LimebrellaSharp

🍋☂️ LimebrellaSharp - What is it :interrobang:

This app can unpack and pack archives encrypted with the 1st version of “Lime” encryption. It can also re-sign these SaveData files with your own SteamID to use anyone’s SaveData on your Steam Account.

Supported titles

Resident Evil 4 (Remake)	2050650	Steam

🤯 Why was it created :interrobang:

I wanted to share my SaveData files with a friend and find out why the game takes so long to load my SaveData files.

:scream: Is it safe?

The short answer is: No.

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

:scroll: How to use this tool

[GUI] - 🪟 Windows

On Windows, you can use either the CLI or the GUI version, but in this chapter I’ll describe the latter.

BASIC OPERATIONS

1. Setting the Input Directory

You can set the input folder in whichever way feels most convenient:

• Drag & drop: Drop SaveData file - or the folder containing it - onto the TextBox (1).
• Pick a folder manually: Click the button (2) to open a folder‑picker window and browse to the directory where SaveData file is.
• Type it in: If you already know the path, simply enter it directly into the TextBox (1).

2. Entering the User ID

In the case of Steam, your User ID is your Friend Code.

3. Re-signing SaveData files

If you want to re‑sign your SaveData file/s so it works on another Steam account, type the User ID of the account that originally created that SaveData file/s into the TextBox (3). Then enter the User ID of the account that should be allowed to use that SaveData file/s into the TextBox (5). Finally, press the “Re-sign All” button (9).

4. Accessing modified files

Modified files are being placed in a newly created folder within the “LimebrellaSharp/_OUTPUT/” folder. You may open this directory in a new File Explorer window by pressing the button (10).

[!NOTE] After you locate the modified files, you can copy them into your save‑game folder. For Steam, the path looks like this: “<STEAM_INSTALL_DIRECTORY>/userdata/<USER_ID>/<APP_ID>/remote/win64_save/”

ADVANCED OPERATIONS

Enabling SuperUser Mode

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

Unpacking SaveData files

[!IMPORTANT]
This button is visible only when the SuperUser Mode is Enabled.

If you want to unpack SaveData file\s to read its content, type the User ID of the account that originally created that SaveData file/s into the TextBox (3), and press the “Unpack All” button (6).

Packing SaveData files

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

OTHER BUTTONS

Button (8) cancels the currently running operation. Button (4) swaps the values in the “Steam ID (INPUT)” and “Steam ID (OUTPUT)” TextBoxes.

:fire: 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.
Application stores up to two log files from the most recent sessions.

[ISSUE] Game doesn’t detect SaveData file\s on Steam

If you purchased the game on Steam and it doesn’t detect your re‑signed SaveData files after you’ve placed them in the correct folder, the issue is usually that a valid remotecache.vdf file also needs to be generated.

Instructions on how to generate a proper remotecache.vdf can be found in this gist.

[ISSUE] Not all controls are visible in the WPF application on Windows

You probably have your Windows system font size set higher than the default. Set the font size back to the default value, or press CTRL + SHIFT + J to unlock window resizing in the application.
