Library sources and artwork

Polaris owns the host Library. Nova presents that Library on Android and keeps each title’s launch choices, artwork, and home-screen shortcut attached to its canonical app identity. Two entries with the same display name do not become the same game.

Where entries come from

Steam and configured apps

Polaris keeps the configured app identity and launch command. A title can use provider artwork without changing how it launches.

Heroic GOG and Epic

Polaris 1.4.0 imports native and Flatpak Heroic entries with the matching store, runner, installation, and app identity. Refresh the host Library after Heroic installs or removes a title.

Built-in utilities

Entries such as Virtual Display use artwork shipped by Polaris. They do not automatically search game providers and inherit an unrelated game cover.

Manual curation

A choice made in Artwork Studio wins over automatic and built-in matching until the player clears or replaces that custom match.

Fix missing or incorrect artwork

1. In Nova, open the title’s game detail page and choose the compact Artwork Studio action.
2. Use Refresh automatic artwork when the source identity is correct but the cached art is stale.
3. Search the exact title, review the candidates, and choose Apply Selected Artwork when an automatic match is not good enough.
4. Use Clear the custom artwork match to return the entry to its automatic or shipped artwork policy.

Non-Steam provider searches require a SteamGridDB API key configured in Polaris. The key enables search; it does not change the game’s launch identity or command.

Alan Wake 2 is installed but has no poster

Refresh Polaris’ Heroic scan first and confirm the entry carries its Epic or GOG source. Then reopen Nova’s Library and use Artwork Studio. If search is empty, verify the SteamGridDB key on the host before changing the app command or creating a duplicate entry.

Virtual Display shows game artwork

Polaris 1.4.0 replaces an old automatic provider match with the shipped Virtual Display poster. A deliberate manual Artwork Studio choice is preserved; clear that custom match if you want the built-in poster back.

Home-screen shortcuts

Nova’s Pin to Home Screen action uses the artwork currently selected for that game. The action reports Pending and Pinned state rather than presenting every tap as a new request. Changing Library artwork does not change the game identity; repin the shortcut when you want Android’s launcher copy refreshed.

What Reset Game Profile changes

Reset Game Profile is for the title’s launch preferences. Artwork curation and home-screen pinning have their own explicit actions so a launch reset does not silently become a Library cleanup operation.
