Cheat mode:
The following cheats rely on the infrared connection/communication feature. You will need two Tamagotchis. Refer to them as Tama1 and the other Tama2. Both Tamagotchis must be at least two days old to use the infrared connection. You can give or receive presents, play pop the balloon, or play an eating contest when you use the infrared connection. What the two Tamagotchis do depends on what order you select the Connection/Communication button (the heart symbol at top right hand corner of the Tamagotchi screen) and proceed.
For a Tamagotchi to receive a present, Tama1 and Tama2 both need to select the heart at the same time. Then, either Tama1 or Tama2 (the one that will receive the present) must press B at the "stand by" screen.
To have a food eating contest, Tama1 must select the heart, then Tama2 must select the heart, then Tama1 must press B button at the "stand by" screen.
To have a balloon popping contest, Tama1 and Tama2 both need to select the heart at the same time. Then Tama1 and Tama2 both must press B button at the "stand by" screen at the same time.
