what is vita-save-keeper fr?

Save Keeper is a homebrew application for the PlayStation Vita handheld console that backs up your game save files and syncs them to your own Google Drive account. It is built for people who have modified their Vita with homebrew software, and it works with saves from Vita games, game cartridges, and PSP games run through the Vita's PSP compatibility layer. The app creates timestamped ZIP backups of your saves and can sign in to Google by having you scan a QR code with your phone, so you never have to type a password on the Vita's small on screen keyboard. Once connected, backups upload to a folder in your Google Drive, and because every device uses the same Google account, a backup made on one Vita can be downloaded and restored on another Vita or on a PS TV. You can back up and upload an entire tab of games at once, keep multiple backups per game so you can return to an older save, and label backups with names like before boss or 100 percent complete to tell them apart later. A few safety details stand out. Before restoring a backup overwrites your current save, Save Keeper automatically makes a backup of what you currently have, unless an identical one already exists, so an accidental restore never destroys progress. Since retail game saves are encrypted by the Vita's system software, the app uses a small kernel helper to read accurate save dates out of them, and falls back to approximate file times if that helper is not available. Setting it up requires a Vita or PS TV with HENkaku or h-encore homebrew enabled, the extended permissions setting turned on, VitaShell to install the app file, and about ten minutes to complete a one time Google Drive setup following the project's guide. The project can also be built from source using CMake, with a separate host build for running tests and a Vita build that requires the VitaSDK toolchain. It credits several third party libraries for QR code generation, JSON handling, and SQLite database access used to read the Vita's save catalog.
