    Advanced Mode Guide

    Advanced Mode is the escape hatch for values that do not yet have a safe, player-friendly action. It exposes the decoded save while keeping search, validation, and backup steps close by.

    Quick Edit vs Popular Actions vs Advanced Mode

    Quick Edit

    Use it for established resource fields such as Rosaries and Shell Shards.

    Popular Actions

    Use save-aware checkers and narrowly verified recovery actions.

    Advanced Mode

    Use it when you know the field or item name and accept the added risk.

    How to search

    1. Upload the original userX.dat and download an original backup.
    2. Open Advanced Mode after the Popular Actions cards.
    3. Search an item name, field name, or visible value. Search is case-insensitive.
    4. Use Previous and Next to move through highlighted matches.
    5. Read the surrounding object before changing anything.

    Common data types

    Boolean
    true or false, often used for an unlocked or completed state.
    Number
    A count, mode, level, or progress value. The valid range depends on the field.
    String
    Text such as an item Name or game version.
    Object / array
    Grouped values. Do not delete brackets, commas, or neighboring entries.

    Verified example: Rosaries

    Quick Edit writes Rosaries to playerData.geo. In Advanced Mode, searching geo locates the same numeric field. Change only the number and keep the JSON punctuation intact.

    "geo": 250

    If an edit goes wrong

    Close the game, restore the original backup, and test it before making a second edit. Do not keep stacking guesses onto an already modified file.
