Probably Super Mario Bros 1
i dont even really know. I beat the elite 4 on Pokmon blue at a pretty young age. But I didnt catch the original 150 so Im not sure if that counts
As someone who got all 151 (got mew through GameShark rest was legit) I would say getting all 150 wasn't required to say you beat the gameYeah, this. Beating the champion is completing the game. Catching every Pokemon is a 100% completion thing.
Battletoads for the NES.
