About
Old School RuneScape is the free-to-play revival of the iconic 2007-era RuneScape by Jagex, relaunched in 2013 and actively maintained with community-voted content. The Steam Deck path uses the Bolt Launcher (Flathub) paired with the RuneLite open-source client, delivering a native Linux experience with plugin support, HD options, and far better performance than the default launcher. No Proton is required — Bolt and RuneLite both ship true native Linux builds.

The one thing to know
- Native Linux path via Bolt + RuneLite — no Proton needed. Do NOT use the official Jagex Launcher; it requires Wine/Proton and has historically broken on Deck updates.
- Install Bolt Launcher from Flathub in Desktop Mode via Discover before adding to Steam.
- Bolt's source repo moved from GitHub (archived Nov 2025) to Codeberg; the Flathub build (com.adamcake.Bolt) remains the install path and is unaffected.
- Add Bolt as a non-Steam game: binary = flatpak, launch options = run com.adamcake.Bolt.
- Community controller layout "Simple OSRS" by G00dspeed is widely recommended — search for it under community layouts after adding the non-Steam shortcut.
- OSRS is free-to-play; members content requires a paid subscription from jagex.com.
- The OSRS Wiki Steam Deck guide is kept up to date by the community — check it for any Bolt or RuneLite version-specific changes before first setup.
- On-screen keyboard is occasionally needed for chat; bind a button to bring up the Steam keyboard overlay.

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.
