Official SGS Edit: This map and scenario editor was created by Strategy Game Studio. Developers use it to create scenarios for the SGS series, such as SGS Winter War. The studio can share source files with modders who want to create their own modules, even though the final game files are not directly editable.

Manual .sgs File Editing: Many games use the .sgs extension for save data. In games like Starpoint Gemini Warlords, these are simple text files. They can be opened with a text editor like Notepad or Notepad++ to change player levels, perks, and credits. Key Features and Capabilities

Depending on the method used, the following can be achieved:

Scenario Modification: Use SGS Edit on Steam to create new game modules or modify existing data for SGS series titles.

Character Progression: Adjust experience points (XP), skill points, and perk points.

Resource Management: Edit values for in-game currency or specific crafting resources.

Difficulty Balancing: Modify game parameters to adjust the challenge level or fix a corrupted save file. How to Edit .sgs Save Files

For games where .sgs files are plain text, follow these steps:

Find the Save Folder: It is usually in your game's local storage or the Documents folder.

Create a Backup: Always copy the original save file before making changes to avoid data corruption.

Open with Text Editor: Right-click the .sgs file, select "Open With," and choose Notepad++ for better readability.

Find and Replace: Use Ctrl + F to search for terms like "Credits" or "Level" and update the numerical value.

Save and Load: Save the file and restart the game to see the changes. Safety and Risks

"Content" for an SGS save editor generally falls into two categories: official developer tools and manual text editing, depending on the game. 1. SGS Edit (Official Developer Tool)

For the official SGS series (by Strategy Game Studio), developers use a tool called SGS Edit.

Purpose: It is a map and scenario editor to create or modify game data, including units, terrain, and scenario elements.

Availability: The studio has stated they can share the source tool with modders who want to create their own modules or scenarios. The final game files are not directly editable.

Action: Contact the Strategy Game Studio directly to request access to create full mods or custom games. 2. Manual Editing (Starpoint Gemini Warlords)

For Starpoint Gemini Warlords, which uses the .sgs extension, a specialized program is not necessarily needed to edit save files. Format: These .sgs files are often plain text files.

Recommended Tool: You can open and edit them using any standard text editor. Notepad++ is highly recommended for its clear formatting. What you can edit: Resources: Change current money or level. Stats: Modify skill points or perk points.

Method: Right-click the file and select "Open With" -> "Notepad++". Use CTRL + F to search for keywords like "money" or "level" to find the values you want to change. 3. Underrail Save Modding

For the game Underrail, which features an "SGS" (South Gate Station) location, save editing is more complex:

Hex Editing: Players often use hex editors or specific "unpacking" tools to modify the global.dat file.

Cheat Engine: Many users prefer using Cheat Engine tables to edit inventory items and character experience while the game is running, rather than editing the save file directly. Safe Editing Tips:

Backup First: Always create a copy of the save file before making changes. A typo can cause the game to crash or fail to load the save.

Turn off Steam Cloud: If editing a Steam game, temporarily disable Cloud Sync so the game doesn't overwrite the modified file with the original.

Step 3: Make Your Modifications

Under Faction_0 > Resources, double-click Political Points. Change 45 to 5000.
Under Units, find your most battered infantry regiment (search by name or ID). Change Current_Strength from 34 to 100.
Under Regions, find the province code Helsinki. Change Supply_Level from 15 to 255.

🔧 SGS Save Editor – Feature Set

Backup Your Game

Corruption is rare, but always keep two unedited saves. If the editor crashes while writing, your save might be lost forever.

Error: Game Crashes on Load

Cause: You set an invalid value (e.g., Health to -1 or an Item ID that doesn't exist).
Fix: Restore your backup (you made a backup, right?) or use the editor to revert the specific value you changed.
