It was replaced by an innocuous Casinopolis decoration. One of the more infamous and well-documented changes from the original 1998 Japanese version would be the stylized cowgirl billboard that possibly is inspired by the real life Vegas Vickie sign and waves a 3D martini glass in the Casinopolis action stage, which made suggestive moans whenever it was attacked or jumped on. It should be noted that the distortion effect can only be seen with Sonic's regular shoes - with the Light Speed Shoes, Sonic's feet won't distort at all. A similar effect would only surface 15 years later in Sonic Lost World. It was probably removed due to being very difficult to see during regular gameplay. All Dreamcast versions of Sonic Adventure distort Sonic's feet at this speed, but only the original Japanese version blurs it. However, this can only be seen when Sonic runs at absolute maximum speed, coming off of a spin dash or dash pad (simply running in one direction is insufficient). It is subtle and similar to the blurs used for Tails' tails and spin jumps. In the original Japanese releases only, Sonic's running animation in top speed has a unique blurring 'wheel' effect akin to the classic games. The US 1.1/European version added a ripple effect to the background and shine to the foreground, and the International included its subtitle. The title screen went through four different iterations the original Japanese and US 1.0 release was just a static image that didn't have a fade in.
