MISSION FILE / SAVE-67

Save Files, Backups & Fields

Back up the entire user-data directory before changing anything. v1.00.4 exposes 67 main-save fields and 78 persistent fields across all schemas; this page reads documentation only and never uploads or edits your files.

REFERENCE STATEDATA v1.00.4CONFIRMED

BACKUP FIRST

Copy the directory, not just one slot

Keep a dated copy somewhere outside the live folder. Main progress, achievements, input settings and speed-run time use separate files.

01 / USER PATHS

Save-data directories

Godot's user:// location depends on the platform. These community paths remain labeled until device-tested.

02 / FILE MAP

Eight code-level save targets

The extension alone does not tell you the storage format.

.JSON ≠ JSON TEXT

Main slots and achievements end in .json, but v1.00.4 writes them with Godot's binary store_var() format. Opening them in a text editor will not produce normal JSON.

Target	Filename	Schema	Format	Note
main slot 1	`MMXSaveSlot1.json`	main save	Godot variant binary	Despite the .json extension, save() uses FileAccess.store_var().
main slot 2	`MMXSaveSlot2.json`	main save	Godot variant binary	Despite the .json extension, save() uses FileAccess.store_var().
main slot 3	`MMXSaveSlot3.json`	main save	Godot variant binary	Despite the .json extension, save() uses FileAccess.store_var().
input slot 1	`MMXInputSettingsSlot1.json`	input settings	JSON text	InputMap action-to-event dictionary.
input slot 2	`MMXInputSettingsSlot1.json`	input settings	JSON text	Current 1.00.4 code points slot 2 to the slot 1 filename.
input slot 3	`MMXInputSettingsSlot1.json`	input settings	JSON text	Current 1.00.4 code points slot 3 to the slot 1 filename.
speed run	`MMXSpeedRunTime.json`	speed run	JSON text	Contains best_speed.
achievements	`MMXAchievements.json`	achievements	Godot variant binary	Despite the .json extension, achievement state uses FileAccess.store_var().

Verified code quirk: input-setting slots 2 and 3 currently point to the slot 1 filename, so all three constants resolve to the same file in v1.00.4.

04 / RECOVERY BOUNDARY

Documentation is not an automatic repair tool

A current community report describes progression corruption when a boss and X die at the same time. The field dictionary can help identify what the game stores, but it cannot guarantee that editing a binary save will recover it. Restore a backup whenever possible.
