Connecting to Melee - SSBDoppler/slippi-hud GitHub Wiki
Finally how are you connecting to melee?
In-Person
I recommend the console mirroring option the slippi desktop program provides.
Start the console mirror process. I heavily recommend using realtime mode, or else the HUD will get significantly ahead of the action. (which means hardlining your Wii and computer)
A good tutorial if you don't know how to do this can be found here
Select Console Relay in the dashboard and enter the port the slippi desktop app gives you.
You can also now just dropdown dolphin, connect, which will normalize the lag, but you'll probably add a couple frames vs the relay but you couldn't get super far ahead either, connecting this way also makes the input display less useful as it only reports analog stick inputs and not the buttons or triggers. There's pros and cons, find what works best for you.
