• Jagex Launcher ¹⁾
• Old School RuneScape ²⁾ (for RuneScape/RS3, see these notes instead)
• C++ Client
• Installation Video ³⁾

• This allows running the Jagex Launcher and the C++ OSRS clients through wine
• Jagex Launcher can be closed after pressing Play and the OSRS client window appears ⁴⁾

• Fedora Workstation
• Wine

• On the first OSRS client launch, it may start an invisible game window; Close osclient.exe and re-launch it from Jagex Launcher ⁵⁾
• Jagex Launcher sometimes has issues with being interacted with from GNOME tray with the AppIndicator/KStatusNotifierItem support for GNOME Shell extension; disable it ^{6) 7)}

mkdir -p ~/'.wine' && WINEPREFIX=~/'.wine/Old School RuneScape' WINEARCH='win64' wineboot && WINEPREFIX=~/'.wine/Old School RuneScape' winetricks 'discord_game_sdk=disabled' && sync

• You need to supply your own Jagex Launcher files as the installer doesn't work ⁸⁾

• Google Drive link to a clean Jagex Launcher folder with SHA256
• Use this if at all unsure

• 2023/09/16: The installer doesn't launch a GUI and seemingly can't be silently-installed
• See Jagex Launcher Installer notes for testing

• Update launcher if prompted, log-in, select OSRS → New Official Client → Install
