Atari Jaguar CD

[6] In mid-1994 Atari and Sigma Designs signed an agreement to co-develop a PC board that would allow Jaguar CD games to be played on home computers, with a scheduled release by the end of 1994.

[8] The Memory Track cartridge stores saved game position and high scores.

[9][10][11][12] The Jaguar CD has a double-speed (2×) drive[13] and built-in VLM (Virtual Light Machine) software by Jeff Minter, using a spectrum analyzer for a sophisticated video light show for audio CDs.

[8] It is bundled with Blue Lightning, Vid Grid, the Tempest 2000 soundtrack CD, and a Myst demo disc.

It allows for more storage, and its incompatibility foils casual piracy, at the expense of reduced error correction.
