Last year, Nintendo launched the Switch Online Expansion Pack, which added Nintendo 64 and Sega Genesis games to the service’s library of classic games. Now, some new evidence has surfaced suggesting that more classic Nintendo systems could be joining in very soon.

As shared by @trashbandatcoot on Twitter, files for Game Boy and Game Boy Advance emulators for the Switch have allegedly leaked via 4chan. These apps are codenamed “Sloop” and “Hiyoko”, and seem to have been developed by Nintendo Europe Research & Development (NERD), who worked on the previous emulators used by the system.

So Nintendo's official Game Boy Advance emulator for the Nintendo Switch just leaked. Now it's just a matter of waiting for NSO to add GBA. pic.twitter.com/mEJcKrRtzL

…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

The files also included a set of Game Boy and Game Boy Advance titles for the app, although not all of them are playable.

And even though there is a Game Boy emulator, only 4 playable games were found: Super Mario Land, The Legend of Zelda: Link's Awakening, Qix and Tetris.

Of course, until Nintendo actually announces such a service, we caution readers to take this discovery with a grain of salt. We will be sure to report back with more details as they come.
