This is a REALLY common problem with crap (ie. soft) oxide/binder. Top heads like to dig into the top surface.

Aufit -- http://info-coach.fr/atari/software/pc-projects/Aufit.php

HxC can also produce similar graphics but they are less awesome smile

yeah.. it's a shame when tools like this aren't open source

HxC being open source was VERY useful as I was able to hack the code in order to extract working images (ignoring sector sizes) from the .raw dumps of the Magnet System games for example.

(I couldn't see a way to force such behaviour from the command-line or GUI at least)

definitely limits how useful the tools are if you don't have the code to play with.

Yes, there are some marks on the surface. There are disks in much worse condition, don't know yet if they are interesting or not.

I'm trying to make SAMdisk accept those flux images and dump track data for MAME (and other emulators) to read. Controller simulation is WIP too:

OK, that's now working. Getting MAME to read them natively may be harder.
Code:
% samdisk --mx --scale=115 scan work/floppies/A3-05.scp
[work/floppies/A3-05.scp]
80 Cyls 2 Heads:
250Kbps mx, 11 sectors,  256 bytes/sector:
  0.0  0 1 2 3 4 5 6 7 8 9 10
  1.0  0 1 2 3 4 5 6 7 8 9 10
  2.0  0 1 2 3 4 5 6 7 8 9 10
  3.0  0 1 2 3 4 5 6 7 8 9 10
  4.0  0 1 2 3 4 5 6 7 8 9 10
<...>


Will clean up and submit to its github repo soon.

Shattered, did you checkout the "Palestra", apparently a Russian discrete ball & paddles game, full schematics in this blog entry:
Emulation of AY-3-8500-1 (and clones) soon ?? which also indicates that we had/have a decap going for the AY-3-8500-1,
which is the chip I was looking for. Anyway the Palestra could be a perfect candidate for you to try out Netlists as it is all in Russian I thought :-)

I heard of that console; never played it, though.

I'll put that on my backlog of cool hardware to emulate someday smile

Here's another cool hardware -- a sound card for Agat-9 (apple II clone/derivative):
