Nearly a year after apparently-Nintendo-developed Game Boy and Game Boy Advance emulators for the Switch leaked online, Nintendo has finally made those emulators available to Switch Online subscribers. All subscribers can download the Game Boy emulator, which includes a combination of classic Game Boy and Game Boy Color games. Game Boy Advance emulation, like Nintendo 64 and Sega Genesis emulation, is exclusive to the more expensive "expansion pack" tier of the service.

Nintendo's first-party emulation efforts don't have an amazing reputation, and the N64 emulation, in particular, has suffered from accuracy issues and other bugs in the past (though Nintendo has addressed many of the problems that existed at launch). But the emulators for older and less-taxing-to-emulate 2D systems have generally been pretty good, and both Game Boy emulators fall into that group.

The user interfaces for both apps will be familiar to you if you've used any of these other first-party emulation apps on the Switch: a screen full of games (not very full at this point; per usual, the selection is limited at launch and will slowly expand over time) in a customizable grid. Zip over to the menu on the left to switch between single-player and offline and online multiplayer modes. But it's the Settings menu that we're most interested in.
