hi everybody this is a little tutorial to know how to sign most of your psp backups
i just gonna show how to sign your backup, if you want use it on live area just search for the mrgas/tomtom bubble trick
i gonna use talkman travel tokyo information for the tutorial

what we need?
our base game.pbp that game will be installed on you vita (dont care if that game has a small size like talkman travel tokyo)
npdpc.exe here
hexeditor
sign_np here
PSfiler
your psp backup iso format (some games dont work on the live area so fell free to tell us what game can and cant work on live are)

this is our command line
sign_np -pbp <-c> <input.iso> <output.pbp> <CID> <Versionkey>
sign_np -pbp = encrypt and sign a psp iso into a PSN eboot.pbp
-c = compress your eboot.pbp (not every games work if they are compressed)
input.iso = your psp iso to sign
output.pbp = EBOOT.PBP signed (result of your iso game)
CID = content ID of your base game
versionkey = your key to sign a psp iso game

how to get your CID
you got 2 way to get it
way #1 if you have installed your base game (i wanna think you have installed) just open a PSfiler and go to /PSP/LICENSE/ the name of the .rif file for your base game its your contentID
way #2 go to store.sonyentertainmentnetwork.com/ and search for your base game and into navigation bar search for cid=xxxxxx-xxxxxxxxx_xx-xxxxxxxxxxxx example with talkman travel tokyo https://store.sonyentertainmentnetwork. ... NTOKYO0000 where UP9000-NPUG80155_00-TALKMANTOKYO0000 its the CID

how to get your version key

1.- put everything in a folder for a clean work 2.- rename you base game.pbp to np.pbp and run npdpc.exe you gonna get a file named version_key.bin 3.- open the version_key.bin with hexeditor 4.- copy the hexadecimal values without space and that its your versionkey example B7F53FEE7D45E449FEA72EA03A464EA4

now we have everything to sign our psp iso games
open your CMD into the folder where you have the files sign_np, and your iso psp
and write the comand line with your info

example sign_np -pbp -c crisis-core.iso Eboot.pbp UP9000-NPUG80155_00-TALKMANTOKYO0000 B7F53FEE7D45E449FEA72EA03A464EA4
sign_np -pbp -c input.iso output.pbp contentID Versionkey

if you dont want write everytime that line open a text file and write the line
"sing_np -pbp game.iso eboot.pbp yourCID yourKEY"
example talkman sign_np -pbp game.iso eboot.pbp UP9000-NPUG80155_00-TALKMANTOKYO0000 B7F53FEE7D45E449FEA72EA03A464EA4
and save as sign.bat in the same folder you have sign_np
now to sign you only need rename your iso to game.iso and placed in the same folder and double click to sign.bat

if this just kicked back to the live area try sign the eboot.bin first

if you want sign the eboot.bin just
1.- extract the eboot.bin in the same folder and use this command line
sign_np -elf <youreboot.bin> <result.bin> 2
2.- delete the eboot.bin (original one)
3.- the result .bin file rename it to EBOOT.BIN
4.- repack your ISO game with the new eboot.bin

if there is something to hide please tell me
thanks to hykem

the game to sign is on iso if you want to compress the eboot.pbp its your choice but some games dont work if you compress it

Good day... Have someone tried to sign the FF Type 0 English patch and used it on the Live Area?

Yes, and it takes you back to the Live Area. Of course their are different base games that won't work with every game.

Has anyone had any luck getting Persona 3 Portable to work with this on psp OFW and vita at all?

Tried it on psp OFW and it just kicks me back to XMB and throws error 80020148 at me.

Well pretty much every iso backup I've tried results in that except for Angry Birds, but that was an official psn pkg converted to iso so i dunno if that makes any difference. Well i guess it might seeing as it's the only one that's worked so far.

Haven't even bothered trying on vita as i figure if it doesn't work on psp it probably won't on vita either.

Tried a few different base games of different sizes (not sure if it matters at all or not) with the same end result.

Excellent Post.

I will deffo be giving this a go and seeing if I can finally make my TYPE0 bubble.

Is there any known limitations? Or is it still the same limitations that the bubble hack has (I.e mini's are hit and miss for example)

THIS DEFINITELY WORKS I HAVE MADE 3 bubbles using uno as a base for a game that is much larger then uno THANK YOU SO MUCH SAVES ALOT OF SPACE

i dont know, i dont have a mini to test but i think its the same limitation,

There is no limit on iso size with this procedure it's mainly hit or miss . Will the game boot from the live area . I cannot get dbz tenkaichi tag to boot at all imma try a different base
