Super Mario Bros. TAS vs. RTA former World Record (4:56.878 by darbian)

Update with new WR (4:55.913): https://youtu.be/ZZ5GzGldoHI
Comparison video of the current world records of SMB.
TAS (Tool-Assisted Speedrun, human playing with emulator assistance, not in real time) WR: https://youtu.be/tdMHOXRX08o
RTA (Real Time Attack, human playing in real-time) WR: https://www.youtube.com/watch?v=j8CHs...

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: https://www.youtube.com/watch?v=PInZ2...
