Introduction

NomNom is a savegame editor for No Man's Sky, but also shows you additional information around the data you are about to change. You can also easily look up each item individually to examine its attributes, independently of a savegame, or get other useful information that are not related to a specific one (but enhanced if one is loaded).

You will most certainly notice a similarity to the editor by goatfungus but when this project started it was the only one working and the general layout was good, so why reinventing the wheel? But there are features missing I would like to have and (in my eyes) bad usability in some areas. I also wanted to have a place where I can directly see how good my stats are, without searching through an online wiki or such. Therefore I started my own project for fun and here we are.

Features

The features of NomNom can be divided into the different main parts you will see below. A detailed list can be found in the FEATURES file.

• Manager Manage your saves!
  • Automatic backup and recovery (in case you screw something up).
  • Save your save as human-readable JSON.
  • Copy, move, and swap slots to another.
  • Transfer your save to another platform you own the game on.
  • Delete your save.
• Editor Edit your save for your needs!
  • Ability to edit cross-save rewards from Expeditions, Twitch Drops, Titles and more.
  • Ability to manage fleets, change data values like currencies and stats, and organize inventories.
  • Ability to fast travel to any system you like and trigger space battles.
  • Ability to customize appearances.
  • Ability to edit your knowledge and recorded experiences.
  • Ability to edit the raw JSON (for advanced users).

The images are from version 4.00.0.31-beta.1. More and maybe newer can be found here.

Getting Started

Compatibility

The latest version of NomNom is built with Omega 4.50 in mind. Previous versions are compatible with Beyond 2.11 and up. If you use it with a game version branch above (e.g. 5.00), things should work as usual in most cases but there can always be a breaking change.

Each version is properly supported with its own set of available items and features.

Each platform has anchor file patterns to check whether it is worth to look further into the selected directory. This must be in or one level below the selected one.

• GOG.com (Windows PC)
  • Location: %AppData%\HelloGames\NMS\DefaultUser
  • File Patterns: save*.hg
• PlayStation 4
  • File Patterns: memory.dat, savedata*.hg
  • Notes: There are a few options to do this. The only one that does not require homebrew is SaveWizard. Two other tools that are confirmed working are Save Mounter and Apollo but require homebrew. Results of other tools may or may not work but the code is as generic as possible.
• PlayStation 5
  • Notes: This version of the game is not supported due to restrictions on the console itself. By playing the PlayStation 4 version on it, you can still save edit with a few additional steps.
• Steam (PC)
  • Location
    • Windows: %AppData%\HelloGames\NMS\st_<SteamID>
    • SteamDeck: ~/.local/share/Steam/steamapps/compatdata/275850/pfx/drive_c/users/steamuser/Application Data/HelloGames/NMS/st_<SteamID>
    • macOS: ~/Library/Application Support/HelloGames/NMS/st_<SteamID>
  • File Patterns: save*.hg
• Microsoft Store (Windows PC)
  • Location: %LocalAppData%\Packages\HelloGames.NoMansSky_bs190hzg1sesy\SystemAppData\wgs\<XboxID>_29070100B936489ABCE8B9AF3980429C
  • File Patterns: containers.index
  • Notes: Reloading of modified saves while the game is running does not work.
• Nintendo Switch
  • File Patterns: manifest*.dat
  • Notes: To get your saves you need homebrew software on your Switch. EdiZon and JKSV are confirmed working. Results of other tools may or may not work but the code is as generic as possible.
• Xbox One/Series X|S
  • Notes: Not directly supported but can easily achieved with cloud sync via the Microsoft Store. The synchronization is triggered short after you close the game (no need to load a save).

Requirements

You just need to install the .NET 6 Desktop Runtime and that is it.

Download

• GitHub (NomNom.zip)
• Nexus Mods

Instructions

GUI

1. After downloading and extracting the zip file you'll find a few files. All you need to care about is the executable (NomNom.exe) but new folders may be created at runtime (e.g. for backups) that will become relevant to you.
2. You may want to create a shortcut to the executable for easier access.
3. As the tool includes an automatic backup functionality you don't need to do it manually but if you want to be absolutely save, do it.
4. At first start the tools locates your saves at the default location of each platform but if that fails, you have to select it manually.
5. Select a slot.
6. Start tinkering!
7. Guide and Catalogue will work without loading a save.

Versioning

The versioning is oriented on the game version itself:

• Major mirrors the games major version.
• Minor mirrors the games initial minor version of named updates (e.g. Synthesis 2.20 or Outlaws 3.85).
• Patch includes new features, bug fixes, updated game assets, and such beside the named game updates.
• Revision serves as public release counter.

Changelog

The complete history can be found in the CHANGELOG file.

There is also a ROADMAP file with things planned for the future. It's not set in stone but you will get an idea what is coming next.
