Subtle form of marketing
Despite advertising itself as a "free" emulator, the truth is that in order to use the emulator, you need to use a specific controller (Gamesir X2 or X3) and supports touch controls but they can only be used by paying a monthly VIP membership . And, it is known that NXTeam is working with the company who designs these controls.
Egg NS asks you to register an account with a real email address before playing - this is already quite concerning since it's unknown where that data is actually going, Egg NS have not given out any information about the server handling that information. Don't use your main email address.
Like DamonPS2, it's been sufficiently demonstrated that Egg NS has stolen code from yuzu and Skyline, without their permission of course. Egg NS shares several very specific problems in games with yuzu. And if you manage to start Egg NS without an account, the default account name will be 'yuzu'.
Unlike Skyline, Egg NS needs a monster of a phone to match the requirements, and even with them, 3D games are very slow.
Usage of unnecessary resources
Egg NS uses unnecessary resources and also is known to heat up your device quicker than Skyline. Also, this equals the emulator running games much slower than Skyline especially with Cuphead, and crashing.
