Before opening the tool, you must understand the Golden Rule of modding:

ALWAYS BACKUP YOUR FILES. Never edit the original game .unity3d files directly. Make a copy of the file you intend to edit and place it in a safe folder. If you break the file, you can simply replace it with your backup.

What you need:

The tutorial's fix was manual but clear:

Maya took a deep breath. She unzipped the folder completely. Inside costumes/, she found star_vortex_03.svg (the ZIP had automatically changed the slash to an underscore—but Scratch's internal JSON still wanted a slash).

She renamed the file to star_vortex_03.svg (no slash, no issue). Then she opened project.json again, searched for "star/vortex", and changed it to "star_vortex_03.svg". sb3utility tutorial

The tutorial said: Make sure every asset listed in project.json actually exists in the folder.

She checked all 48 costumes. All present. All safe names.

To download SB3 Utility, visit the official GitHub repository and follow the installation instructions for your operating system.

When you open SB3Utility, the interface can look intimidating. Here is the breakdown of the main tabs:

Many modern mods use a “mod folder” approach to avoid overwriting original files:

This method keeps your installation clean and allows easy uninstallation.

For power users, SB3Utility includes a built-in script editor that exposes the raw project.json. This allows you to batch-edit code.

Example: Change every "wait 1 secs" block to "wait 0.5 secs"

Advanced Tip: You can inject entire custom blocks or hack the "pen" extension to run faster by modifying the argument limits in the JSON. (Note: This may break compatibility with the strict Scratch editor). ALWAYS BACKUP YOUR FILES

Now came the magic. The tutorial instructed: Recompress the folder into a new .zip file, then rename the extension back to .sb3.

Maya selected all the inner files (not the folder itself—the tutorial was specific about that), right-clicked, and chose "Compress." A new Archive.zip appeared. She renamed it to cosmic_rescue_FIXED.sb3.

Her finger hovered over the mouse button. If this failed, she had no backup.

She double-clicked.

The green flag appeared. The Scratch editor loaded. Sprites appeared. Gloop wiggled his antennae. The hyperdrive button was ready.

It worked.
