Trivia

 * Virus Buster in its original form was designed to help players relax instead of training their brains in Brain Age 2. It even includes relaxing arrangements of the classic Dr. Mario music.
 * In the Virus Buster game, if the player presses while their cursor is on a Mii while in game, it will say something such as, "Good luck, Dr. Mario!" or "The more bitter the medicine, the better!" Sometimes, the Miis will tell the player information concerning the actual gameplay, such as how many minutes have passed and how many capsules they've thrown. If the player presses  while their cursor is on a Virus, it smiles to the front.
