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
