The 2011 release of Sonic the Hedgehog CD is an enhanced downloadable remake of the 1993 Sega Mega CD game Sonic the Hedgehog CD. It was developed by The Taxman using a proprietary game engine named the "Retro Engine", an updated version of the engine used in Retro Sonic Nexus. His efforts were picked up by Sega who published it for Xbox Live Arcade, PlayStation Network, iOS and Android devices and PC in late 2011 and early 2012.

Unlike other attempts at bringing classic Sonic games to new platforms in the late 2000s (usually handled by Backbone Entertainment), this Sonic CD is neither a port of the original game nor an emulated version. It was re-built from scratch, allowing for a number of enhancements such as widescreen support, online features (such as leaderboards), filters to change the way the game is displayed and a Sonic the Hedgehog 2-styled spindash option. When the game is beaten once, Tails is unlocked. It is otherwise faithful to the original game.

Other changes include reduced loading times, better scaling for the UFOs in the Special Stages, a number of bugfixes and a constant framerate of 60FPS.

Music

The original Sonic CD had its soundtrack changed for the North American release, leading to two distinct soundtracks for the game. This 2011 version includes both, and the user can toggle between the two. Undisclosed licensing issues mean some vocals from the Japanese soundtrack have been removed. All stage music tracks have been edited so that they loop. Some songs from the US track have been extended somewhat, using cues from the Sonic Boom album.

Other Differences

• Sound effects have been added to the pinball flippers at Collision Chaos.
• At Tidal Tempest, there's a chime before the underwater countdown begins (much like the Genesis/Megadrive titles).
• The level select menu and sound test can no longer be accessed by code. Instead, they have to be unlocked in the same manner as the D.A. Garden and Visual Mode.
• While the debug mode is enabled, power-up monitors can be used more than once.
  • Ring objects are now available to be placed, unlike the original.
  • There is no background music that plays after the "S" monitor has been struck.
• During the final battle against Dr. Robotnik at Metallic Madness Act 3, two "light beams" have been added to each side, which are akin to the ones at the Final Zone, Wing Fortress Zone, and Flying Battery Zone.
• When the Japanese soundtrack is enabled, there is an entirely new song that plays in the Time Attack menu.
• During the Metal Sonic race at Stardust Speedway, the Bad Future theme always plays in the background, regardless of which soundtrack is chosen.

Known Bugs

• When the Sonic CD Spin Dash is enabled, there is a delay in speed after striking the Speed Shoes monitor.
