Hi. I'm trying to extract music from one demo file (X-Files, The (1988-02-01)(SHP)(pl)[stereo]), all I get after extracting is 14 corrupted 1Kb files.

I tried to use ATADIM, makeATR, Altirra, etc- no luck...

Are there any chances to extract the sound files?

Thanks in advance for any help :)

P.S. The demo file itself- http://nitroroms.com...tereo].atr.html

Hmmm,

 

this looks like a bootdisk with no filesystem to me. Or the files are hidden somewhere.

Think MakeATR, Atadim and others will only extract files from a standard DOS 2.x filesystem.

From what I can see there is no DOS on this disk that would understand what a file is to begin with. So entries in the directory are using illegal file names with invalid directory flags and each 'file' is 4 sectors long only. I suspect the simulated VTOC, and directory sectors are just eye candy and this one needs to be disassmbled as a boot disk which has no files at all.

CharlieChaplin is right about most programs not being able to even mount this disk to extract any files.

Thanks for the info guys, after some trying found the music on Demozoo (http://demozoo.org/music/119914/) :)
