I have the mine version of the snes that contains super mario kart a game i loved from a young age can I use that to submit runs?. If so would I have to submit them as emulator or console since it's kinda both in a way.

it doesn't matter which snes you have. the only think that's important is that you had the original game. How i said you can play it on emulator, snes classic, snes mini, wiivc. Your had no problem playing with your snes to speedrun SMK.
