That's only the Python Script, I don't know if he only wants that but also wants the Table or what...
One interesting thing to note is that 0x13 (the number listed as Zen Headbutt's bitfield) corresponds to 00010011, which, reversed, corresponds to:
contact: yes (1)
protect: yes (1)
magic coat: no (0)
snatch: no (0)
mirror coat: yes (1) //error
king's rock: no
critical chance: no (0)
padding: 0
This then tells us that the real number should be 00000011, or 0x03
King's Rock note: All moves that actively deal damage and do not already have a chance to flinch will gain a 10% chance of flinching the opponent. (This chance doubles to 20% if the holder has Serene Grace.) This effect does not stack with Stench, and is not affected by Sheer Force.
