Thanks, though I would double check how your saves were transferred as the Big Snake Game Over should still be in the game.
Is the scene not appearing? An error message? Skips it entirely? Does it appear in the Gallery at all?
Beat the first boss, trigger the cutscene above them, then use the Key Item, Ankhrono Replica, to access Somewhere Between Time and Space where the gallery is the room to the left.
There is also a walkthrough if you have more questions.
