6. Preservation & Legal Status

Copyright holder: Capcom Co., Ltd.
Legal status: Unauthorized distribution of CIA files infringes copyright. This report is provided for educational and archival research only, consistent with legitimate console homebrew and preservation efforts where local laws permit backups of user-owned software.
Archival note: This update is necessary for full event quest access. Without it, certain DLC quests and online features are unavailable.

4.1 How the Update CIA Works on 3DS

Installation – Via FBI, GodMode9, or other CIA installer on a CFW 3DS.
Overwrite Mechanism – The update writes to the NAND’s 0004000E title folder, leaving the base game (00040000) untouched.
Boot Priority – The 3DS firmware loads the higher version number from the update partition first.
Save Compatibility – Post-update saves are not backward compatible with the unpatched game.

Error: “Update installed, but version still shows 1.0”

Cause: You installed the update CIA before you inserted the cartridge or before the base game ticket was registered.
Solution: Launch the base game once (close it), then re-run the FBI installer. The 3DS needs to create the base seed file first.

5.1 Legitimate Use (Preservation & CFW)

Digital Preservation – Archiving the final state of a region-locked game before eShop closure (March 2023).
CFW Enhancement – Playing on a region-changed or out-of-region 3DS (e.g., playing JPN MH4G on a US console).
Performance – Some updates improved framerate in crowded online hubs (e.g., Val Habar).

Error: “Failed to install CIA – Cert signature or hash mismatch”

Cause: The CIA file is corrupted, a dummy file, or downloaded from an untrusted source.
Solution: Re-download from a reputable 3DS ROM archive and verify the MD5 hash.
