Well I wouldn't try debugging your tamagotchi can break. But there are smaller screws on the thing when you take of the top to tamagotchi cause there is a cover over top the debug thing, so try to unscrew those with a smaller screwdriver then it will show.
Well you can get your tamagotchis married or have the matchmaker come and see you when you are about 7 or 8 yrs. old. ?I have had that happen to me before donate some more points and then you will get a password.
Yes I am very afraid I will break my tamagotchi if I try debugging them, so I have never tried. Debugging is kinda wrong too you shouldn't just start messing with a electronic virtual pet toy, it's not right!
