Minecraft Indev level format
From Just Solve the File Format Problem
Minecraft Indev level format is a data format used in an old version of the Minecraft game (Indev 0.31). This and other Minecraft formats are extensively documented in the Minecraft Gamepedia wiki.
This format is based on the Minecraft NBT format, and is different from the Minecraft Alpha level format even though that also is based on the NBT format.
