Unchanged World

Requires UniMixins

This mod adds the 1.6.4 world generator to 1.7.10.

1.7 was "The Update that Changed the World"

Unchanged World adds a new world type, Default 1.6.4, that generates worlds exactly the way Minecraft 1.6.4 did.

Create a new world, open More World Options and click World Type until it is Default 1.6.4.

Existing worlds keep the generator they were created with. On a server, set level-type=default_1_6_4 in server.properties before the world is created.

1.7 blocks that 1.6.4 never generated, such as packed ice, red sand and the new flowers, will not appear in the terrain.
