Nubix - Source Code Offer / Corresponding Source
=================================================
Nubix is free software, licensed under the GNU General Public License, version 3
only (GPL-3.0-only); see LICENSE. The PS5 binary (nubix.elf / homebrew package) is
statically linked against the third-party libraries listed below. As required by
section 6 of the GPLv3, the complete Corresponding Source for every binary release
is published next to the binary, at the same place and at no further charge:
https://github.com/JBuildr/nubix/releases
Release asset: nubix-v<version>-corresponding-source.tar.xz
(e.g. nubix-v0.3.0-corresponding-source.tar.xz for Nubix 0.3.0)
Checksum: nubix-v<version>-corresponding-source.tar.xz.sha256
Manifest: nubix-v<version>-corresponding-source.MANIFEST
The archive contains:
- nubix-v<version>-src.tar.xz : the Nubix source tree the binary was built from,
including patches/libdatachannel-*.patch, docker/Dockerfile, CMakeLists.txt,
cmake/ and scripts/ (the complete build and installation scripts);
- upstream/ : the unmodified upstream source of each library in the table below,
as release tarballs (sha256-verified against the pinned sums) or as
`git archive` exports of the exact commits;
- MANIFEST and SHA256SUMS : sha256 and size of every file in the archive.
The archive is produced by scripts/make-source-bundle.sh (in the Nubix source).
By default that script packages the current working tree
(`git ls-files -co --exclude-standard`, i.e. tracked files including uncommitted
changes plus non-ignored untracked files; docs/ is excluded), or a given git ref
(--nubix-ref <ref>) or directory (--nubix-dir <dir>).
How to rebuild the PS5 binary
-----------------------------
1. Build the toolchain image (Ubuntu 24.04 + clang/lld 18 + the prebuilt
ps5-payload-dev SDK and libraries from pacbrew-repo release v0.40.2):
docker build -t ps5dev docker/
2. Build libdatachannel v0.24.6 (+ submodules), with patches/ applied:
scripts/build-deps.sh ps5
(set LDC_LOCAL_SRC=<dir> to use the libdatachannel sources from this archive
instead of cloning from GitHub; extract all libdatachannel/libjuice/libsrtp/
usrsctp/plog/json archives from upstream/ into one directory first.)
3. Build Nubix:
scripts/build-ps5.sh
The result is written to build-ps5/.
The libraries in /opt/ps5-payload-sdk inside the image were built by the
ps5-payload-dev project from the PKGBUILD recipes in pacbrew-repo v0.40.2
(included in upstream/) with the ps5-payload-sdk toolchain (also included). To
rebuild one of them from the sources in this archive, use its PKGBUILD
(directory named after the port, e.g. ffmpeg/, SDL2/, curl/) with the
ps5-payload-sdk and pacbrew (makepkg) as described in pacbrew-repo/README.md,
pointing source= at the tarball/export from upstream/.

Not part of the Corresponding Source (GPLv3 section 1 "System Libraries" / generally
available tools): the PS5 system modules the binary is dynamically linked to at
runtime (libkernel, libSceLibcInternal, libSceNet, libSceVideoOut, libSceAudioOut,
libScePad, libSceUserService, libSceSystemService, libSceImeDialog, libSceKeyboard, ...;
the SDK only ships link stubs for them), and the compiler/linker used (clang/lld 18
from Ubuntu 24.04, see docker/Dockerfile).
Evidence for commits not pinned by a version tag
------------------------------------------------
pacbrew-repo v0.40.2 builds the SDK, the SDL2 fork and x264 from git branch heads
(sha256sums=SKIP). The exact commits were determined from the prebuilt
ps5-payload-dev.tar.gz of release v0.40.2 (as installed in the ps5dev image):
* pacbrew-repo: tag v0.40.2 = commit 1687e82 (2026-08-18); the next commit on the
repository is dated 2026-08-30, i.e. after the build, so the recipes used are
exactly those of the tag. The release asset ps5-payload-dev.tar.gz was
(re)built 2026-08-23 ~14:18-16:11 UTC (file mtimes in the SDK: 2026-08-23 14:18 UTC;
asset upload 16:11:56 UTC; release note "rebuild with latest SDL2 port").
* SDL2 PS5 fork: PROVEN. libSDL2.a contains the revision string
"SDL-2.30.12-ga47182a20" (SDL_GetRevision). Commit a47182a20e74... (2026-08-22,
"ps5: adjust remote control keyboard mappings") is on branch release-2.30.x-ps5;
the next commit is dated 2026-09-24, after the build.
* x264: PROVEN. libx264.a contains "r3222 b35605a" (X264_POINTVER 0.165.3222) and
x264.pc reports Version 0.165.3222; the stable branch head is
b35605ace3ddf7c1a5d67a2eb553f034aef41d55 (abbreviation b35605a is unique).
* ps5-payload-sdk: INFERRED, strongly supported. The SDK records no commit id. The
SDK's master branch at the build time (2026-08-23) was 4eb701204fc3 (2026-08-02,
"add support for firmware 13.60"); the next commit is 8e125899 (2026-08-28).
The installed crt1.o contains the firmware 13.60 offset added by 4eb7012
(data offsets 0x28C9E80, 0x0D9C064, 0x314B510, 0x2098228) and lacks kernel_iommu_* symbols introduced
by the 2026-08-28/29 commits; libc.a lacks killpg() (added 2026-09-03).
libc++/libc++abi/libunwind in the SDK are built by that commit's libcxx.sh from
LLVM 18.1.8.
* Release tarballs: versions from the v0.40.2 PKGBUILDs (pkgver=) and cross-checked
against the installed pkg-config files (FreeType reports libtool version 26.1.20 =
2.13.2; openlibm.pc reports 0.8.0 because upstream's Make.inc in the v0.8.6
tag still says VERSION = 0.8.0 - the PKGBUILD pins v0.8.6 with sha256). The archive's tarballs are
verified against the sha256sums in those PKGBUILDs; FFmpeg's PKGBUILD has
sha256sums=SKIP, so its sum (bce9eeb0f17ef8982390b1f37711a61b4290dc8c2a0c1a37b5857e85bfb0e4ff)
was computed on download and recorded in the MANIFEST.
* libdatachannel: v0.24.6 tag with the submodule commits recorded in that tag
(git submodule status of the build checkout). The Nubix patch
patches/libdatachannel-xbox-pli.patch is applied on top at build time.
