Hi am new and I started speed running because it looks' fun but I wanna speedrun super Mario bros 1985 but I don't have a nes or the speedrun timer, I have to play on a flash website to play the game, does it count or do you need the original game? also I cant download a timer so what do I do,

Am asking this is because I've been practicing and I don't want my run to be rejected because I don't have the original game
