After downloading, use a tool like NSPVerify or 7-zip’s CRC SHA to check the file. A verified update should have a known checksum (ask in community discords for current hashes).

Assuming you have a homebrewed Switch (Atmosphere or SX OS) with signature patches installed:

  • Sigpatches: Ensure your hekate_ipl.ini has kip1patch=nosigchk enabled. Without this, the "verified" NSP will show as "Unable to start software."
  • Launch: Once installed, hold R while launching a standard title to enter Homebrew menu, then launch Okinawa Rush from your main menu.

    • ✅ Own a legitimate copy of Okinawa Rush
    ✅ Dump your own cartridge (using NXDumpTool) or download from scene archive
    ✅ Verify SHA‑256 against No-Intro or NSWDB
    ✅ Grab update v1.0.2 (check scene release logs)
    ✅ Install via DBI / Tinfoil on CFW Switch
    ✅ Confirm version in-game

    If you just need the latest official update file name for search purposes:
    Okinawa_Rush_Update_v1.0.2_NSW-HR.nsp
