Let RP come back here

This mod solves the compatibility problem of resource packs created for new Minecraft versions with older game versions. When a resource pack author uses only the modern metadata format and the old game version cannot read it, the mod automatically converts the metadata, allowing the pack to be loaded again.

For example, resource packs for version 1.21.9 can be loaded in this version (since the pack_format parameter has become optional), but if you want to use them in version 1.21.8, you would have to manually edit the mcmeta file and restore the pack_format parameter. This is extremely inconvenient, especially when you need to modify multiple resource packs.

Important warning: If the resource pack author explicitly states that their work no longer supports older versions, but you still load it through this mod and errors occur, please do not report this to the author. This will create additional problems for them.

Automatic Conversion

After you have verified that resource packs can work in older versions without serious errors (or without any at all), the mod automatically generates the necessary fields according to the new mcmeta format of version 1.21.9 when they are missing:

• pack_format
• supported_formats
