it seems you need to press jump exactly 2 frames before Mickey would have grabbed the rope. And for the Mad Doctor zips I find it works best if you immediately let go of the jump and right button as soon as you get the zip. For the zip on Haunted Halls you'll need to do it from a specific position (you can see that in any of the recent top runs here) and keep holding jump after getting the zip to get into the stairs. And for the warpless category there's also a zip on Dungeon 2: , here you'll also want to keep holding jump after the zip.

Good luck with the zips, and if you've got any more questions, feel free to ask here or on the Discord!
