So I've been running SM64 for about a year, and I just made a Speedrun.com account, but I use Wii U Virtual Console to run. I don't have a capture card, and I use a Mac. How can I provide video evidence?

Point a webcam, your phone or something like that at the TV and make sure it’s in watchable quality.

Other than that, without a capture card there unfortunately isn’t a way to record a video of the run.

What @Timmiluvs said

but man I hate to be that guy, but why do all the "I have no way to record" guys have similar screen names?
