The Old-Manmon - I have been sent a message from someone that says when your Digimon is 30 years old and reset it continously for 5 mins non-stop (pull the tab in and out), you will get an "old man mon" . He is better than the skull shooting teddymon and he can turn the opponent into a butterfly with a cheat. He can easily kill a rookie and would be very hard to get poisioned even with the poison code. His life is quite short though.This code WILL work! It was tested by 7 people.
WARNING I AM NOT RESPONDSABLE FOR WHAT HAPPENS TO YOUR DIGIMON!
Akumamon - Insert the tab and press A five times, C 2 times and B 10 times.
Computermon --when your teddymon dies press "c" 10 times while holding "b" then reset it and you should have a computermon.
