Definition

The Atari Jaguar CD Interactive Multimedia System is an attachable CD drive for the Atari Jaguar console. Games were distributed on Multisession Audio CDs that the console decoded as data. It had a rather limited library of official titles but has a fairly large homebrew scene.

General Notes

• Discs are treated like normal multisession CDs for the purpose of dumping. And are added without Universal hash.

Multisession range

Note: Redumper should do this automatically now.

How to calculate multisession range

• Open disc.txt in logs and go to TOC
• Session 1 range is LBA 0 to (last sector in session 1 minus 11400)
• Session 2 range is (first sector in session 2 to last sector of disc)

Example:

Audio Track  1, LBA        0 -    14887, Length    14888
Audio Track  2, LBA    14888 -    15484, Length      597
Audio Track  3, LBA    15485 -   226234, Length   210750
Audio Track  4, LBA   226235 -   226831, Length      597
Audio Track  5, LBA   226832 -   227278, Length      447

Session 1: 0-3487 -> (14887-11400)
