I debugged my tamagotchi connection a few days ago, I screwed it back together and put it away to fix later after I accidentally detached the speaker wires. This glitch kept happening, even after multiple resets:
I put the battery in, then it makes the normal beep noise and shows the egg bouncing at normal speed.
I press B and the clock screen shows up and it's making me set it.
I set the time, date and birthday to random numbers.
It goes back to the egg like normal.
I wait a few minutes and it hasn't hatched.
I press B and it's asking me to set the clock again, but it has the numbers I input last time.
Repeat X infinity including resets and taking the battery out.
Any advice on how to fix it would be great. I did debug it and un-debug it 2 or 3 times in hope of fixing it. I also tried coloring and erasing the J1 and J2 buttons too, but I don't think that would have done anything anyway.
