You're referring to the Sound Voltex Ultimate Mobile update!

If you give me more details (where you saw the name, what device you're on), I can give you a precise, up-to-date answer.

  • Are you looking for the latest version number of an unofficial SDVX mobile app?
  • Or are you asking if KONAMI released an official update to a mobile SDVX game?
  • Or did you mean "Sound Voltex Ultimate Mobile" as in a custom skin for USC (Unnamed SDVX Clone) on Android?

Unlike other simulators like KShoot or Unnamed SDVX Clone, this mobile app focuses specifically on a vertical scrolling interface adapted for thumbs and fingers. It allows users to load their own song files (.ksh or .sdvx) and play official charts using custom skins.
