Key points

Updated version of Sonic CD, remade using the Retro Engine that features native widescreen resolutions, 60 FPS Special Stages, the ability to use the Spin Dash mechanics from Sonic CD or Sonic the Hedgehog 2, added Tails as an unlockable character, and includes both the North American and Japanese soundtracks.
Game physics and speed are tied around 60 FPS, meaning slowdowns on lower end machines and speedups with high refresh rate monitors.

Essential improvements[edit]

Decompilation port[edit]

An open-source decompilation of Sonic CD (2011). Requires the Data.rsdk file from the Steam version or extracted from the mobile version's APK to run, however, the former is recommended for better compatibility with unofficial fixes and mods.
Allows the game to be displayed with nearest-neighbor and pixel-perfect scaling, remappable keyboard and controller mapping editing via its settings.ini, native modding support, and full support of the updated scripts from the mobile version, allowing for features the official PC version never received.

Widescreen resolution[edit]

Use the decompilation port for unstretched scaling and support for aspect-ratios other than 5:3.
Glitches appear in aspect-ratios wider than 5:3 with the Steam scripts. Use the mobile scripts to alleviate the glitches with wider aspect-ratios.[citation needed]

Pixel-perfect scaling[edit]

The game's graphics in this re-release appear rather blurry, regardless of resolution selected and the in-game Nostalgia video filter does not provide a clear nearest-neighbor image. Use the decompilation port for native Nearest-neighbor/pixel-perfect support, or follow this guide by TheA_Gamer554 for a workaround to make the vanilla game run in a pixel-perfect scaled image; pre-made 4:3 and 15:9 setup.dat files are available to download.[1]

Mods[edit]

Mods require the Mod loader for the Steam version; the decompilation port can load mods natively, however, mod folders may need to be renamed to work together with certain mods due to the lack of mod priority sorting.
  • Sonic CD original 4:3 videos - Replaces the stretched 16:9 videos with the original 4:3 versions, pillarboxed to 16:9. Also fixes the speed of the Ending version of Sonic Boom from the US soundtrack.
  • Sonic CD AI Upscaled and Regrained Videos - A mod similar to the above but videos has been upscaled to 1280x960 using Topaz Video Enhance AI neural network with artificial film grain applied to recreate the look of analogue 35mm/16mm anime scenes.
  • Restore Lyrics Japanese Songs HQ - Replaces the instrumental Opening and Ending songs[Note 3] used by the Japanese soundtrack with the versions with vocals, as found on the original Japanese and European Mega CD releases.[Note 2]
  • Non-Wavy Tidal Tempest Flowers - Changes the flowers in Tidal Tempest Zone to no longer look distorted and wavy when out of water.
  • Palmtree Panic Past Redbook Music Restoration - Replaces background music from the past version of Palmtree Panic with the Redbook CD Audio version found on the disc for a beta version of the game.
  • Fixed Decomp Menu - Fixes the menus and title screen graphic of the Steam RSDK when played in the decompilation port while adding functionality to unused menu options and restoring the game's achievements by using the Time Attack menu system as a base. This mod is built-in for Sonic CD Restored, the And Knuckles for Sonic CD Restored add-on, and Knuckles the Echidna in Sonic CD.
  • Sonic CD Restored - A mod that restores various elements from the Sega CD version back into the Star Engine port with some quality-of-life improves to the visuals, sound, and gameplay while remaining faithful to the game's original features. Separate versions for 4:3 and 16:9 resolutions are available for the Steam version and decompilation port. Requires the Sonic CD Mod Loader if using the mod on the Steam version. This mod also comes with the Enhanced Hybrid OST and Purist Hybrid OST to replace the default Japanese and US soundtracks respectively.
  • CheatFreak's SCD Restored Tweaks - Adds extensive options for Sonic CD Restored, such as toggles for Time Travel Overhauled, the original Sega CD sound effects, the Sega CD version's extended camera, among other additional settings. It also includes some additional bugfixes while fixing physics inaccuracies and behavioral issues for the base game and the required mods.
