How do you get platinum rank in mystery dungeon Explorers of Time?

Answer 1

do missions like theres no tommorrow! I'm on hyper rank. and secret rank. to get secret rank, there should be a mr mime next to the keckleonn shop (only if you finished mystifying forest) will say something about blizzard island and sizor. you willl have acsess to it finish it, then crevice cave , i forget the legendary pokemons name. but defeat it the sizcor is rescued and you have secret rank. i know the secret rank is not the answer but i already said to do alot of missions. so do the ones with the star and a number next to them. they score higher than letters!
