The emulator will only work when paired with a pair of Nintendo Switch-style remotes that clip onto either side of your Android phone. It all sounds a bit dodgy to me, and it gets worse.
You have to create an account to use it (which sounds like data mining to me) and the American team that claims to have been working on it have a website that is mainly written in Chinese. A source in the Android-modding world has found code that has been ripped straight from the Yuzu software and thumbed into this new Android friendly emulator.
This software violates the MIT open-software license. Sadly, 73 of those crash while playing or only make it to the in-game main menu. The emulator itself, which shall remain unnamed for reasons we’re about to come onto, boasts 81 playable titles. If your Android smartphone is old, then the chances are you’re not going to get the best performance. The emulator really needs to be run on devices equipped with the Qualcomm Snapdragon 855/855+/865/865+ flagship SoCs.
