Welcome to the Betrock wiki!

These pages will mostly describe how the McRegion world format is constructed, and how it's data is to be interpreted, up to Beta 1.7.3, adding onto what's already available on pages such as.

• Region file format
• NBT format
• Minecraft ID List

This is to aid both the development of Betrock, and the development of future, non-notchian Beta 1.7.3 Clients.
