Xyphoes Fantasy (http://www.youtube.com/watch?v=Pe3RfKKhokM) has a digitised tune in it's intro and outro parts, made on an Atari ST tracker called TCB Tracker (http://home.earthlink.net/%7Echhome/tcbtracker.html). Is anyone aware of any other CPC games that use this music format? Thanks :)
I think Prehitoric II also uses the same technique for its intro music, and Megablasters. Don't know for sure though. I've never played Fluff, but try that one also.
Crazy Cars 2 (normal CPC version, not the GX4000 release)
I don't think its hard to do but doesn't sound very good at all, I'm sure I remember either an Amstrad Action covertape program or type-in where you could record the sound from the tape drive and store it as a file to call - I think I did an Iron Maiden song or Slayer's 'Angel Of Death' and it sounded bloody awful!
Prehistorik 2 I think is using the Plus's DMA chip and is sending digitised tracks through each of the channels like layers, which is a little different and soudns better to recording the whole track and playing at once.
Oh and Le Manoir de Mortevielle has digitised music :)
Well, it sounds 'awful' now, but back then it sounded bloody cool!
