I want to speedrun Smb 1 on emulator but ntsc is like super fast version of pal i can't find any solution to this can someone help?

it's normal that ntsc is faster than pal, that's how it is for older games

basically pal ran at 25 fps, while ntsc ran at 30 fps (50fps pal & 60fps ntsc for some consoles) ntsc speed is how the game is supposed to run
