In the Mystic Ruins, where you got the fighting gloves with Knuckles, on that ledge you'll see a tree sticking up above the other trees. Glide into it (it is hollow) and there is a secret emblem. This is also available to climb with Knuckles (it is the big tree at Big's house).
First of all You must be Sonic. Then go to Station Square and find a manhole by the shop where you get the gold chao egg. Jump into it. Then you will be in the sewers. In the sewers you will find a raised platform and a little porch like thing popping out from the wall. Jump onto it then go left and there you go! You got the Speed Shoes! Hint: After you get the Shoes keep going forward and a wind (or some thing. I can't remember now) will take You to the shop where you get the gold chao.
Place the game disc in a PC compatible CD-ROM drive to find several rendered images from the game.
On the jump panels fall off the third panel. Then go behide the rock and there should be a extra life.

Play in Casinopolis with Sonic and go to the pinball game with the NiGHTS motif. Hit the three little purple point givers in order to open up an entrance at the top of the board. Then make your way through the secret entrance. You'll now be in another NiGHTS motif pinball game. Whenever you fail to catch Sonic with the bumpers, don't worry about losing a ball. Instead, Sonic will be transported through a world very familiar to the NiGHTS level Splash Garden.
