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.
It requires a valid (official) PSP or PS1 license to work, a PSP DLC license should also work.
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.
User guide
Instructions can be found 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.
