Required Reading

YAMT (Yet Another Mount Tool) is a multi-purpose kernel plugin for the PS Vita (TV) which allows for the use of a microSD card as a storage device via an SD2Vita adapter. The SD2Vita is a microSD to game card adapter which is inserted into the game-card slot in your device.

By using the YAMT kernel plugin, the USB drive or microSD card you use will be mounted to ux0: just like a Sony memory card. This is very useful because microSD cards are significantly cheaper than Sony memory cards (especially at higher capacities).

This will use FTP (File Transfer Protocol) to transfer the files, so your Vita and PC must be connected to the same network.

If you’re using a USB drive or psvsd adapter, or if this method doesn’t work for you, follow the StorageMgr guide.

Samsung Evo cards are not compatible with YAMT. If you have a Samsung Evo MicroSD card please follow the StorageMgr guide.

YAMT is only compatible with firmware versions 3.60 and 3.65 on HENkaku Ensō.

If you want to reclaim the space on your memory card (to use for storing PSP games for instance), you can delete the contents of uma0: (the new memory card mount point) and / or imc0: (if you have a PS Vita 2000 or PS TV).

If you decide to do this, you must not delete these folders if they exist:

  • uma0:data/bootstrap.self
  • uma0:app/PCSG90096
  • uma0:appmeta/PCSG90096
  • uma0:appmeta/VITASHELL
  • uma0:license/app/PCSG90096
  • uma0:license/app/VITASHELL
  • uma0:user/00/savedata/PCSG90096
  • uma0:user/00/savedata/VITASHELL

This is because you must keep h-encore installed to the memory card so you can enable HENkaku (and therefore StorageMgr) after a reboot.
