So, for months now, I had been playing Pokémon Mystery Dungeon Explorers of Darkness on MelonDS on my tablet, and it had been going well until tonight. When I tried to play it tonight, the starters on the boot-up scenes had changed to Totodile and Cyndaquil. Before tonight, they were always Piplup and Chimchar. Not only that, but the audio of the game became super loud, to the point where it was just too loud for me, even at my tablet's minimum volume. Fortunately, my save file is still there, but I want to be able to hear the game without it being too loud. Does anyone have any ideas on how to make the game quiet again?
