MH4U Save Editor is a savegame editor for Monster Hunter 4 Ultimate on the 3DS. It also handles the decryption or encryption processes automatically.

Features

  • Item box editor.
  • Equipment box editor.

User guide

Backup your save with Checkpoint or SaveDataFiler. You will end up with a system-file and either, some or all of user1, user2, user3 files depending on your characters.

Copy a userX-file to the PC (best use ftpd, so you don't need to remove the card) (It's also better to copy the whole save-folder with all files and rename it, so you have a backup in case something goes wrong).

Open the userX-file in editor, edit something and hit save. The file will be overwritten.

Move the userX-file (or save-folder) back to the 3ds and import with Checkpoint / SaveDataFiler.

Note: If you move/copy one file to a different folder on your 3ds, make sure that you also copy the other files to the same location otherwise you might loose characters or settings.

Notes

  • It is advise to only edit existing quests for now. If a quest already has a second monster, you can modify it, but don't add a second monster to it.
  • Do not enable relic-specific fields on non-relic armor (depending on the item's it, it may result in invalid item and the game will delete it on next launch).
  • For weapon, only relic weapons (end-game IDs) have full editing options. Non-relic weapons show limited options to prevent invalid items.
