Sonic CD Restored is a unique remaster of Sonic CD made for speedrunners by one of the first Sonic CD speedrunners; it restores all the glitchless speedrun routes from CD93 to CD11 while retaining CD11's routes as well. It restores all the missing stage sprites, palette cycles, fixes all known bugs and restores full fidelity to the BGM/SFX/FMVs. CD-R adds Amy as a playable character, Special Stage Rush, Crowd Control, a Randomizer, and implements Naoto Oshima's originally intended instant/no-load Time Warps based on his sketches, interviews, and early development screenshots.

On 9-23-24 for Sonic CD's 31st birthday, Epoli released a version 5.0 R5 of CD-R
