Olibiakos: nope is not that

The Theme Shop was added in [[9.0.0-20]], which allows users to purchase [[Home Menu/Themes|Home Menu Theme]]. The shop file structure is based on the [[BOSS]] file. When the shop starts booting, it requests a top file from https://npdl.cdn.nintendowifi.net/p01/nsa/dMtiFHzm5OOf0y2O/thmtop/<countrycode>/<language>/top. Because Nintendo has closed the Shop alongside [[eShop]] on March 27, 2023, the Top file was edited to only have "New Themes" as an option.

== Available Themes Info ==
After the top file, when you click any Theme Category or All themes, the 3DS Downloads the available themes for the country on https://npfl.c.app.nintendowifi.net/p01/filelist/dMtiFHzm5OOf0y2O/thmdtls?c=<countrycode>&l<language>=&a3=<indexCount>
