Re: D9090 back to life !

Talking of D9090 the AM2910's run code from 82S137s and they have never been dumped.
It would be pretty amazing to get those and be able to emulate that, rather than HLE’ing the SCSI drive.

Instead of me beating this particular dead horse, I'll turn around and beat the X64 horse awhile.


The X64 format has a field for "number of tracks".  Was this intended to allow partial disk images, e.g. Tracks 1 thru 18 of a D64, or did it serve some other purpose fantastic or mundane?

    uw. terrible idea imho. having all these d64 variants that can only be
    distinguished by their file size is terrible enough already.

  I prefer putting the info block on track 18, personally, which does not affect size. 





    and yeah, why not use x64? support for it is right there afterall :)

  I don't know why folks don't use it.  But, few do.

  I agree it's a more complete format, but it's not used as much.  My idea of putting this same information on track 18 would add this information to the image, and has the benefit that folks could "see" if the disk came from an image when they use a real disk.

  Yeah, I know it "corrupts" the image.  complaints to /dev/null
