I would like to inquire Developer's Services about Pertaining to PlayStation 3 Trophies.
I have recently found @Bucanero Developments with the Console regarding Trophy and Game Save Resigning Via Console, rather than on a Computer.
Seeing as there are very few Developers left working in the PlayStation 3 Scene, especially in regards to Trophy Development, I was wanting to know how much it would cost in order for someone to look into NPComm Signature. I'll use 'NPComm' for short.
As noted here:
https://webcache.googleusercontent....om/ps3/Trophy_files+&cd=1&hl=en&ct=clnk&gl=us
NPComm begins with the prefix "B9DDE13B"
This sequence has a length of A0, as noted with this example:
When First Installing a Game, the NPComm is Found in the EBOOT.
This is true for both PS3 and PSV Games, but once the Trophy Set via TRP is installed, the NPComm can also be found the TROPTRNS.DAT of the resultant Trophy Folder. The NPComm is required in order to load a Trophy Set, as well as to sync it. Without it, a TRP and a Trophy Folder are useless...
If you notice, an unpacked TRP does not include the TRNS file or anything similar.
While a Trophy Folder does not include TROPCONF.SFM. There is a false one, that is really the TROP.SFM found in the TRP, but there is not TROPCONF as seen in the TRP, that is in the folder.
This is what a TROP.SFM within a TRP looks like:
This is what a TROPCONF looks like:
Now, both the TROPCONF and TROP have differing TRP signatures.
But since TROPCONF is not present in the Trophy Folder, I feel this is related to NPComm.
It is my suspicion that a person can derive the NPComm from the TRP signature and vice versa, as the PS3 has some way to check that a person has used the wrong NPComm for a TRP.
But we do not know how it does this or what checks are done...
If we could find out how the PS3 knows what NPComm is supposed to match the TRP, maybe we can reverse it and generate the NPComm from having the game's TRP's?
That been said, I hope someone would be inclined to help us with this project. We have been talking with good Developers such as Flatz, we just want to sign someone who would like to join us... Maybe @aldostools?
I would gladly pay...
