MISSION FILE / SAVE-69

Save Files, Backups & Fields

Back up the entire user-data directory before changing anything. v1.00.61 exposes 69 main-save fields and 80 persistent fields across all schemas; this page reads documentation only and never uploads or edits your files.

REFERENCE STATEVERIFIED FOR v1.00.61CONFIRMED

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

6 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 v1.00.61 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	Global input mapping file; no longer tied to an individual save slot.
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().

v1.00.61 uses one global input-binding file. Bindings are no longer tied to an individual progress slot and are not reset when a save slot is reset.

GLOBAL INPUT CONFIG

Dynamic actions and serialized input events

Each action name maps to an event array. Keyboard keys, controller buttons and controller axes use the fields below when that event type applies.

Field pattern	Type	Purpose
`*`	array	Dynamic InputMap action name; value is an array of serialized events.
`*[].type`	string	InputEventKey, InputEventJoypadButton, or InputEventJoypadMotion.
`*[].physical_keycode`	integer	Present for keyboard events.
`*[].button_index`	integer	Present for joypad button events.
`*[].axis`	integer	Present for joypad motion events.
`*[].axis_value`	number	Present for joypad motion events.

03 / COMPLETION MODEL

How v1.00.61 calculates completion

The completion result is weighted and rounded; it is not a simple count of every stored field.

LEVEL FLAGS12

Each listed level-completion flag carries a weight of 3 before the game-beaten rule is applied.

DATA CHIPS8

All 160 chips contribute 8 weighted units—one unit per 20 chips.

FINAL VALUEROUND

The completed weighted total is divided by the available weighted total, multiplied by 100 and rounded to the nearest integer.

COMPLETION FORMULAround((completed weighted items + collected chips / 20) / available weighted items × 100)

When game_beaten is true, the 12 level flags are removed from the weighted calculation. The game_beaten field itself is also excluded.

INCLUDED

What raises completion

Group	Qty	Contribution
Level clears	12	3 units each until game_beaten
Boss weapon unlocks	8	1 unit each
Heart Tanks	8	1 unit each
Energy Tanks	4	1 unit each
System upgrades + Hadouken	9	1 unit each
Data Chips	160	1 unit per 20 chips

The stored chips total is marked as a raw inventory value because it is handled separately by the formula. It still contributes up to 8 weighted units. game_beaten changes the denominator but does not add a completion unit itself.

double_tap_dashDefault: falseExcluded from completion

Saved control preference; it does not inflate completion.

enable_weapon_wheelDefault: trueExcluded from completion

Saved control preference; it does not inflate completion.

global_lights_onDefault: trueExcluded from completion

New persisted global-lighting preference.

game_beatenDefault: falseExcluded from completion

New completion-state field used to refine the final percentage.

05 / 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.
