TAS HD: Genesis Sonic the Hedgehog (any,r1) in 14:28.6 by Tee-N-Tee
Sonic bounces around surprisingly fast. The lack of Spin Dash makes the strategy a bit different from that of Sonic 2 and Sonic 3 & Knuckles runs, since preserving your momentum becomes a lot more important. However, this doesn't prevent the author from achieving crazy velocities even with such a significant limitation. In this run, the game is completed without collecting any emeralds.
This is the seventh run of this game, improving on the previous effort by 1:01.58 seconds with the use of new zips and improved precision.
To see a movie of this game that doesn't take advantage of zips, watch the "no zips" run by Aglar (http://tasvideos.org/1937M.html).
