100% discovered study 03.15.2026
Currently on version 1.58 we have 100% discovered maps for both games. In ETS2, guide and files for previous version is still actual, so I did not do updated version.
However, in ATS, we received a major map update with the Route 66 rework and new guide is here. But we’re expecting the Illinois DLC soon, so new challenges ahead.
All news as always comes first on telegram channel and Patreon subscribers.
ATS 1.58 – 100% Explored map with all DLC (March 2026, all map DLCs and latest Route 66 Rework)
[Guide] ETS2 1.57 – 100% Explored map with all DLC (with Nordic Horizons) (January 2026, all map DLCs including Nordic Horizons) Actual to 100% on ETS2 1.58
I do these discovery since 2017 and I discover whole map almost on every game versions including all expansions and reworks.
How to Merge Map Progress in Profiles for ETS2 and ATS – 2026 Guide
New game versions updates are here so we will also see the mods updates and it is perfect time to make you perfect profile.
In this guide I explain how to merge several profiles map discovery progress on example of merging vanilla 100% and Promods 87% profiles on ETS2 1.58. You can try this scheme on future versions in both ETS2 and ATS. Below you can find link to text version, tools and also ready strings used in this video.
Guide:
1. Reason
There are several reasons. The most common one:
You play vanilla + DLC on one profile. And you play mod maps like Promods or Roextended on another profile.
Keeping them separate is fine. But what if you want:
- Your 100% vanilla discovery
- Plus your mod map exploration
- Combined into one master profile
Another reason:
You created a new profile for TruckersMP or testing purposes. And later you want your original progress back
Or maybe you lost progress after an update and want to rebuild quickly.
In all these cases — merging discovered map items makes sense.
Important:
In this tutorial we are merging only discovered map items.
We are not merging:
- Garages
- Money
- Drivers
- Trucks
- XP
That is a completely different topic.
2. What Was the Problem With the Old Method?
My year-old guide is still mostly actual and you can still use Notepad++ or other editor but new guide can save you hours. Let me remind you that in every profile, discovered roads are stored in a strict indexed order inside the game.sii file.
If you simply copy part of the data:
- The order becomes incorrect
- Duplicate entries appear
- The profile may crash
- Or the game may behave unpredictably
And this becomes a serious problem because:
- Vanilla profiles contain thousands of discovered entries
- With map mods, this can grow dramatically
Manually fixing that with Notepad++ used to require:
- Regex
- Manual renumbering
- Removing duplicates
- Reindexing everything from zero
It worked — but it was slow and error-prone. So today we go another way. We automate the process using a Python script.
3. Make backups!
If you plan to modify game files always Make backups! This is extremely important.
Your profiles are located by default in: Documents/ETS2/profiles or Documents/ATS/profiles
Copy the entire profiles folder somewhere safe. If something goes wrong, you restore everything in seconds.
Disable Steam Cloud synchronization for all profiles involved. We cannot modify profiles that are stored only in Steam Cloud. After disabling Steam Cloud, profiles will be saved locally in the Documents folder.
4. Preparations and tools
As always for manipulations with the profiles we need several tools:
Truck Tools for save decryption – it is free of charge application you need to install to make various actions with you profiles in both games. You can also use your preferrable tools for game files decryption
https://trucksim.top/trucktools
Sublime Text – we need good text editor that allow us to run big files. While I use Sublime, you can use your preferable text editor like Notepad++ or even VS Code.
https://www.sublimetext.com
Python installed on your system – it will run my script. Python is also free of charge.
https://www.python.org/
The merge-discovered.py script – you can download the script for free
https://sharemods.com/uig6zgjgicrf/merge_discovered.zip.html
How to use Python?
1. Go to the official website: python.org
2. Download the latest stable version for Windows.
3. Run the installer.
⚠️ Very important: Before clicking “Install”, check the box: Add Python to PATH This is critical. If you skip this, the `python` command will not work in Command Prompt.
4. Click Install and wait.
5. That’s it.
How to Check If Python Is Installed?
Open Command Prompt and type: python –version or py –version
If you see something like: Python 3.x.x You’re ready to go.
If you see an error like “python is not recognized”, then:
Either Python is not installed
Or it was installed without adding to PATH. In that case, reinstall and check the PATH option.
Before starting
1. Make sure all profiles you plan to modify have Steam Cloud disabled.
2. If merging modded profiles, verify that all required mods are present in your mod folder.
3. Enable file decryption in config: g_save_format 2
4. Enable console: uset g_developer 1 and uset g_console 1
5. Make sure all profiles are from the same game version (don’t combine ATS profiles with ETS2 profiles and vice versa)
5. Prepare profiles
Enter each profile you want to merge.
Create a new save to identify them easily by timestamp.
Decrypt each profile using Truck Tools.
Inside each profile, locate the file: game.sii and copy them one by one to a new folder.
6. Merging Process
With the old method, you had to manually clean and reorder everything in Notepad++. With the new method, we only extract the necessary data in seconds.
Instead of manually:
Removing prefixes
Reordering numbers
Re-adding brackets
Generating incremental indices
Removing duplicates
We now use a Python script that:
Extracts all discovered item IDs
Removes duplicates automatically
Reorders them correctly
Recreates properly indexed discovered items entries
Outputs a ready-to-paste result
Shows you stats
Collect all game.sii files from desired profiles in one folder.
You can rename them as you wish, just make sure that they have .sii extension. Example profile3.sii or promods.sii etc.
Put the script merge_discovered.py to the same folder.
Open terminal or command prompt in the script folder (right click with Shift – Open Powershell window here) and type: python merge_discovered.py
or py merge_discovered.py
Press enter
The script will:
Detect all `.sii` files in the folder
Show how many items were found per file
Show total collected items
Show duplicates removed
Generate output file: merged_discovered.txt – fully indexed and ready to paste.
Then Open the target profile’s `game.sii (The profile in which we want to get results of merge)
Replace its `discovered_items` block with the newly generated one.
Save the file.
Open the save in the game.
Enjoy the results.
One known side effect
Recruitment agencies may not work properly after modifying discovered items. If you attempt to hire new drivers after merging, the game may crash.
Recommended workaround: Hire all drivers you need before modifying profiles.

[February 2026] No more 99.99% on Promods 2.81 (1.58)
Quick reminder: for a long time I’m trying to discover Promods for 100% but unfortunately peak score I had is 99.99% and after each map mod update and new SCS expansions, these numbers are decreasing. For instance – I had 99.99% on Promods 2.77 but when Promods 2.80 for ETS 2 1.57 released I got only 88.70%. 2.80 was a big update and brought integration with Nordic Horizon DLC and Scandinavia refresh and new content to the mod. I haven’t combined it with discovered NH DLC areas from different profile (which is 100%).
And after release of 1.58 version (and Promods 2.81) my progress is on 87.86%, so I’m gonna merge it with main vanilla profile and maybe will share it with my Patreon subscribers. And will hit the road of new undiscovered roads. Who know how much time it will take to reach again at least 99.99%. I’m sure you can do it faster.
So below you can grab my progress strings for 2.77 and get those 99.99% and wait for bigger numbers or discover those 12% on your side in Promods 2.81 (or maybe you will reach 100%).
On the video below you can find PM 2.77 on ETS2 1.57 progress and also I’m sharing the link to guide how to merge profiles.

100% discovered study 02.24.2026
With version 1.58 of both games, the situation is a bit different.
In ETS2, we still have 100% map completion, and the guide below remains fully up to date.
However, in ATS, we received a major map update with the Route 66 rework. With the American guide below, you will now reach only about 96% completion out of the box. I’m still running deliveries and haven’t reached 100% yet. Most likely, I will skip this version and won’t create a dedicated guide for it.
The reasons are quite simple: time is very limited on my side, and there’s relatively low audience interest in ATS 100% guides. On top of that, we’re expecting the Illinois DLC this spring.
That said, if I finish my discovery soon and see no signs of ATS 1.59 or a new map expansion by the end of March, I may share the updated strings — at least for Patreon subscribers.
[Guide] ATS 1.57 – 100% Explored map with all DLC (with Louisiana) (December 2026, ATS 1.57, all map DLCs with Louisiana) Actual to 96% on ATS 1.58
[Guide] ETS2 1.57 – 100% Explored map with all DLC (with Nordic Horizons) (January 2026, ETS2 1.57, all map DLCs including Scandinavia Rework and Nordic Horizons DLC) Actual to 100% on ETS2 1.58
I do these discovery since 2017 and I discover whole map almost on every game versions including all expansions and reworks.
100% discovered study (last on 1.57) 02.01.2026
We finally have full 100% discovered maps for ATS and ETS2 within version 1.57, but new challenges ahead. New games version is around the corner and at least in US we have massive map rework with Route 66 project. In Europe we will probably will not see Benelux Rework changes very soon. So now we have some time to hold and enjoy games.
[Guide] ATS 1.57 – 100% Explored map with all DLC (with Louisiana) (December 2026, ATS 1.57, all map DLCs with Louisiana)
[Guide] ETS2 1.57 – 100% Explored map with all DLC (with Nordic Horizons) (January 2026, ETS2 1.57, all map DLCs including Scandinavia Rework and Nordic Horizons DLC)
I do these discovery since 2017 and I discover whole map almost on every game versions including all expansions and reworks.
100% discovered study 01.24.2026
Currently we have 100% in ATS 1.57 with new Louisiana DLC and you see the guide below but in Europe took more time than I expected so probably ETS2 guide with Nordic Horizons and Scandinavia rework won’t be finished in January. Update is really big so it’s deserved to wait a little. For sure all the hidden roads will be in it but you can watch them right now in the video. The full guide is also still not ready but I hope this weekend it will be available on Patreon. But for 100% in ETS2 1.57 expected date is February 2026. If you’re using older strings (for instance for 1.56 below) they are still work but undiscovered areas will remain grey.
[Guide] ATS 1.57 – 100% Explored map with all DLC (with Louisiana) (December 2026, ATS 1.57, all map DLCs with Louisiana)
100% Discovered Map of ETS2 1.56 (Profile and save game) (September 2025, ETS2 1.56, all map DLCs up to Greece, not includes Scandinavia Rework and Nordic Horizons DLC)
I do these discovery since 2017 and I discover whole map almost on every game versions including all expansions and reworks.
100% discovered study 01.09.2026
If you are a fan of ETS2 and ATS maps discoverability, like I am, and have no time and desire to visit every small part of map, then Trucksim is the best source since periodically after the game updates, new expansion and reworks I discover the roads and cities and share not only profile but also a text version with strings which you can inject to your game.sii and get the same results in couple minutes. Unfortunately it consumes a lot of my time and effort (both discovery and video guides). But I receive in return your positive feedback, likes and guides views on Youtube.
I’m trying to optimize the process and e.g. for American Truck Simulator do AI voiceover and reuse the guide so the ATS tutorial video many times faster (and I share this more often.)
Currently we have 100% in ATS 1.57 with new Louisiana DLC and you see the guide below and I’m on the home stretch in Europe as well so probably ETS2 guide with Nordic Horizons and Scandinavia refresh will be done in January. As well as secret roads guide.
If you’re using older strings (for instance for 1.56) they will sill work but undiscovered areas will remain grey.

How to Merge Map Progress in Profiles for ETS2 and ATS – 2026 Guide
New game versions updates are here so we will also see the mods updates and it is perfect time to make you perfect profile.
In this guide I explain how to merge several profiles map discovery progress on example of merging vanilla 100% and Roextended 89% profiles on ETS2 1.53. You can try this scheme on 1.57 and in both ETS2 and ATS. I have currently 100% in US and bout 93% in Europe so below you can find links to ready strings to latest versions.
Guide:
1. Reason
Merge discovered items in two profiles let you have updated visited roads in the end even if you exploring maps on different profiles. Also when the new version of the game is being released you can again discover as much as possible and then merge with your old combined profile.
2. Preparations and tools
Download and install software we plan to use – TS SE Tool, Notepad++, make sure that you have mods in mod folder if you plan to merge mod’s profile, make sure that Steam cloud disable for all profiles which will be changed, check config file if you can decrypt game files (g_save_format 2) and can use console (uset g_developer 1, uset g_console 1) and so on.
3. Backup
Backup all the profiles to the separate drive before doing any manipulations.
4. Profiles job
Enter to the profiles you wish to merge and save game to locate desired profiles by timestamp. You should carefully pick correct profiles. Decrypt profiles one by one and open game.sii in each mergeable profile and copy all discovered items to new text file (in this file we will merge them). We can merge 2 or more profiles but don’t forget that it should be from the same version of the game.
5. Merge (most important part)
When all discovered items strings pasted to the text file we have to change the order of numbers – the way as game read each string. Start from removing left part of the string (discovered_items []: ) with Notepad ++ command Find and Replace (Ctrl+C). On the Find what enter discovered_items \[\d+\]: and keep blank on Replace with (we have to remove them). Do not forget check Regular Expression in Search Mode. Replace all and you will get list of numbers. On this step you can also remove duplicates. Now we have to return discovered_items []: text with empty brackets. Alt+C and choose Text to insert and place there discovered_items []: and push ok. On the next step we have to add numbers to the brackets with correct order from 0. Select all in bracket spots (Choose first one and with Alt+Shift select last one) and again Alt+C and choose Number to insert – Initial should be 0, increased by 1, format decimal. Push ok and wait. If you have lot of string it can take a while. When all numbers added to brackets we can remove redundant spaces. Now we can copy strings and paste them to the target profile where will me merged result.
6. Results we get
We have to see discovered roads from 2 or more profiles we combined.
7. Back to play Load from profile where strings added and if you see desired result you can back to game but please bare in mind that recruitment agencies are not gonna work with this method so if you want to hire drivers you game will probably crash. To avoid it hire drivers before profiles modifications.

Promods 2.80 for ETS 2 1.57 which just released brought not only integration with Nordic Horizon DLC and Scandinavia refresh but also new content to the mod and my discovered items with 99.99% is not actual anymore. Currently I have 88.70% and later maybe I will combine it with discovered NH DLC areas from different profile. But for now I have not 100% in main ETS2 so it will take time and have to bear in mind that PM 2.80 nordic regions are not equal to the vanilla DLC (E.g. Kirkenes, Murmansk area).
So below you can grab my progress strings for 2.77 and get those 99.99% and wait for bigger numbers or discover those 11.3% on your side in Promods 2.80.

100% discovered study 12.27.2025
It is so many map related news in our favorite truck simulator games, so on my side most previous guides and files are currently outdated. But I have some progress – ATS on 1.57 with new Louisiana DLC is almost done and the guide will be released in 2025, but in Europe I have only 92.75% with Nordic Horizons and Scandinavia refresh. So European update will take time and will be released in 2026. I concentrated on finding secret roads as well so while in US it is all shown in video, for Nordic Europe I found dozen of roads and discovery is still goes on.
If you’re still on 1.56 below you can find guides for both games. They will work on newer versions but undiscovered areas will remain grey.
100% Discovered Map of ETS2 1.56 (Profile and save game) (September 2025, ETS2 1.56, all map DLCs up to Greece)
100% Explored map with all DLC in ATS 1.56 * Full Map Discovered, Guide, Profile (September 2025, ATS 1.56, all map DLCs up to Iowa)
Since 2017 I discover whole map almost on every game versions including all expansions and reworks. Some map updates take a lot of time but some is pretty small and can be discovered in couple days. Nordic Horizons, refreshed Scandinavia and Louisiana will probably finished in 2026. And as soon as my progress will be finished I will share it on Youtube and here the blog.
