PCSX2 - not launching - October 26th, 2023

Note: The information below is now irrelevant. Update PCSX2 to the latest version. A workaround has been included in the emulator to ensure PCSX2 works on systems with older libraries. You do not need to revert PCSX2 to an older version. The below will be kept to explain specifically what happened.

You do not need to revert PCSX2 to an older version.

A recent update of PCSX2 also included updates to its required libraries. With the stable version of SteamOS being nearly a year old, SteamOS' libraries are now outdated. Without these updated libraries, newer versions of PCSX2 will not work. In order to continue using PCSX2 on Stable SteamOS, you will need to revert to an older version to continue playing.

Here's How

  1. Download pcsx2-v1.7.5129-linux-appimage-x64-Qt.AppImage from: to your /home/deck/Downloads folder
  2. Rename pcsx2-v1.7.5129-linux-appimage-x64-Qt.AppImage to pcsx2-Qt.AppImage
  3. Move the downloaded emulator from Step 1 to /home/deck/Applications and overwrite the current pcsx2-Qt.AppImage file
  4. Right click pcsx2-Qt.AppImage, click Properties, click Permissions, check Is executable
  5. Your games will now launch using v1.7.5129, stay on this version for the foreseeable future

Note: Although SteamOS Preview (SteamOS 3.5 as of October 26th, 2023) does have slightly more updated libraries than SteamOS Stable (SteamOS 3.4 as of October 26th, 2023), these libraries are still too old for the latest versions of PCSX2. It is uncertain whether or not a SteamOS 3.5 dot release (Ex - SteamOS 3.5.1) or SteamOS 3.6 will include the prequisite libraries for the latest version of PCSX2 to run.

RetroArch does not work anymore - April 30th, 2023

  2. Click Update (x) in the bottom left
    • There will usually be a number in the ()
