You know, there is a Tre' dropping machine emulator that works quite well. (even on mid-range PCs) Actually there are a couple of them. Chankast is one of them, and I believe it worked quite well. I played Ecco on it. (We are talking about the DC right?)
Well then, hunt down the newest version of Chankast. It should aid in said dropping of these tres when the tre dropping machine is unavailable. I believe I still have a nice DC boot disc sitting around too.
