I did talked about this a bit while chatting on this site and it's true. I have both Sonic Adventure 2: Battle and Sonic Heroes both for the GameCube and I can prove to you since I did do this a long time ago.

In Adventure 2: Battle, go to 2P mode and select Amy (either 1st, or 2nd player), select City Escape and go to an area where the camera is really close to the characters. Then turn Amy to her back and you can see her underwear. If you use her whistle, you can completely see her underwear.

And in Sonic Heroes, simply select Big while playing Team Rose. Then simply press B to make Amy and Cream sit on Big's shoulders, then use the yellow C joy stick and turn the camera to where you can see Amy and Cream's underwear.

OMG! They wear white! Only perverts would want to try this out.
