有传任天堂计划将Game Boy游戏加入Nintendo Switch Online中，开放给已订阅的玩家。而网上也有流传游戏的截屏，令可信性大增，惟任天堂没有回应有关传言。
据Neowin报道，Twitter用户Trash_Bandatcoot（@trashbandatcoot）指从泄露文件中可见，主要负责开发任天堂官方模拟器的欧洲研发团队NERD，正开发代号为“Sloop”的Game Boy Advance模拟器及“Hiyoko”的Game Boy模拟器，称任天堂正开发于Switch Online的Game Boy、Game Boy Color及Game Boy Advance的模拟器。
…called Sloop, and the 7z archive is called Hiyoko, which is a Game Boy emulator, with all Game Boy games being separate applications. These emulators are developed by NERD (Nintendo Europe Research & Development), and are both functional, albeit with a few bugs. (2/?)pic.twitter.com/RRUAVvz2BX

此外，Trash_Bandatcoot更称Switch上的Game Boy游戏皆为单独的应用程序，并附上于Switch主机打开Game Boy Advance模拟器的视频，但发布后随即被删除。
不过任天堂没有回应有关在Switch Online上开放Game Boy和Game Boy Advanced模拟器的传闻。
