Problems with cdi files that have an audio session followed by a data session

[Wayne]

You might also have a newer Dreamcast machine. Check the date on the bottom sticker. If it's OCTOBER 2000 or later, it won't work with the old-style backups.

If so, you'll have to extract the .CDI files to your hard drive and burn ISO files instead, then use BIN2BOOT - the newest one is the one to use: http://dcxeal.virtualave.net/b2b-cdda-b1.zip

You might also require a tutorial to help you along. Try this: http://dreamlover.tecbox.com/#6.1

Good luck.
