A double resolution texture pack that continues Vattic’s original Faithful 32x32 pack with the classic textures.
Find the version you are looking for, and from there follow the instructions below:
Unzip the file using any program like Winrar, 7zip, or Archive Utility. Sometimes GitHub has a bug where the folder that is created when decompressed has a second folder within it, breaking the structure. To solve this, simply drag the second folder inside the decompressed one into your resourcepacks folder. Sorry for the inconvenience.
