TAS Genesis Sonic Spinball 100% by Flip in 13:

This is a tool-assisted speedrun. For more information, see TAS originally published on 2013-01-09. The evil doctor Robotnik has a new plan to take over the world. He has built a new weapon, the Veg-O-Fortress on Mount Mobius and with it, he is transforming all creatures into robots. Sonic sneaks into the fortress and tries to stop Robotnik. This run aims to complete all levels in the game, which includes the optional intermediate levels, and the now featured Multiball levels. These only appear after collecting all rings on the map, thus those need to be gotten too.
