Most of the time when I play Sonic Adventure on the Dreamcast, I do this weird thing you can do at the entrance to Windy Valley:

Sonic is Jeebus.png

If you spin dash into a certain part in behind the entrance, Sonic will just stand there.

On air.

EDIT: I tried, and you can't do this on the DX version.






On a side note, I love how nullDC can make the games widescreen. You know, how SA on PS3, XB360 and Steam was supposed to be?
