 - Katana inventory : Link Between Ability ID and katanas
 - Weapon inventory : shurikens and ball (? to be confirmed)
 - Jump is forced as hostile

 - Item inventory and weapon inventory direct flag is forced ON
 
BUGS 
 - Throw item is move instead of 4
 - Short CT is not correctly checked (0x80 instead of 0x08)
 - No CT is not correctly checked (0x40 instead of 0x04)
