ROM Hack HANS-modding eShop (or other way) to get hidden titles?

[Hiccup]

How do you mod the eShop (or do something else) to let you download "unsearchable" titles? And maybe even "nonpublic" titles? It can be done. https://boards.fireden.net/vg/thread/140500048/#140502635
I'm interested in installing Best Buy demos etc and making clean .3DSs and .CIAs out of them

I've merged the threads, restored your "deleted posts" (this is not how you deal with duplicate threads! you need to use the report button) and removed off-topic.

Oh, sorry about that. Forgot about that gbatemp had a report button.
