NMSE supports the 16 game languages. To change the display language:
- Click Language in the menu bar
- Select your preferred language from the list
The entire application - menus, labels, item names, and descriptions - will update to the selected language.
| Language | Code |
|---|---|
| English (UK) | en-GB |
| English (US) | en-US |
| French | fr-FR |

There are two ways to open a save file:
- Click Browse... or File > Open Save Directory in the menu bar
- NMSE will automatically detect your save file location
- A list of available save slots will appear
- Select the save slot and save file you want to edit
- Click Load
- Click File > Load Save File
- Browse to the save file on your computer
- Select the file and click Open
Use this method for PlayStation or Nintendo Switch saves that you've copied to your PC.
After making edits, save your changes using one of these methods:
- File > Save - Overwrites the original file (a backup is created automatically)
- File > Save As - Save to a new location without overwriting the original
⚠️ Important: While NMSE creates automatic backups, it's good practice to keep your own copy as well. Always keep a backup of your original save files before editing.
If something goes wrong, you can restore from a backup:
- Edit > Restore Backup (All) - Restore all save slots from backup
- Edit > Restore Backup (Single) - Restore just the current save slot
NMSE organises all editing features into tabs along the top of the window. Click any tab to switch to that section.

Current Coordinates shows your current location and details. You can manually edit and apply coordinates from the right hand column via the number fields, or via glyph buttons.
As an additional bit of fun, you can use the Coordinate Roulette! button to send yourself somewhere completely random (you will be prompted to confirm).
⚠️ Caution: Changing coordinates will move you to a different location in the galaxy. Make sure you know where you want to go!
You can copy, move slot, swap slot, delete and platform transfer a save from here.
⚠️ Caution: Ensure you have a backup of your save when using this utility! It performs complex operations for advanced users only.

Corvette ships are supported with some special considerations:
- Corvettes work jankily in the game save data
- Due to how corvettes work, you should summon your corvette and then set a new starship to primary before editing
- NMS saves only store the Technology slots in the starship keys for your last 'Recently Boarded Corvette'. If you intend to edit a corvettes inventories, you should always have this ship as your second last summoned ship for safety
- Corvette inventory slots are reverse looked up from the base data to show the correct technology slots. If you don't see them, you need to cycle the corvette per above
- NMSE has some safety prompts around these to help to guide you when editing corvette starships safely
Corvette type starships allow the following extra features:
- Snapshot / import a snapshot of the technology and ship status of a corvette, to reduce annoyance from the game jumbling the slots
- Optimise the build order of base components in the corvette design via the Optimise Build button. A Tick or Cross indicator shows the current optimisation status

For each plot (numbered 01 to 48), you can set the buildings status via the number entry field (or drop down list for known safe values).
An approximation of the building is noted below the plots fields.

This functionality is experimental and based on initial reverse engineering works.

|---|---|
| Building Editor | Edit an individual building/plots bitfields directly |
| Building Editor |
|---|
 |
Select the plot via the slot field. You can set the buildings status via the raw value number entry field.
The tick boxes below allow you to manipulate the bitflags in the bitfields within the composite integer. Each tickbox will manipulate the bits and produce the new integer to match.
This panel is for advanced users and requires either known useful values, or a solid understanding of the bitflags to net the most benefit.
This functionality is experimental and based on initial reverse engineering works.

| Platform Rewards | Platform-specific entitlements |
Each tab has the ability to unlock / lock all, unlock individually and filter the lists.
Platform rewards may require the user settings MXML file to also be edited directly depending on your platform. It will auto find the file on supported platforms, if not browse to GCUSERSETTINGSDATA.MXML in the NMS Binaries\SETTINGS\ directory
💡 Tips:
Due to how the game works, Twitch drops and platform rewards, you need to set your game to offline before starting the game to unlock the rewards.
You may also need to edit the platform rewards after launching the game (or lock the file from editing until after launch) due to how the game recreates the user settings MXML at runtime.
The Export Settings tab lets you set up export naming conventions and file preferences.
| Export Extensions | Export Templates |
|---|---|
 |
 |
Configure how exported files are named and what format they use. This is useful if you frequently export and share save data or maintain custom collections of your save data.
Use the help sub tab for variable references.
The Raw JSON Editor tab provides direct access to the underlying save file data in a tree view.
| Raw JSON Editor |
|---|
 |
The Raw JSON editor is for advanced users who need to edit values that aren't exposed in the other tabs. It shows the complete save file structure as a navigable tree view, text view, or a split view of both.
It supports basic syntax highlighting, node export/import and change diffing.
- Navigate the tree by expanding nodes
- Click on a value to edit it
- Modify the value in the edit field
- Press Enter to confirm the change
⚠️ Caution: Editing raw JSON values incorrectly can corrupt your save file. Only use this if you know what you're doing, and always keep a backup!
Use the Tree View, Text View or Split View buttons to switch betweeen the different view modes.
Use the Expand All and Collapse All buttons to fold/unfold all.
💡 Tip: The Expand All button will unfold up to half a million rows of keys and information depending on your saves age and density and can take a very significant amount of time to complete. It will warn you before you expand.
The Show Changes button can be used to show a basic diff (up to a maximum set of changes) for the save edits that have been made to the JSON objects.
Use the Search... field to search by string, key, etc.
You can also export/import per node object via the context menu by right-clicking the object/node.
For advanced edits, it is recommended to export the whole save JSON (or relevant node) and make changes in a capable external editor such as Sublime, VS Code, etc.
NMSE supports importing and exporting inventory data, making it easy to share loadouts with other players or make backups / inject into other items.
- Navigate to the inventory you want to export (Exosuit, Ship, etc.)
- Use the export function to save the inventory to a file
- Navigate to the target inventory
- Use the import function and select your file
- The items will be loaded into the inventory
NMSE can import inventories, multi-tools, ships, etc. from multiple save editor formats via key-matching, so you can share loadouts even if your friends use different tools.
Any keys that can be matched successfully will be imported.
NMSE auto-detects save locations for Steam, GOG, and Xbox Game Pass. If auto-detect doesn't work, save files are typically located at:
- Steam:
%APPDATA%\HelloGames\NMS\ - GOG:
%APPDATA%\HelloGames\NMS\ - Xbox Game Pass: Search for
NMSin the Xbox app data folder
Yes! You'll need to transfer the save file to your PC first via the homebrew of your choice (PS4: Apollo, SaveWizard, etc. - Switch: JKSV, etc.), edit it with NMSE, then transfer it back. Use File -> Load Save File to open manually transferred saves.
No Man's Sky does not have an anti-cheat system for save file editing. However, always use save editing responsibly and keep backups.
We do not support or condone cheating or editing at the expense of others. Please be responsible!
- Make sure you're using the latest version of NMSE
- Check that your save is from a supported game version
- Try restoring from a backup (Edit > Restore Backup)
- Ensure you haven't caused the issue externally with other tools or edits first
- If the issue persists, report a bug - ensuring that you give clear and thorough information
You can restore from the automatic backup that NMSE creates when you save. Use Edit > Restore Backup to go back to the last version before your edits.
