im sure if you searched tamatalk or looked in something like Tips and Tricks, there would be a topic on debugging tamas (some with very detailed diagrams too!).
BE CAREFUL. it just might RUIN your tama. and you wont be able to use it anymore. i HAVENT tried it.
its best that you research "tamagotchi debugging"
use a search engine and find the best sites.
if you want i would help you...
what version would you like to debug?
