déjàvu: Vita SaveState Plugin
déjàvu is a plugin for the PlayStation Vita that allows you to make a snapshot of the RAM at any point and later restore it. It allows you save in games where it is officially not possible. A potential use case for developers is to temporarily downgrade/update the firmware (in RAM) in order test things (this has not been tested yet).

Requirements
A Memory Card is required for this plugin.

Installation
Download dejavu.skprx and copy it to ux0:tai/dejavu.skprx.

Edit ux0:tai/config.txt and add its path to *KERNEL as follows:

*KERNEL
ux0:tai/dejavu.skprx
Reboot your device and enjoy this new feature.
