The timing difference makes RTA record seem shorter than TAS record, but still, it's close enough.

TAS saves time in 1-2, 4-2, 8-1, 8-2, 8-3, and 8-4, using faster acceleration, going through the wall, flagpole glitch, etc.

TAS is NOT programming.

None of the two runs uses "cheats" of any kind. If you have questions, watch darbian's tutorial:    • [Tutorial] Super Mario Bros. any%
