YAMT (SD2Vita)

For support in English, ask for help at HENkaku on Discord.

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).


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


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

What You Need

  • A storage device compatible with your system
    • This can be a microSD card to use in an SD2Vita or psvsd adapter, or a USB device for a PS TV console
  • The latest release of VitaDeployOpen in new window


Section I - Formatting the microSD


If you previously installed StorageMgr or another storage plugin, please remove it from your ux0:tai/ or ur0:tai/ folder before continuing.

  1. Insert your SD2Vita with the microSD card into your PS Vita or PS TV device
  2. Launch the VitaDeploy application
  3. Press × on Miscellaneous
  4. Press × on Format a storage device
  5. Ensure Target is set to "SD2Vita" and Filesystem is set to "TexFAT"
  6. Press × on "Format target storage"
    • If this fails, ensure the adapter is inserted properly and is undamaged - then reboot and try again
    • If it still fails, follow the StorageMgr guide
  7. Navigate back to the Vita Deploy menu and press × on "Reboot your device"

Section II - Installing yamt-vita


If you did the 3.65 Quick Install of VitaDeploy, you already have YAMT installed and can skip this section.

  1. On your device, open VitaDeploy
  2. Press × on App Downloader
  3. Select × YAMT Installer
  4. Press × on Download the selected apps
  5. Press × on YAMT.vpk and confirm with × again to install
  6. Once done Close out of the VitaDeploy application
  7. Launch the newly installed YAMT Installer application
  8. Press × on -> Install the lite version
    • Once finished, your device will reboot

Section III - Enabling the YAMT driver

  1. Open the Settings application
  2. Navigate to Devices -> Storage Devices
  3. Enable "Use YAMT" to enable the YAMT driver
  4. Set ux0: to "Default"
  5. Set uma0: to "SD2Vita"
  6. Hold the power button and select "Power Off"

Section IV - Transferring Data


This section will copy the data from your old Sony memory card (or internal storage if you don't have a Sony memory card) to your new storage device. It is recommended to not skip this section, so that the switch from the old main storage to the SD2Vita is as seamless as possible and all your apps carry over.


If you are coming from the Using Henlo guide, you may need to install VitaShell using VitaDeploy.

  1. Power on your device to reboot
  2. Open the VitaShell application
  3. Navigate to the ux0: partition
    • This is currently your official memory card or internal storage
  4. Press down on the D-Pad to highlight a folder or file
  5. Press to bring up the menu
  6. Press × on "Mark all" to select all folders and files in the ux0: partition
  7. Press again to bring up the menu
  8. Press × on "Copy"
  9. Press × again when prompted
  10. Navigate out of the ux0: partition and enter the uma0: partition
    • This is your unofficial storage device's memory
  11. Press to bring up the menu
  12. Press × on paste and wait for it to finish
  13. Once done, exit VitaShell and open the Settings application
  14. Navigate to Devices -> Storage Devices
  15. Set ux0: to "SD2Vita"
  16. Set uma0: to "Memory Card"
    • If you're not using a physical memory card in the memory card slot, select "Internal Storage"
  17. Hold the power button and select "Power Off"
  18. Power on your device to reboot

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:app/PCSG90096
  • uma0:app/VITASHELL
  • uma0:appmeta/PCSG90096
  • uma0:appmeta/VITASHELL
  • uma0:data/bootstrap.self
  • 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 YAMT) after a reboot.
