You see it works like this, in the type chart's code (starts at offset 3e474) for each resistence/weakness there are 3 bytes, the first byte is the byte of the type that is attacking (Ghost's byte is 08 and Psychic's is 18), the second byte is for the type that is taking the move and the third byte is what determinates if it will be super effective or not (00 for immunity, 05 for not very effective and 14 for super effective). This whole shit happened because Game Freak put "00" instead of "14".
