Tamagotchi Cheats

With an Adult Tamagotchi, win ANY tournament. You will get a symbol above your tamagotchi's picture on it's stats screen. Now, go to the options menu. There will be a mode called MUSIC MODE. Inside are:

Sound Test
Sound FX test
Sound Test Speed
A gallery of ALL the characters you get after that Tamagotchi wins. They are numbered and you have to get all of them to beat the entire game.

If you enter the status window, your pet cannot die. This means that a couple of cheats are available. 1) If your pet dies, restarting the game and quickly entering the window before it dies again means that, if you exit the window a bit later, your pet is healthy and ready to carry on as normal, or 2) You can have a tamagotchi live forever. You need a Game Boy adaptor for this to work. Go to the status window, and leave your game boy plugged into the wall for as long as you want.
