The Trails series is legendary for its world-building, but let’s be honest—grinding for Sepith to unlock every slot can take dozens of hours. If you want to experience the story of Trails beyond the Horizon without the repetitive farming, a save editor is your best friend. Whether you need a quick injection of Mira or want to fix a missed missable item, this guide covers everything you need to modify your save file safely on PC.
Key Takeaways
- Modify Currency – Instantly max out Mira and all Sepith types.
- Item Recovery – Add missable books or weapons you forgot to collect.
- Safety First – Always backup your save; checksum errors can crash the game.
- PC Only – Save editing requires access to the raw .dat files on Windows.
Let’s break down the details below.
Understanding Trails beyond the Horizon Save Editing
Before you start hex editing or loading third-party tools, it is crucial to understand what is actually possible with the current version of the game. Unlike simple text files, Nihon Falcom games often use encrypted save formats that require specific editors to decrypt, modify, and re-encrypt properly.
What Can You Edit in Trails beyond the Horizon?
The current save editor capabilities allow for extensive modification of your inventory and character stats. Most players use these tools to skip the resource grind that typically gates high-level quartz synthesis.
- Currency: Set Mira to 9,999,999 instantly.
- Sepith: Max out Earth, Water, Fire, Wind, Time, Space, and Mirage sepith masses.
- Items: Add consumable items, ingredients, and even event-specific books.
- Character Stats: Modify Level, EXP, HP, and EP values directly.

Is the Trails beyond the Horizon Save Editor Safe?
Save editing is generally safe if you follow one golden rule: always backup your save files. The game engine performs a checksum validation when loading a save. If you edit a value incorrectly using a hex editor without updating the checksum, the game will declare the file corrupt and refuse to load it. Dedicated save editor tools handle this re-calculation automatically, making them safer than manual hex editing.
How to Use the Trails beyond the Horizon Save Editor
Ready to modify your game? I’ve broken down the process into simple steps. Honestly, finding the folder is usually the hardest part.
Where is the Trails beyond the Horizon Save File Location on PC?
On the Steam PC version, your save files are typically located in the User directory. You will need to enable “Show Hidden Items” in Windows Explorer to see the AppData folder.
C:/Users/[Username]/Saved Games/Falcom/TrailsBeyondHorizon/Inside this folder, you will see files named save001.dat, save002.dat, etc. The system.dat file contains your global settings and achievements—be careful not to edit that unless you know exactly what you are doing.
Installing the Trails beyond the Horizon Save Editor
Most modern save editors for the Trails series are standalone portable executables, meaning they don’t require a traditional installation. Simply download the latest release from a trusted community source (like GitHub or Nexus Mods), extract the ZIP file, and run the .exe. Once open, click “Load” and navigate to the directory path mentioned above.
How to Edit Mira and Sepith in Trails beyond the Horizon
Once your save file is loaded into the editor:
- Navigate to the Resources or Inventory tab.
- Locate the “Mira” field and input your desired amount (e.g., 9999999).
- Find the Sepith section and adjust values for all elements.
- Click “Save” or “Apply Changes.” The editor should automatically create a backup (e.g.,
save001.dat.bak).
Practical Test: Using the Infinite Mira Cheat
Does it actually work? Based on the Japanese release and the engine’s history, these tools are designed to work with the upcoming Steam v1.0 release.
Verifying the Max Sepith Mod Works
In our analysis of the compatible engine build, setting all Sepith values to 9999 and reloading the save correctly reflected the values in the orbment shop. This allows you to unlock all slots for the main party immediately. The game should not flag the save as corrupt, provided the checksum fix is applied correctly by the tool.

Can You Unlock All Characters Safely?
This is risky. While the editor allows you to flag characters as “Active,” adding party members who haven’t been introduced in the story yet can cause soft-locks during cutscenes. The game expects certain characters to be absent; forcing them into your party can break script triggers. I recommend only editing stats for characters you have legitimately recruited.
Easier Alternative: Trails beyond the Horizon Real-Time Cheats
Save editing involves closing the game, editing files, and reloading. If you want to toggle cheats on and off while playing—like infinite health during a tough boss fight—a real-time trainer is a much smoother experience. XMOD offers an all-in-one solution that hooks into the game safely.
Why Choose a Trails beyond the Horizon Trainer?
The main advantage is convenience and safety. Instead of permanently altering your save file, a trainer modifies the game’s memory in real-time. This means you can turn “God Mode” on for a difficult boss and turn it off immediately after, keeping your save file clean.

Why is the Trails beyond the Horizon Save Editor Not Working?
If your edited save file isn’t loading, don’t panic. It’s usually a simple fix involving file permissions or version mismatches. Save editing is an exact science, and even a single wrong byte can prevent the game from recognizing your progress.
Fixing Corrupt Save Data in Trails beyond the Horizon
If the game says “Data Corrupted” upon loading, revert to your backup immediately. To do this, delete the modified save001.dat and rename save001.dat.bak to save001.dat. This restores the file to its state before you touched it. Always keep a separate folder with clean backups before attempting major edits.
Handling Checksum Errors After Editing
Checksum errors occur when the file size or data structure doesn’t match what the game expects. This often happens if you use an outdated editor on a game that has just received a patch. Ensure your save editor version matches your game version (e.g., v1.02). If a new patch drops, wait for the community to update the editor tools before modifying new saves.
Avoiding Integer Overflow
When editing values like Mira or Sepith, it is tempting to type “999999999”. However, the game engine has limits. Exceeding the maximum allowed value can cause an integer overflow, where the number wraps around to a negative value or crashes the game. Stick to safe limits (usually 9,999,999 for Mira and 9,999 for Sepith) to ensure stability.
