TAS Console Verification: Genesis Sonic the Hedgehog in 14:25.23 by Tee-N-Tee
This is a tool-assisted speedrun played back on the real hardware using a microcontroller connected to console's controller port. Enable annotations to get some description of my setup at the start of the video.
For more information about this speedrun, see http://tasvideos.org/4348S.html . Also see https://www.youtube.com/watch?v=xljyX... for this TAS being played back on an emulator.
