Error 3: The install fails at 99% (NCA signature verification failed)

• Cause: Outdated sigpatches.
• Solution: This is extremely common. Update your sigpatches. If you are on Atmosphere 1.5+, you need patches for firmware 16.0.0+. Reboot into CFW after updating patches, then try again.

Post-install checks

• Confirm the game’s version number in its options or title info matches Update 1.
• Load several songs and charts to ensure no crashes or regressions.
• Verify any specific fixes listed in the update notes (e.g., timing adjustments).
• If issues occur, restore your save from backup and consider reinstalling the base title or the update.

• [ ] CFW is booted (Atmosphere, not Stock).
• [ ] Sigpatches are for the exact firmware and Atmosphere version you are running.
• [ ] The NSP update file matches the Base Game's Region (Check Title ID: 0100EB90120B6000 for US, 01005D100E2C2000 for JP).
• [ ] You have at least 2GB of free space on your SD card (for temp files).
• [ ] You have DBI or Tinfoil ready—Goldleaf is the backup, not the primary.
