Jagex Launcher ¹⁾
Old School RuneScape ²⁾
Legacy Java Client

2024/07/01: The Legacy Java client's .jar and RuneLite's .jar were both tested to log-in and work fine when symlinked from the C++ client's osclient.exe and launched from Jagex Launcher; no need to change the client type in Jagex Launcher
2024/07/01 Anything below this line including notes for Legacy Java and RuneLite anywhere aren't up-to-date yet

2023/07/23: The legacy Java client is deprecated! (news post)
2023/07/23: These notes won't work with the current linked Jagex Launcher folder since there's not a previous OSRS Java install present and these notes are mainly here for historical reference; see the C++ version instead!
TODO: The Java legacy option shows in Jagex Launcher if the old OldSchool.msi (non Jagex-Launcher/Java) is installed; presumably the Java version can still work in 2024, but wine is still needed for Jagex Launcher

This allows running the Jagex Launcher through wine, while keeping OSRS ran natively through java
Jagex Launcher in this context is used for the account authentication, and passes the log-in session data to the OSRS client
Jagex Launcher can be closed after pressing Play and the OSRS client window appears ³⁾
2023/07/23: This cannot be installed along-side the C++ version with current notes since they share the same Wine Prefix location; TODO: Change Wine prefix names for OSRS Java

Prerequisites

Notes

i915 on GNOME 44 shows notable tearing on OSRS when rotating the camera from Xorg, but not Wayland

Install

Dependencies

wmctrl is used to toggle between windowed and fullscreen states

sudo dnf install java-11-openjdk wmctrl && sync

Jagex Launcher

You need to supply your own Jagex Launcher files as the installer doesn't work ⁴⁾

Icon

The icon provided from the macOS .dmg is higher-res than the one in the Windows .msi
.icns isn't a valid image file format according to Freedesktop.org Specifications so this isn't in the standard icon folder
