Here's what I've found, the list is in chronological order starting with the earliest:
The Sound Barrier: Too old
Composer 669: N/A
RQ Demo 0: Not checked, screenshot suggests music is a ripped .mod
Black Glass: Uses an early incompatible version of CDFM
Yet Another Renaissance Demo: Uses same early version of CDFM
Black Glass 2: Two CDFM songs, included in link below
Amnesia Music Player: N/A
Amnesia: Files already posted
Renaissance 93: No music
Daretro: One SB CDFM song, included below. Also has a GUS song but the samples aren't stored with it like in Zone 66. Maybe it shares the SB samples? The length fields for each sample are certainly similar.
Muzik File: Three SB CDFM songs, included below. (I recognise some of the samples in these songs from the Zone 66 music)
DoWhackaDo (with SPD): .exe is compressed, can't find any songs in DOSBox memory dump
Multitracker Module Editor: N/A
nothing on: Music files seem to be in a variant of .mtm, ModPlug accepts them but doesn't play them properly
Epidemic (with iCE): Music files are all .s3m, any ripper can extract these
Here are the original CDFM songs plus conversions to S3M:
renaissance-cdfm.zipIf anyone is interested I have starting writing a ripping utility as I couldn't find a good one that works under Linux, and I miss the old "Ripper 5" from my DOS days. It's nowhere near as functional as Ripper 5 was, however it does support ripping CDFM files :-) In a homage to Ripper 5, I have called it Ripper6 and
the code is up on github.
