Why "Update 1.2" is Non-Negotiable

When you search for "pokemon ultra sun update 12", you are looking for Version 1.2. This is the final patch released by Nintendo for Ultra Sun & Ultra Moon. Unlike minor bug fixes, Version 1.2 is mandatory for several reasons:

  1. Online Functionality: If you intend to trade or battle online via pretendo (or the now-defunct official servers), the game forces you to run v1.2.
  2. The Zygarde Cube Fix: Early versions of the game had a save-corrupting bug involving the Zygarde Cube. v1.2 patches this entirely.
  3. New Event Distribution: The rarest events (like the shiny Poipole or Zeraora) require v1.2 to be recognized by the game’s internal event flags.
  4. Stability: Frame rate drops in double battles (especially on original 3DS hardware) are noticeably improved.
