Howdy!
In this video I showcase online Local Play in Mario Tennis Aces on the Switch emulator Ryujinx. The build I'm using is the LDN2.2 build which emulates a local wireless connection which allows you to connect to people around the world through local play options. Note this is not the same as Nintendo Switch's Online service you can't connect to official Nintendo servers. Also, for the best experience, build up your shader cache by playing against CPUs before playing online to prevent frequent disconnects.
