The Switch piracy and CFW scene is rampant with bad dumps. For Zombie Army Trilogy, watch for these red flags: Key Changes in the 1

  • Filename includes "v0" or "DEMO": Some groups uploaded a kiosk demo NSP as an update.
  • File size mismatch: The real v1.1.0 update is 458,395,648 bytes (exact). If your file is 500MB+, it might be the base game mislabeled.
  • Title ID Mismatch: The correct Title ID for the US version is 0100F8C00C8B2000. The update must share the same Title ID. If you install an EU update (Title ID ending in 800) on a US base, your Switch will create a duplicate, useless icon.
