Finally... some Christmas cheer!

[spewfr]

That is... wonderful. You guys really have outdone yourselves. Congratulations to all you've done for this scene
Edit: I got TDU and Worms to work. Dunno about other games. Pilot Academy and other games did not work.

Had to push v1.0.4 since I missed a very important change in the last commit. The new EBOOT.BIN tags couldn't be selected since sign_np was still restricting them to only 11 tags.

Cool thanks Hykem .. I got lost replacing the kirk engine from fake_np with your libkirk.. it did something weird with sceDrmBBC and started failing on the NP Header MAC when running fake_np.

I meant use the full base like fake_np.. not just modifying/ecdsa NPUMDIMG header

I also noticed some games have different flags.. Gungnir and Space Invaders Extreme have NPUMDIMG flag 03 instead of 02 resigning these with version key just returns error when launching under TNV.

Ah yes, those games are for PSP right? PSP games normally use the 03 flag instead of the 02.

On a side note, if you have a blacklisted game installed, that won't work as base. The Vita will refuse to load anything that has it's content ID or version key.
Also, it's quite possible that some games can't be used properly as "base" due to the OPNSSMP module.
To test this, grab the base game's EBOOT.PBP and open it up in an hex editor. Search for a "PGD" string which will be the encrypted OPNSSMP module.
You can now copy the full PGD image (starts with the PGD magic and finishes right before some NULL padding) to a new binary file and decrypt it with pgdecrypt by tpunix.
It should give you a "~PSP" module that you can now include in your new image.
To do this just call sign_np as:

Code: Select all

sign_np -pbp NP.ISO EBOOT.PBP [CONTENT ID] [VERSION KEY] OPNSSMP.BIN

The module will be re-encrypted with the new version key and will be loaded by the pspemu.

Also, you can include your own custom boot screen by doing something similar:

Code: Select all

sign_np -pbp NP.ISO EBOOT.PBP [CONTENT ID] [VERSION KEY] STARTDAT.PNG

Or even include both OPNSSMP and boot screen files at once:

Code: Select all

sign_np -pbp NP.ISO EBOOT.PBP [CONTENT ID] [VERSION KEY] OPNSSMP.BIN  STARTDAT.PNG

I have a question Hykem. Would it be possible to include the version key as "version_key.bin" instead of its HEX value, like it is possible with the OPNSSMP.BIN (I assume)?

That would make things a lot easier.

Custom boot screen = Health warning screen / minis screen / et cetera? What size would that PNG be? 480x272?

they are psp games but run on the vita.

Yes, sorta like the PS1 boot screen for every PS1 game, or the PS3's Motion Warnings screen for games involving the move handset 480x272
is correct

Yea 480x272. here's one I pulled from Gungnir.

[Belmondo]

Ah yes, those games are for PSP right? PSP games normally use the 03 flag instead of the 02.

With Gungnir I pulled out the OPNSSMP.BIN and STARTDAT.PNG

sign_np.exe -pbp ACID.iso EBOOT2.PBP EP0005-NPEH00135_00-DPTHEAVENGUNGNIR 75F587CAA5DF75A75F07ED3B8E7F5C05 OPNSSMP.BIN STARTDAT.PNG

When running the game the STARTDAT appears and then 80010087 error when running under TNV..

The only thing i can think of that it could be is with the 03 from the original game.

Code: Select all

instead of the 02 which sign_np creates.

Sure, I'll add that on the next commit.
Yes, the custom boot screen is the warning screen (480x272), just like Belmondo posted.

Hmm, this is one of those special cases I've seen before.
The np_flags can be described as:

Code: Select all

01 00 00 00 -> License is bound to Memory Stick and uses Version Key
01 00 00 01 -> License is bound to Memory Stick and uses Fixed Key
02 00 00 00 -> License is bound to Network and uses Version Key
02 00 00 01 -> License is bound to Network and uses Fixed Key
03 00 00 00 -> License is bound to the file itself and uses Version Key
03 00 00 01 -> License is bound to the file itself and uses Fixed Key

The Memory Stick ones are never used (only present in the PSP's kernel code).
Normally the 03 flag, which binds the license to the file itself, uses the Fixed Key in the PSP, but I've seen a few games that use the Version Key instead.
I still need to figure out what is the meaning of this in the Vita itself, but it's very likely that those games don't work due to the flags indeed.

Yea, I got it. I found the douchiest picture I had from 5 years ago and used it. It worked :P

So when will the Z be releasing the tutorial on how to do this ..... ?
and where did you get the startdat.png i dont see it anywhere in any eboots i have of my psn games
