Currently, Nintendo Switch Online offers both the Nintendo Entertainment System along the Super Nintendo Entertainment System. A rumor on this service is that Nintendo will be adding both the Game Boy and Game Boy Color. It's only a rumor right now, but that has plenty of fans eager to see something else finally get added into the mix. Of course, both the Nintendo Entertainment System and Super Nintendo Entertainment System have notable omissions. Players have vented their frustrations over the lack of these classic video game titles. As a result, the Game Boy and Game Boy Color games might also lack video game content that is readily available for players. While we're still waiting on the official announcement of a Nintendo Direct, the past several years have seen a stream during September. Perhaps we'll see one this month which will also confirm the Game Boy and Game Boy Color games. Source
