Fushigi no Dungeon - Fuurai no Shiren GB - Tsukikage Mura no Kaibutsu, translated as Mystery Dungeon - Shiren the Wanderer - The Monsters of Moonlight Village, is an entry in the Mystery Dungeon series of roguelike games. The game follows Shiren The Wanderer, and his talking weasel Koppa.
Rather than go on an adventure with Shiren, CasualPokePlayer instead abuses input handling programming errors to execute arbitrary code and jump straight to the credits roll, which lasts longer than the actual gameplay of this run.
