Minecraft Resourse Pack to beta 1.7.3 Texture Pack converter

A simple Python script that converts a Minecraft resource pack into a texture pack compatible with beta 1.7.3. It removes unsupported file formats and modern metadata so the resulting .zip can be loaded directly in your Beta 1.7.3 instance.

This script works quite well, but there are some flaws that will need to be corrected manually. Anyway, I think it's better than doing everything manually.

🚀 Usage

1. Download or clone the script main.py
2. Download resource pack you want to backport to beta 1.7.3, like this one (This resource pack is not mine; all rights belong to its author).
3. Download a texture pack template for beta 1.7.3, such as this one (This texture pack is not mine; all rights belong to its author).
4. Run the script:

   python3 main.py modern-resourcepack.zip example_beta1.7.3_pack.zip

   Example:

   python main.py steelfeathers-enchanted-pack_v1.6-1.2.5.zip legacypack-2025-32x.zip

5. A file like modern-resourcepack_converted_b1.7.3.zip will be created.
6. Drop converted texturepack file into texturepacks/ folder in your Minecraft Beta 1.7.3 instance, enable it in-game, and you’re good to go!

How it works

• Reads a resource-pack.zip file made for Minecraft (For example 1.2.5)
• Filters out assets/… folders, .mcmeta and .json files (Beta doesn't support these)
• Writes the remaining files into a new .zip archive with the folder structure Beta expects (terrain.png, gui/items.png, etc.)
• Outputs a clean .zip you can drop directly into Beta 1.7.3 texturepacks/ folder.
