This tool allows you to make exact copies (1:1 backups) of your PSV Game Cartridges, including the CMD56 authentication data. Additionally, it can format, backup, and restore specific sections of game cartridges. The output is in the form of .vci files (vita cartridge image), which contain both CMD56 authentication data and the raw image of the game cartridge.

You can perform backups over the network, onto an official memory card, a USB device connected to a Vita TV, or using OTG on Vita 2k (requires an OTG cable with an external power source or Y-cable like this one). It's also compatible with the Accessory Port on Vita 1K or host0 on Development Kits.

The .VCI format differs from .PSV in how keys are stored, providing the theoretical possibility of creating a Vita flash cartridge. .VCI can also be converted to .PSV, but the reverse is not.
