eXtreme shared news of a PS4 Custom Home Menu Mod proof-of-concept and PS4 XMB Hack by Senaxx.
Below are some brief details alongside a video demo and additional screenshots from fx0day and eXtreme, to quote: "Maybe you have saw on twitter that Senaxx posted a screenshot of the first custom home menu on the ps4. for me it's the most interesting progress for end users.
He found a database and was able to edit the file. It would be great if someone can share more information about the method that others can edit the home menu too and search for more ui mods."
