You might remember Tamagotchi virtual pets from the 1990’s. These toys are still around and just as demanding as ever! This talk covers my latest efforts at hacking Tamagotchis. First, I will detail methods for executing code on and dumping code from a Tamagotchi, and then delve into the deep secrets of Tamagotchi life that only code can tell. Finally, I will describe the internals of the Tamagotchi’s GeneralPlus microcontroller and demonstrate some projects that can be built using a modified Tamagotchi.
