In the Dreamcast version, while General Bristol is teaching you about health, you can still switch weapons and shoot while he is talking. If you happen to be shooting when Sergeant Sternhauser kicks you, sometimes you will fly very high into the air, and when you come back down, you take considerably more damage than the usual 25 damage.
While playing the Dreamcast version, if you attempt to scroll through the dialog that Sternhauser says to Bungalow about his jumping abilities, sometimes the game will hang, and force you to restart the system to get out of it.
Juliette can access an unused area in the Dreamcast version. Once she's down there though, she can't get out.
