Quote:Bit 0: if 1, character is a ghost
Bit 1: if 1, race startup sequence drive to the starting line
Bit 2: Unknown
Bit 3: If 1, camera movement at finish line
Bit 4: if 1, character is CPU controlled
Bit 5: if 1, character can't move, race has not started and waiting on Lakitu
Bit 6: If 1, character is human controlled
Bit 7: If 1, character exist, if 0 character doesn't exist.
