Requesting help to search for 2 lost mobile games of the Mystery Dungeon Shiren the Wanderer series: Everyone's Mystery Dungeon (package name: jp.mbga.g12009000.mktapp) and Rainbow Labyrinth (jp.co.chunsoft.ShirenRainbow) released roughly 15 years ago.
There is barely any information about these games besides promo images and in Everyone's Dungeon case a NicoNico video (sadly the person who made that video deleted the game 3 years ago)
Any small bit of new info is appreciated.
