The original Minecraft menu panorama
Have some nostalgia for the original menu panorama used from Beta 1.8 to Release 1.12.2, now in higher quality due to the world seed (2151901553968352745) being found.
This pack comes in two forms – one with the original Minecraft textures, and one with the modern Texture Update (1.14+) textures.
The pack.mcmeta file specifies that this pack is only for 1.17, but just change the pack_version if you want to use this for older versions of Minecraft.
