• Jagex Launcher ¹⁾
• Old School RuneScape ²⁾

• This allows running the Jagex Launcher through wine, while keeping OSRS ran natively through java
• This is a result of Jagex not caring about Linux users ³⁾
• 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 ⁴⁾

• Fedora Workstation
• Wine

• wmctrl is used to toggle between windowed and fullscreen states

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

• This needs installed on a Windows machine first, and then the Jagex Launcher folder in Program Files can be copied as-is to the Wine prefix
• Google Drive link to a clean Jagex Launcher folder

mkdir -p ~/'.wine' && WINEPREFIX=~/'.wine/Old School RuneScape' WINEARCH='win32' wineboot && sync

gio open ~/'.wine/Old School RuneScape/drive_c/Program Files'
