I recently go into the modded nintendo switch scene and I am currently learning the in’s and out’s of everything. I have tried to look on google and YouTube about this I can’t find anything. I am currently trying to figure out where these roms/games are being stored inside the Nintendo classic app for gb, gbc, gba, and n64. I would like to delete and add games in here. Any help for a newbie would be great.
