Struggling with getting the trackball to work for SegaSonic? Trying to get Sonic to go down and right or up and left perfectly? The Trackball Input Formula can help you!
Since my markers did not transfer to the BK2, here are markers for where the directions are in the movie:
Frame #40: Right - Frame #104: Up-Right - Frame #168: Up - Frame #232: Up-Left - Frame #296: Left - Frame #360: Down-Left - Frame #424: Down - Frame #488: Down-Right
This is intended to be used with the Japanese Rev. C ROM in BizHawk 2.9.1.
Shoutouts to rodonic01 for his first version of the formula! I refined his inputs so the Down-Right and Up-Left inputs will send you in the correct direction without deviating in a different direction because bizhawk is weird :v
