The inclusion of "Steam Deck" in your search query suggests a misunderstanding of how these systems work.

Users have reported that ZukoStore can cause system instability, such as freezing or making it impossible to enable HEN.

This article is for educational and informational purposes only. Downloading copyrighted PKG files (games) that you do not own is illegal in many jurisdictions. Modifying your PlayStation 3 to run custom firmware or HEN violates Sony’s Terms of Service. Proceed at your own risk.

Note: Some PKG games require a RAP license file (usually found alongside ZukoStore downloads in a separate .rap package). Place those in dev_hdd0/home/00000001/exdata/ .
