What(if any) should I use to capture my NES and n64 runs through my cell phone? I'm new here and and still trying to get set up. Any advise helps. Can I just record my run with my phone's camera? But there's no splits or anything. I dunno what I should do first.... Help?

Yes, you can use your phone’s camera. Splits shouldn’t be required. Just make sure to read the rules of the leaderboard before you try recording a run.
