Deja Vu is a newly released Vita homebrew that lets you make savestates
A new homebrew tool by the name of Deja Vu has just released. No, no, not that one, but rather an application for the PlayStation Vita. It may not be an exploit, but instead Deja Vu is a plug-in that acts as a savestate for your games. Just like you can in an emulator, you can now set a savestate and jump back to that point, which is useful in difficult games that don’t normally allow for saving at any time. At the time of initial public release, Deja Vu is still early in development, and is experimental. Creating a savestate takes about 60 seconds, while loading it takes a slightly shorter amount of time, with each savestate clocking in at around 400-500MB, meaning you’ll want to make sure you have the space to do so on your memory card. At version 0.1, it can also cause system crashes, so you’ll want to be careful.
If you do want to try this early build, you can go ahead and grab it from TheFlow’s GitHub.
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.
