Nether Bedrock Cracker

Nether Bedrock Cracker (1.21, 1.20.1) cracks nether seeds from bedrock. This works in versions 1.18 and above since bedrock became seed dependent in that release. The overworld uses a different RNG, so the calculations used here are not applicable.

How to use:

• Collect bedrock positions from both the nether floor and the nether roof.
  • Collect data from both the floor and the ceiling. Gathering data from only one side will result in less informative results.
  • Focus on collecting bedrock data on y-level 4 or y-level 123, as bedrock is rarer in those layers, providing more valuable information per block.
• After gathering the required data, you have two options:
  • Run the cracker and view the cracked seeds in the graphical user interface (GUI).
  • Run the cracker and save the found seeds to a file.

Requires:
