💿 AutostrongSharp - What is it ⁉️

This application can decrypt and encrypt SaveData files from various games running on RE Engine. It can also resign these SaveData files with your own SteamID to use any SaveData on your Steam Account.

🤯 Why was it created ⁉️

I wanted to share my SaveData files with a friend, but they were incompatible with his Steam Account.

😱 Is it safe?

The short answer is: No.

Caution

If you unreasonably edit your SaveData files, you risk corrupting them or getting banned from playing online. In both cases, you will lose your progress.

Important

Always back up the files you intend to edit before editing them.

Important

Disable the Steam Cloud before you replace any SaveData files.

You have been warned, and now that you are completely aware of what might happen, you may proceed to the next chapter.

📜 How to use this tool

MainWindow

Setting the Input Directory

There are three ways to achieve this. The first one is to drop the SaveData file or a folder that contains it, onto a TextBox (1) or a button (2). Alternatively, you may use a button (2) to open a folder-picker window and navigate to the directory with it. You can also type the path to the folder in the (1) TextBox.

Tip

The program will extract the Steam32_ID from the "Input Folder Path" TextBox (1), if it ends with "<steam_id>\<steam_appid>\remote\win64_save", and will fill the TextBox (3) for you.

About Steam32 ID

It is a 32-bit representation of your 64-bit SteamID.

Example:
64-bit SteamID 32-bit SteamID
76561197960265729 1

Note

Steam32 ID is also known as AccountID or Friend Code.

Tip

You can use the calculator on steamdb.info to find your SteamID.

Resigning files

If you want to resign your SaveData files so you can use them on another Steam Account, type in the Steam32_ID of that Steam Account into a TextBox (3). Once you have it typed in, select the Game Profile (4) corresponding to the game from which the save file comes, and press the "Resign All" button (10).

Enabling SuperUser Mode

Warning

This mode is for advanced users only.

If you really need it, you can enable SuperUser mode by triple-clicking the version number label (11).

Decrypting files

Important

This button is visible only when the SuperUser Mode is Enabled.

If you want to decrypt SaveData file\s to read its content, select the Game Profile (4) corresponding to the game from which the SaveData file comes, and press the "Decrypt All" button (7).

Encrypting files

Important

This button is visible only when the SuperUser Mode is Enabled.

If you want to encrypt the decrypted SaveData file\s, select the Game Profile (4) corresponding to the game from which the SaveData file comes, and press the "Encrypt All" button (8).

Backup functionality

By default, the backup option is checked (5). In this state, the application will back up files before each operation to the new folder inside the "AutostrongSharp/_BACKUP/" directory. This app can create up to 3 zip archives.

Open the Backup Directory

You may open the "AutostrongSharp/_BACKUP/" directory in a new File Explorer window by pressing the button (6).

Other buttons

Button (9) cancels the currently running operation.

🔥 Issues

All the problems I've encountered during my tests have been fixed on the go. If you find any other issues (which I hope you won't) feel free to report them there.

Tip

This application creates a log file that may be helpful in troubleshooting.
It can be found in the same directory as the executable file.

IF YOU DO NOT SEE SAVEDATA FILES THAT YOU HAVE RESIGNED, IN THE GAME MENU, THEN PLEASE, READ THIS DOCUMENT.
