Chovy-sign is an application that allows you to convert PSP and PS1 ISOs to be playable on unmodified PSVitas. This tool was developed by a few different people, such as KuromeSan and RupertAvery, who contributed to the creation of the tool and its various components. The tool requires a valid (official) PSP or PS1 license to work, and it is recommended to use specific games such as Petz Saddle Club, LocoRoco Midnight Carnival, or Ape Quest Starter Pack.
Chovy-Sign is an application that allows you to convert PSP and PS1 ISO's to be playable on unmodified PS Vita. The release was part of Project Chovy and was primarily created to allow PSP emulation on the PS Vita.


Chovy-sign was primarily created to allow PSP emulation on the PS Vita. The latest PS Vita firmware, which is 3.71, has rendered all previous hacking techniques useless, and unless you’re on a previous firmware version, you can’t play the PSP titles themselves. The authors of the tool have publicly stated that they don’t support piracy in any way, and you should only use it if you have officially purchased the titles or own UMDs.
It requires a valid (official) PSP or PS1 license to work, a PSP DLC license should also work.  


==How To Use==
This tool is intended for making back up of the games that you actually own. The authors do not promote or condone piracy in any way.
There are two ways to use chovy-sign: if you have a hacked PSVita or if you don't. If you don't have a hacked PSVita, you'll need to copy the game to your PC using Content Manager and then open chovy-sign2 and click the ""Get Keys"" button. You'll then need to select the ""EBOOT.PBP"" method and click on the game. After that, the RIF and KEY fields should populate, and you are good to go. If you have a hacked PSVita, you can still use the unhacked Vita method if you would like, but Content Manager is not the fastest way to transfer files.
 
==User guide==
Instructions can be found [https://silica.codes/SilicaAndPina/chovy-sign/src/branch/master/README.md here].
 
'''Notes:''' ISOs made with Chovy-Sign are "clones" of the original "base game", if you delete any of them it deletes the license.rif which breaks all the other "clones". This can be fixed by re-downloading the base game off of the PSN or copying any "clone" over to your PS Vita again.

==Compatibility==
 
Works on FW 3.71 (CFW and OFW).
==Notes==
One notable aspect of chovy-sign is that it uses a custom implementation of [[Psvimgtools Vita|PSVIMGTOOLS]], which runs faster and is more accurate to the .psvimg format. Furthermore, chovy-sign now shows a progress bar while signing the declaration of independence and has fixed a bug where your CMA directory wouldn't be found automatically.
 
It is important to note that deleting the PSP demo used for chovy-sign would give you errors when opening the PSP games you put on the Vita. This issue predates chovy-sign and even henkaku and has to do with the PSP bubble cloning trick. It has been around since 2014, and there isn't really anything you can do to prevent it. Games made with this are ""clones"" of the original ""base game,"" so if you delete any of them, it actually deletes the license.rif, which breaks all the other ""clones"".
