The mod takes an applied texture pack (if it's 1.8), copies it, changes all the files to fit the new game versions, and applies that to the game.

This is useful for anyone looking to use an old resource pack that has been discontinued.

This is a beta version, the release will have better compatibility, more versions that it supports, and will be way faster.

Legacy Packs

Legacy Packs lets you use old resource packs — the kind made for Minecraft 1.7 and 1.8 — on modern versions, without editing a single file.

Back in the day, textures lived in folders like textures/items/ and textures/blocks/, and many were packed into single sprite sheets. Modern Minecraft expects textures/item/, textures/block/, individual sprite files, and a different chest texture layout. Legacy Packs bridges that gap automatically while the pack loads.

Features

• Translates old texture paths to the modern format (e.g. items/apple.png → item/apple.png)
• Slices old combined sprite sheets into the individual textures modern Minecraft expects
• Remaps chest texture UVs and splits double-chest textures to the new format
• Works on the fly — drop in any supported pack and enable it like normal; no manual conversion

Requirements

• Minecraft 1.21.x
• Fabric Loader 0.18.1+
• Fabric API
• Java 21+

Client-side only.
