This resource pack contains some minor changes to textures to revert them to their older state in various past versions of Minecraft.
The reverts are: poppy (is now rose), water (is now blue), dispenser and dropper (cuter like originally), oak sapling, nether quartz ore, cod and pufferfish (also in entity and bucket form), and some other food items.

The proper order of priorities for all my "Classic" resource packs is as follows:

1. Classic Beta
2. Classic Retro
3. Classic Core
