I’m not sure but maybe you could ask the discord server or one of the mods and they could probably help

just record a video with your phone or something, its probably less complicated then trying to submit an src run through livesplit

I cannot confirm or deny if submitting runs through LiveSplit works, but there are alternatives for recording your run. submitting your videos with Google Drive would be a valid thing to do. It seems that you used that method for your Wii Play speedruns and it worked out. Recording your screen with a phone and having your LiveSplit timer on the side works too.
