Basically adds the Pokemon Radical Red changes (New Moves, changed types, BST alterations, etc.) into Pixelmon.

This doesn't add the new abilities because those are hard-coded.
You can use this in your maps and stuff I don't care just don't reupload it and claim it as your own.
In other words: Have some common sense.

EDIT: This pack IS NOT tested for 1.20 Pixelmon and I cannot guarantee it will still work. An update is being worked on to match the latest version of the Radical Red ROM hack, including all changes made to all Gen IX Pokemon. You will need to use a different data pack to enable any unobtainable Gen IX mons to spawn.
