I created an interactive map, you can find the github repo here: https://github.com/thyraxx/ssbd_interactive_map
The site is ugly, design isnt my strong suit, but it mostly works..

You can host/run it yourself on your local machine downloading from my Github, or use my online hosted version:
https://ssbdmap.mistwalker.cc/
With left click on an Icon you can view what that is (not really interesting)
With Right click you can make the Icon opaque, maybe for marking you have it or whatever, this marking IS NOT saved.

If you want to find all stars, RNG stars and secrets.
As of this time there is no explanation how to get to the secrets on the map, and typos/mistakes might be still in there.
