Looks like someone else discovered that you can run PAL SMB1 at NTSC speed. This isn't allowed, by the way. EDIT: Also saw the ROM link in the video description, so I've removed the video.
I removed the rom link from the video. however I started the rom normally with fceux and created the tas, I don't know why it makes me so fast! so if it does not count as a tas it is better if I start another one, but with the right settings
