Could it be possible to develop a PokeMMO based on citra and yuzu?

I am a PokeMMO player and I am also studying a video game development technician and I would like to know if it would be possible to create an mmo pokemon with all the games from the sixth generation to the ninth using the citra and yuzu base.

I think yes, but i’m not sure. If yes, then u’ll have to deeply understand the working of Citra and Yuzu AND look for servers for the multiplayer functions

I have no idea what you mean by “using the citra and yuzu base”. Citra and yuzu are emulators, not game engines. We emulate a console’s functionality to run its games.
