Sonic CD Restored 30th Anniversary Edition

Version 5.0
Winner of two SHC Community Trophies:

Crowd Control and Randomizer were both added in the build up to SHC, though they don't work with Knuckles yet.
Knuckles has been fully implemented in Version 5.0 after an open beta event I called Retro '93 that started on November 23rd 2023.

Sonic CD Restored is a mod that restores lost Sega CD features and glitchless speedrun routes back to the game and polishes the video/audio/gameplay by restoring fidelity, fixing bugs, and providing small quality of life improvements.

In effect, this combines the best gameplay from CD93, the best gameplay from CD11, the best gameplay from Origins and the ability to cherry pick between JP and US tracks for the player to make their own unified experience for the ultimate rush of high level speedplay in the best Sonic game of all time.

-Restored Sega CD MM3 ramp jump (Thanks to InceptionKitten)
-Restored Sega CD MM3 Lightning Bugs hurtbox appearing 1 frame before its hitbox

-Restored Sega CD MM3 piston hitbox so you have exactly 1 pixel of space to land to its left instead of falling to your death over and over ;p (this doesn't help with speedrunning, it just helps casual players)
