edit1:cleaned up the synth item code and added a few more items. you're welcome kensuhan.
edit2: changed the values for the useable items, this'll hopefully keep the inventory from glitching out.
edit3: removed some more dummy items from the synth item list, and updated the dummy item code accordingly.
