Can you transfer Pokemon from other emulators without Pkhex?

Is there a way to transfer pokemon from emulators like VBA - M to Citra without Pkhex?

nope… there isn’t any of doing so… every emulator has their own servers and none can’t be linked together…

Can Yuzu be linked with Citra?

nope… not for now… but may be in future… the multiplayer option is still missing in yuzu… it will take some times until it is implemented…
