The GBA (Game Boy Advance) is a handheld game launched by Nintendo in 2001, which has released many classic games. Recently, it was reported that Nintendo will launch an official GBA emulator to let Switch users play GBA classic games!

Some data has been unearthed in the Switch development kit, which shows that Nintendo Europe Research and Development (NERD) is developing a GBA simulator called "Sloop", possibly built for Switch Online. The breaking data also includes some specific screens of the game's simulation operation. There is also a GB emulator called "Hiyoko".
In addition, some of the GBA game lists that have passed the simulation test have also been exposed, including Castlevania, Fire Emblem, Ranch Story, Star Kirby, Kingdom Hearts, Mario Kart, Mario Party, Mega Man and other famous games.
In fact, after Nintendo launched the Nintendo Switch Online (NSO) service, simulating classic games such as GBA and GBC has become a matter of course, but at present, Nintendo has not officially announced the relevant news.
