I do as well. I cant figure out how to get PSP backups to work without it so I put Adrenaline on my Vita. I figured out how to get multiple types of Vita backups to run though.
Now Im just having trouble figuring out how to get plug-ins to work. I got one to work, RegistryEditor, and I use it to stop the screen from auto-dimming after 10 seconds of not touching a button. I cant get any others to work though. I tried to use Vita Plug-In Manager. It launches but im not sure where to put the plugin file(s) at.
