Back to Battle City: Part 1 - S3-E25
Continuity mistake: When the main characters walk inside the tower, in the wide shot of Roland saying the Battle City finals will take place there, all of the characters are facing the same direction. In the next shot, Yugi, Joey, and Tristan are all facing different directions from one another. Also, the other characters cannot be seen in the shot next to them, even though they were all standing next to each other. (00:10:28)
