The audio system for my Wii is kinda messed up, so is it ok for my video proofs for my runs to exclude game audio, or should I get it fixed first?

You don’t need game audio afaik, but I personally prefer it. I’ve seen people run with music instead of game audio so I’m guessing you’re good. You should eventually get it fixed though.

Having no audio is a run makes it way eaiser to splice/cheat. I of course know that its just a problem with your wii but my point is that you can't be 100% sure a run is legit if i dosn't have audio. So like DCA said you should probably get it fixed at some point
