====== Information ======

  * Old School RuneScape ((http://oldschool.runescape.com))
  * :!: Java; see [[games:wine:old_school_runescape_jagex_launcher_c|New C++ Client]] notes for the modern GPU-accelerated client

===== Prerequisites =====

  * [[distros:fedora_workstation_gnome|Fedora Workstation]]

===== Notes =====

  * :!: 2023/06/19: There are no known configurations where ''-Dsun.java2d.opengl=true'' offers a performance benefit
  * :!: 2020/03/24: On macOS, using the official ''.dmg'' to install OSRS resulted in the worst possible performance due to a mix of forced GPU acceleration and Retina with Java 8; it was recommended to manually install OSRS and to use the latest OpenJDK package available instead to workaround this
  * ''-Dsun.java2d.uiScale'' at 2 and higher increases all UI scale in-game, and improves performance with lowering texture resolution

==== Copyright Footer ====

  * ''jagexappletviewer.jar'' from ''OldSchool.msi'' was used because it allows the copyright footer bar to be removed upon logging in (([[https://github.com/rsu-client/rsu-client/commit/b2553e5aeca9a0e6b271b5b17eee9a57c8d6ef11|rsu-client commit]] and [[https://github.com/rsu-client/rsu-client/issues/127|initial bug report]])) ((the previously used direct-link ''jagexappletviewer.jar'' can be found [[http://oldschool.runescape.com/downloads/jagexappletviewer.jar|here]]))
  * :!: The copyright footer was **not** hidden with OpenJDK 12, 13, and presumably any JRE newer than 11 if ''jagexappletviewer.jar'' comes from ''OldSchool.msi'' ((last tested 2019/10/22))

====== Install ======

  * ''wmctrl'' is used to toggle between windowed and fullscreen states
  * ''p7zip-plugins'' is needed to extract ''jagexappletviewer.jar'' from ''OldSchool.msi'' later ((only ''7z'' can do this properly and **not** ''7za'', ''cabextract'', nor ''unar'')) ((this is expected to already be installed from the Fedora prerequisite))
  * :!: As of 2023/03/17, Java 19 didn't work on Fedora 37, but 11 is still fine

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

  sudo apt install openjdk-11-jre wmctrl && sync

==== Show Java Paths ====

  * Useful for specifying Java 11 in the launch script below instead of changing it system-wide

  sudo update-alternatives --config 'java'

==== 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 [[https://specifications.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html|according to Freedesktop.org Specifications]] so this isn't in the standard icon folder

===== Testing =====

==== jagexappletviewer.jar ====

  * :!: ''jagexappletviewer.jar'' has varying filesizes depending on where it's sourced from, along with different functionality depending on the host operating system ((see the [[#copyright_footer|copyright footer notes]] above))

=== Windows ===

  * Extracts ''jagexappletviewer.jar'' from ''OldSchool.msi'' and requires ''7z''
  * Places it at ''~/Downloads/windows-jagexappletviewer.jar''

  rm -Rf '/tmp/oldschool' && mkdir -p '/tmp/oldschool' && wget -O '/tmp/oldschool/OldSchool.msi' 'https://www.runescape.com/downloads/oldschool.msi' && 7z e -o'/tmp/oldschool/OldSchool-msi' -y '/tmp/oldschool/OldSchool.msi' && 7z e -o'/tmp/oldschool/rslauncher-cab' -y '/tmp/oldschool/OldSchool-msi/rslauncher.cab' && cp '/tmp/oldschool/rslauncher-cab/JagexAppletViewerJarFile'* ~/'Downloads/windows-jagexappletviewer.jar' && rm -Rf '/tmp/oldschool' && sync

=== macOS ===

  * Extracts ''jagexappletviewer.jar'' from ''OldSchool.dmg'' and requires ''7z''
  * Places it at ''~/Downloads/macos-jagexappletviewer.jar''

  rm -Rf '/tmp/oldschool' && mkdir -p '/tmp/oldschool' && wget -O '/tmp/oldschool/OldSchool.dmg' 'https://www.runescape.com/downloads/OldSchool.dmg' && 7z e -o'/tmp/oldschool/OldSchool-dmg' -y '/tmp/oldschool/OldSchool.dmg' && cp '/tmp/oldschool/OldSchool-dmg/jagexappletviewer.jar' ~/'Downloads/macos-jagexappletviewer.jar' && rm -Rf '/tmp/oldschool' && sync

===== Android =====

  * TODO

  am start -n 'com.jagex.oldscape.android/.AndroidLauncher'

  am force-stop 'com.jagex.oldscape.android'

===== Windows =====

==== Create Directory ====

  * Alternatively, use Explorer to make the ''runescape'' folder in the ''User'' folder and ''runescape\oldschool''

  if not exist %UserProfile%"\runescape\oldschool" mkdir %UserProfile%"\runescape\oldschool"

  start %UserProfile%"\runescape"

==== Java ====

  * Download the Windows ''.zip'' of the latest Java package from https://jdk.java.net/
  * Extract the root folder from the archive and drop it in the ''runescape'' folder
  * Folder structure should be ''%UserProfile%\runescape\jdk-14''
  * ''javaw.exe'' should exist at ''%UserProfile%\runescape\jdk-14\bin\javaw.exe''

==== jagexappletviewer.jar ====

  * Extract it from the macOS ''Oldschool.dmg'' installer
  * Should reside at ''%UserProfile%\runescape\oldschool\jagexappletviewer.jar''

==== Batch File ====

  * Should reside at ''%UserProfile%\runescape\osrs.cmd''
  * The usual command-line arguments above can be tossed in or altered as-needed

<code>
cd "jdk-"*"\bin"

start javaw.exe -Djava.system.class.loader="app.systemclassloader" -Duser.home="..\..\oldschool" -Djava.class.path="..\..\oldschool\jagexappletviewer.jar" -Dcom.jagex.config="http://oldschool.runescape.com/jav_config.ws" -Dhttps.protocols="TLSv1.2" -Xms"768M" -Xmx"768M" -Dsun.java2d.uiScale="1" "jagexappletviewer" "oldschool"</code>

===== macOS =====

  * need macOS dmg .jar
  * Need OpenJDK 13 or something in the ''~/runescape'' folder
  * OpenJDK 9 had GPU usage and lower FPS
  * Need ''-Djava.system.class.loader=app.systemclassloader''
  * :!: This //very// likely needs refactored
