I remember my camp day we had this big Game Boy, Game Gear, Lynx Fude over battery life. at the end of the weekend my Game Boy still had battery life. Lynx died 1st and the kid broke in to the Game Gear and swapped batteries so Game Gear would lose the contest. But the trick was obvious because of brands.
Just don’t accidently stop your parents from meeting, have your dad get a huge crush on you, invent skateboarding, alter your family’s living situation, impersonate your own children, give Dakota a book form the future, encounter your past self, get struck by lighting, sent to the old west, fall in love with a school teacher and get shot in the back over a matter of money or crash in to those Indians.
best off if you save the whales , pinch rude people, and save a woman’s kidneys and go home.
I would time travel o move my Pokémon to a compatible format and tell my self tha Game Boy will never be compatible again
