I have the game Kao the Kangaroo from Go Sega Go on the top 66 list
There are 7 files in total with the extensions .001-.007 and the note in the .nfo file says "The game is MP3'd. So UNPACK/INJECT/Burn as usual for CDDA games"

The Specs are

Game.....: KAO The Kangaroo (C) Titus
Origin...: EUROPE - PAL/NTSC -
Filename.....: E-KAO.001
Released.: December 15th, 2000 - Format.......: DiscJuggler (CDI)
Platform.: Sega Dreamcast (DC) - CD(s)..... 1
CD1 Info.: 7 RARS / 80 MINS - Ripped.......: Nothing

Can anyone help - The above means nothing to me and I want to burn it.

Thanks
