wow your good! my sister got to generation 16 once but the battery died and it reset and she couldn't get it back! I usually end up leaving it at home unpaused by accident and it dies. but I'm at generation 2.
There's no way that your Tamagotchi screen actually says 100th generation. You may very well be on the 100th generation but the Tamagotchi only counts up to 99. Congrats on being a great care giver! I barely have the patience for 1 generation now.
I am not that lucky. I lost my 1st tama at the zoo about 4 years ago. Since then I have never been able to keep more than 3 gen. of tamas, but I hope to break the "curse" with my new v5.
The farthest generation I made to was the 5th. Oopsy. I'm not a very good tamagotchi caretaker. I tried though. I've just been busy. Congratulations!!!!!
