Turn received item into blue rupee

// This function takes an item value as input, then returns FF if the item doesn't use a slot. If it does use a slot, then it can return FF or some other value. Basically, this function is used to determine if an item has already been obtained (the slot is filled), which is used to convert items into blue rupees.
