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

• 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⁾

• Installation Video

• openSUSE Tumbleweed (GNOME) ⁴⁾
• 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⁾
• When first launching OSRS after installation, at the lobby before pressing Play Now, allow OSRS to download its full data cache ⁶⁾

• Jagex Launcher sometimes has issues with being interacted with from GNOME tray with the AppIndicator/KStatusNotifierItem support for GNOME Shell extension ⁷⁾
• 2024/04: The Jagex Launcher tray icon was fine on Xfce and KDE Plasma 6, so presumably this only applies to GNOME
