Sonic the Hedgehog Hints & Cheats

By finding and obtaining the six Chaos Emeralds hidden throughout each zone and completing the game, you get to watch the true, better ending sequence.

In the second act of the Green Hill zone, after the pit of water, there is a spring. Hit the spring and jump so you hit the corner of the wall. if done corect, sonic will get stuck on the wall and if you jump to the right, sonic can go to the nearest place above him (the waterfall leading to the chaos emerald)
