M4v,
It made up for all those shots from the dark that kept happening. Another good one was hearing a door opening and closing over and over again in the distance. Time it right, and you'd get there with the alien facing the wrong way.
A game glitch in TFTD was the corner glitch- sometimes you'd get up near a corner just right, and could see aliens inside a building or UFO, and sometimes even take shots. The shots only would get through if you were right up against the corner, however. Aliens that tried this trick normally shot from some distance away, and only managed to either hit the side of the sub, or hit another alien.
I've got some screenshots showing Amy and Tails in Emerald Coast- I took them using my video capture card. It's pretty easy to get Tails in, Amy is a bit harder, but not much. I don't know if this glitch works in the GC version, but as you can see, it does in the DC one.

Assuming anyone plays or is interested in Sonic games anymore, of course. The series has been rather spotty in terms of quality lately.
