Last month we saw the release of a Windows PC application called OrbisTitleMetadataDatabase by PlayStation 4 developer @RedEyeX32, and today he announced on Twitter he's added the PS4 Orbis Title Metadata Database source code to Github for developers. :santa:

Like Santa flying off into the night bidding everyone farewell, Red-EyeX32 also let sceners know, to quote: "This is probably going to be my last release ever." :nolove:

Download: Github Source Code

Also today PlayStation 4 developer @zecoxao shared some PS4 4.05 filesystem usermodules patch offsets (below) on Twitter, while IDC offered some corrections as well.

To quote from the README.md file: OrbisTitleMetadataDatabase

4.05 offsets to decrypt SOME usermodules, patch the following entries:
Code:
to decrypt SOME usermodules, patch the following entries: *(uint8_t *)(kernel_base + 0x360600) = 0x31; *(uint8_t *)(kernel_base + 0x360601) = 0xC0; *(uint8_t *)(kernel_base + 0x360602) = 0xC3;
Correct patches to enable mmap of all SELF (discard previous patches):
Code:
*(uint8_t*)(kernel_base + 0x31EE40) = 0x90; *(uint8_t*)(kernel_base + 0x31EE41) = 0xE9; *(uint8_t*)(kernel_base + 0x31EF98) = 0x90; *(uint8_t*)(kernel_base + 0x31EF99) = 0x90;
PS4 themes are interesting: they're driven by a basic scene definition (in XML) which points to models (MDX files) and textures (DDS files). The scene definition defines what objects are where and how they animate. And images for UI icons too.
When you have a theme active, they're mounted to /mnt/sandbox/pfsmnt like games are, so you can look at their files the same way as everything else.
Thanks to both @raedoob and @Wultra for the heads-up on this news in the PSXHAX Shoutbox earlier tonight! :kitty:

They are for developers to be able to decrypt some of the PS4 4.05 filesystem usermodules... for the rest of us, just cheering them on. (y)

I think we covered this before, but for those who missed it when THESE things happen then we will, for now all we can do is root for the PS4 Devs and download away. :D
