1) The very first thing to do now is to simply rename the 'PBOOT.PBP' file to '#0' without any file-ending!

2) Now we are going to write a new e-mail with the #0-file as attachment and the path we want the file to be installed to as Subject.

ux0:pspemu/PSP/GAME/GameID/PBOOT.PBP

(If you happen to not know your GameID, either use google or make a backup of the game and check the foldername!)

3) Send the e-mail to the mail-account registered on your Vita!

4) If everything did go right you should see a camera symbol. Touch it and DO NOT click OK on the appearing Error Message but simply close the e-mail app completely!

5) All you need to do now is to either rebuild the database or transfer your game to the PC and back to make the PBOOT.PBP take effect.

(You can access the Recovery Menu by powering off your Vita completely and press and hold HOME + POWER + R-TRIGGER)

Note: Rebuilding your database will make any other app.db depending hacks and tricks disappear. The PC method might be the better choice here!

1) Make a backup of the PSP game that you want to use as basegame for TN-V via CMA.

2) Find out your AID (PSN Accound ID). You can simply find it inside CMA's file structure once you backed up your game.

PSVita/PGAME/xxxxxxxxxxxxxxxx/NPXY00000/

3) Now visit http://cma.henkaku.xyz/, enter your AID there and copy the generated key.

4) Next up you'll need to download PSVIMGtools for your OS and extract it somewhere.

5) Copy the game.psvimg backup file from your CMA folder next to the just extracted psvimgtools.

6) Run the following code via terminal.

7) Inside your output directory you can now add the TN-V PBOOT.PBP file

8) Half way done! Next up run the following code via terminal to repack the backup file.

9) Copy back both created files in your output directory back to your CMA folder

PSVita/PGAME/xxxxxxxxxxxxxxxx/NPXY00000/game/

10) Update the QCMA Database or simply restart CMA to find the changed files.

11) And finally restore the backup back to your Vita
