Obsolete now due to the original extension surpassing this.
Original description:
This is a browser extension that plays the Wii Shop Channel theme in the background when you visit a shopping website. The list of detectable websites is in js/site-list.js.
The extension only requires two permissions: Tabs, to check the URL of the currently-active tab, and Notifications, to show a message after the extension is installed.
This extension is not developed by, or affiliated with, Nintendo in any way.
This is a custom version of Wii Shop Extension called Advanced Wii Shop Extension which mainly adds a music selection menu, as well as new songs, more links, and more.
Custom Music
Link Editing
Assigning Songs to Links
This is a work in progress and some planned features may be scrapped.
