⚠️ Disclaimer

The write (export) feature is experimental and may cause unintended behavior, including overwriting game assets.

Use at your own risk.
I am not responsible for any damage, corruption, or loss resulting from use of this plugin.

Editing files from multiple projects simultaneously is not recommended —
the plugin temporarily stores the original encrypted header in memory, and concurrent modifications may lead to corrupted headers or data loss.
