Hi! I want to speedrun Mario Galaxy 2 Any%, but i don't want to record the gameplay. I'm also new to speedrunning so some help would be very nice. I also don't know how to submit speedrun gameplay from a Wii, so please lend me a hand. I just want to try speedrunning for fun, but i'm serious about doing it. Thanks!!!
If you want to submit times to the Mario Galaxy 2 Board, you need to record your runs as video proof is necessary for that board (and for most boards in this site). You can record using a camera, webcam or a capture card, anything as long as your video is clearly visible. It doesn't need to be amazing quality, just recognizable enough.
With that said, nothing stops you from speedrunning without recording, in fact many people do that and have as much fun. Whoever you won't be able to submit any personal records to the board like this. This is up to you.
If you want tips with Mario Galaxy 2 in specific you are better off asking in that game's respective forum and community. Good luck!
