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

• 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 ³⁾

• 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 ⁴⁾
• When first launching OSRS after installation, at the lobby before pressing Play Now, allow OSRS to download its full data cache ⁵⁾

• Jagex Launcher sometimes has issues with being interacted with from GNOME tray with the AppIndicator/KStatusNotifierItem support for GNOME Shell extension ⁶⁾
• 2024/04: The Jagex Launcher tray icon was fine on Xfce and KDE Plasma 6, so presumably this only applies to GNOME

• You'll need to supply Jagex Launcher files as the installer doesn't work ⁷⁾
• See Jagex Launcher Installer notes for installer testing

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