The cover, in its box
The cover art appears mounted on a 3D box, next to the game’s name. It works for digital-only releases too.
Every game on the shelf gets its cover.
Coverly Shelf is a browser extension that puts the box art in a 3D case and a screenshot gallery on every 3DS title page on hShop. It only changes how the page looks: everything else stays the same.
Free and open source (AGPL-3.0). For Chrome, Edge and Brave; a Firefox version will follow.

What it adds to every title page
hShop title pages list the name, the product code and a description, but no pictures. Coverly Shelf uses that code to find the game’s cover and screenshots and places them next to the text.
Full-size screenshots
A gallery of screenshots and the title screen. They open full size and you can move through them with the keyboard.

At home in light and dark
It follows the page’s colours and type, in light mode and dark mode, so it looks like part of it.
It only changes how it looks
The extension leaves everything the page does alone. Here is what it can and cannot do.
It never touches downloads
It only adds pictures. It does not change links, buttons or anything you download.
If something fails, the page is untouched
No cover found, or the image sources are unreachable: it adds nothing and the page looks as it always did.
Only the permissions it needs
Remembering in your browser which images it found, so it does not ask again, and reading images from two sites. Nothing else.
No tracking, no account
No analytics, no sign-up, no server of its own. What you browse stays in your browser.

Turn on Developer mode
Open
chrome://extensions(edge://extensionsin Edge,brave://extensionsin Brave) and switch on Developer mode.Load the folder
Click Load unpacked and pick the folder, or drag the folder straight onto the extensions page.
Open a title page on hShop
The cover and screenshots appear on their own, with nothing to set up.
Questions
Why is it not on the Chrome Web Store?
It has not been submitted yet. Until then you install it by hand from GitHub, built from the same code you can read in the repository. When it is published, this page will say so.
Which sites does it work on?
On hShop title pages (hshop.erista.me/t/…). On every other site it does nothing. Coverly Shelf is an independent project, not affiliated with hShop or Nintendo.
Does it change anything about downloads?
No. The extension only adds pictures next to the page’s text. It does not read or change links, buttons or files.
Does it send data anywhere?
No. It only requests images from art.gametdb.com and thumbnails.libretro.com, and remembers in your browser’s storage what it found for each game. There are no analytics and no account.
What if a game has no cover?
It tries other regions and sources; if it finds nothing, it adds nothing and the page stays as it was.
Is there a Firefox version?
It is planned. Once there is a tested build, it will appear in the GitHub releases and on this page.
Is it free?
Yes. It costs nothing, needs no account and its code is AGPL-3.0.
Where the pictures come from
GameTDB
Covers come from GameTDB, a community-maintained game database. The images belong to their owners.
Libretro
Screenshots and title screens come from libretro-thumbnails, the Libretro project’s thumbnail archive.
Part of the Coverly ROMs family
Coverly ROMs does the same for the ROMs on your SD card: it finds the missing covers and adds them.
