Regular updates are released to add more features to the units. Custom software's are also released for special client requirements. The software up-gradation process can be easily performed on site by following the instructions below:


INFORMATION: The latest software updates are available from your my Workshop portal.

Information: It is advisable to make a backup of your settings before upgrading your software.


WARNING: Check that while copying file from email the file name is not renamed and is exactly "00000660.HTG"


The example below is for controller with serial number 5A-660


  • Check that the file name matches the serial number of the controller.
  • Connect a USB flash drive to your PC/MAC and make sure it's been formatted in FAT or FAT32 format.
  • Ensure that your flash drive is using MBR as GPT is not supported.
  • Extract the files from the Zip file downloaded from myWorkshop "00000660.HTG" and Data1.HTG files and copy them to the root directory of your USB flash drive.
  • Plug the Flash drive into the port labeled with a picture of a Flash Drive
  • NOTE: Make sure that there is nothing connected on the PlayStation connector on the MASSO
  • Insert the USB flash drive into the controller's USB flash drive connector and DO NOT connect a USB hub.
  • Power up the controller and a progress bar will be displayed on the screen showing the upgrade status.
  • Once the progress bar shows 100%, the upgrade process is finished, please power cycle the unit.
  • Do not remove the flash drive from MASSO as the Data1.htg file is loaded after the first power cycle.
