Enhanced Start Line (LE-CODE replica) [Kazuki] - Kazuki - 03-16-2021
This code will fix the Start Line Bug and support Second KTPT like LE-CODE.It doesn't change anything on regular tracks.
Fishdom Island and MP9 Toad Road are good tracks for testing.
This code uses vector of 0x81683220~0x81683223. Make sure no other codes use that vector.
