This is a tool-assisted speedrun. For more information, see http://tasvideos.org/3956M.html. TAS originally published on 2019-05-08.
Donkey Kong and Diddy Kong are on a quest to retrieve the former's banana horde from the Kremlings. But with less hurry than usual.
In this run, Tompa (http://tasvideos.org/Tompa.html) completes the game while avoiding the Y button that allows characters to run and to roll. Game mechanics such as grabbing a rope and getting shot out of a barrel are used to boost character speeds. See the author's comments (http://tasvideos.org/6352S.html) for details. Note: 5 presses of the Y button are required in one boss fight in order to pick up and throw barrels.
