@LightningMods on my 4.55 PS4 Testkit FAT, trying to do some modifications.
So, I go to /system/priv/settings and found some XML files (pictured below).
I open them, trying to do some modification and replaces them. After that, I went to the Debug Settings --> Boot Parameters and saw a new thing that I never seen before.
This is called vsh_4k_mode.
After a reboot it disappear.
So I open up the files and as you can see I saw the vsh_4k_mode on the XML but I still don't know how I enabled it
Also in the ***s document the mode never appear
Same for all theses settings !
Also on my Twitter you'll find a PlayStation File Archive I used for my database at PSX Times.
