Sega Classics Arcade Collection Sega CD / MegA CD

Released in 1992, the 4-in-1 version of Sega Classics was sold with the Sega Multi-Mega/CDX, and retailed at $59.99. In some instances it was also bundled with the Sega CD version of Sherlock Holmes: Consulting Detective and with the Sega CD itself.

Games:

Columns (1990)
Golden Axe (1989)
The Revenge of Shinobi (1989)
Streets of Rage (1991)
The version of Revenge of Shinobi included in this collection is software revision 1.02, including only the Spider-Man boss-fight, with Godzilla and Batman replaced with substitute enemies.

Golden Axe is the only game in the collection that has external CD audio (aside from Columns but only the title screen track uses CD audio) and it uses the arcade version's soundtrack. However, it is heavily based on the Mega Drive port with the voices changed to higher quality voices (none of them, besides the townspeople screaming in Turtle Village, are from the Genesis or Arcade version).

In the Japanese version, Streets of Rage goes by its western name rather than its Japanese name Bare Knuckle. Streets of Rage is generally the same as the Genesis version aside from the voices, which are CD quality enhanced.
