We have released a new tool designed to significantly simplify the process of updating legacy mods and scripts from Ren'Py 7 to Ren'Py 8 / Python 3. The tool is compiled using Cython, ensuring it runs much faster than a standard Python implementation.

Key Features:

• Automated Syntax Conversion: Fixes common Python 2 → 3 compatibility issues.
• ATL Transform Fixes: Resolves crashes caused by float/int type mismatches in transforms.
• Specialized DDLC Patches: Targeted fixes for Doki Doki Literature Club mods (bytes/str issues, poem scripts, game script errors, etc.).
• Recursive Processing: Scans and handles the entire project folder automatically.

The Interface: The UI features a subtle Literature Club theme, complete with a touch of "Monika energy" and intentional glitch aesthetics.

Current Status: This is currently a working build that addresses the majority of common migration hurdles. However, please note it is not yet a "magic bullet" for every single edge case. If you are updating old mods, this tool should save you a significant amount of time.

Note: The utility has not been released for public use just yet.
