Ever since Switch Online was launched three years ago, Nintendo has slowly but fairly steady expanded the selection of included retro games. Unfortunately, many of the biggest titles from NES and Super Nintendo are still missing and the selection has been quite lackluster lately.
But it seems like Nintendo has realised this. According to the podcast Nate the Hate, run by the insider NateDrake, Nintendo is currently about to add support for both Game Boy and Game Boy Color titles to Switch Online. This will arrive within a few weeks, although NateDrake says we should not expect Game Boy Advance for a long time as Nintendo wants to do re-releases of its greatest hits first.
The Nintendo fansite Nintendo Life claims to have sources saying Game Boy and Color support is coming for Switch Online as well, and they are usually fairly trustworthy.
Let's keep our fingers crossed that this is true, and maybe we'll be able to play games like Super Mario Land 2: 6 Golden Coins, Teenage Mutant Ninja Turtles: Fall of the Foot Clan, Gargoyle's Quest, and of course, the best version of Tetris ever made.
