PS3PATCH.PUP files contain a firmware PKG file, named here "patch_data.pkg" or "patch_data.spkg", that is an incremental firmware update. This [[Certified File]] is encrypted and signed using "PKG keyset" for PS3 3.55 and lower System Software versions, and "SPKG keyset" for more recent firmwares.
Just a simple SCE pkg file. For decryption we need to use spkg keyset (for 3.56+ firmwares) or pkg keyset (for 3.55 or lower firmwares)
 
It seems to follow the same path and permissions description scheme as .spkg_hdr.1 files. See [[Spkg_hdr.tar|Spkg_hdr.tar, Signed Firmware Package headers]].

PS3PATCH.PUP, that can be extracted using [[PUP]] tools.

For example, <pre>dev_flash/vsh/resource/silk_webkit/:775</pre> points to the /dev_flash/vsh/resource/silk_webkit folder and when extracting, will give it 775 (drwxrwxr-x) permissions.

See [https://web.archive.org/web/20141118222850/http://pastie.org/private/ycka0sxjqq9ncjj5yhbrtq] for PS3 4.60 CEX patch_data.spkg decryption.

(no need to post more samples, one old pkg and one spkg sample of each is enough to reduce pagelength - see also {{talk}} page)
