About
Dusklight is an unofficial native PC port of The Legend of Zelda: Twilight Princess (GameCube), developed by the TwilitRealm community team on top of the zeldaret/tp decompilation project — 5.5 years of community decompilation work. It is the first major GameCube decompilation-based PC port to ship, widely considered a landmark release equivalent in scope to what Ship of Harkinian was for Ocarina of Time. Confirmed platforms include Windows, macOS, Linux, Steam Deck, Android, and iOS.
Features include an unlocked framerate, native gyro and mouse aim, Mirror Mode, a built-in achievements system, a built-in speedrun timer, 4K texture pack support, seven graphics backends, and support for nine disc image formats. First released v1.0.0 on May 9 2026; actively updated to v1.4.1 as of June 2026. Requires the player to supply a Twilight Princess GameCube disc dump.

⚙ Setup notes
No Proton needed: Dusklight ships a native Linux x86_64 build packaged as a single AppImage (e.g. Dusklight-v1.4.1-linux-x86_64.AppImage, downloaded from the TwilitRealm/dusklight GitHub releases). In Desktop Mode, mark it executable (chmod +x or right-click → Properties → Permissions → Is executable) before adding it as a non-Steam game. When using Steam's "Add a Non-Steam Game" picker, set the file filter to All Files so the AppImage shows up.
Install: On first run the game will prompt you to locate your Twilight Princess GameCube disc dump. Nine disc image formats are supported (ISO, GCZ, and others) so most dump methods work. Use CleanRip on a Wii to legally dump your disc if needed.
Features: The port delivers an unlocked framerate (easy 60fps on Steam Deck), native gyro and mouse aim support, Mirror Mode (now accessible on Deck), a built-in achievements system, a built-in speedrun timer, and 4K texture pack support via seven selectable graphics backends.
Significance: This is the first major GameCube decompilation-based PC port to ship and is considered a landmark release — equivalent in scope to what Ship of Harkinian was for Ocarina of Time.

The one thing to know
Supply your own copy: Requires a GameCube disc dump of Twilight Princess. Use CleanRip on a Wii to dump your disc legally. Nine disc image formats are supported (ISO, GCZ, etc.) so most dump methods work.
AppImage gotcha: The Linux/Deck download is a single AppImage (named like Dusklight-vX.Y.Z-linux-x86_64.AppImage), not a bare Dusk executable. Mark it executable in Desktop Mode first, and set the "Add a Non-Steam Game" picker to All Files so it appears. Some distros also need libfuse2.
Mirror Mode: Unlockable on Steam Deck.
Status: As of June 2026 (v1.4.1) the port is actively updated and Steam Deck support is first-class. First release was May 9 2026 — community Deck reports are still early but very positive.

Community guides
Write-ups and threads from people who got this (or a similar) game running. deckport links to them — it doesn't reproduce them.
Get the artwork
deckport never hosts game images. Open this game on SteamGridDB, pick
the cover / hero / logo / icon you like, and drop them into the
game folder under .deckport-art/ before you push it to the
Deck. The importer files them under the right names automatically.
Run it on your Deck
Two files: the one-time importer (deckport.py) in your
Deck's home folder, and this game's install helper. Copy the game
into ~/Games and run the helper with Steam closed — it
writes the recipe (binary, launch options)
and registers the shortcut with artwork.
