Do you mean titles without any copy of original (missing dump) or bad dump? If so, do you have some examples?
Thanks.


Both. At Atarimania is well visible is there STX, or in rares cases some ST/MSA image of original. I think that %-age of missing is pretty high, some 15% . There are certainly still some bad dumps, at some of them there is note about error and appeal to send good image.
Examples: missing dump: Uridium
Bad dump: can't remember at moment any
But there are some releases with errors too: http://www.atarimania.com/game-missing- ... 15997.html
http://www.atarimania.com/game-atari-st ... 10517.html

Indeed, Atarimania is currently site most active in supporting preservation by hosting images, SW database and related.
They want STX images as I know. Not sure will host some SCP or KryoFlux. Conversion is good in most cases.

public domain series, cover disks: http://downloads.atari-home.de/Public_Domain/

More folders besides PD to come (FTP servers backup (about 365.000 files), demo scene (65GB), ... but no commercial games/software due to risk)

Forgive any ignorance on my part, but isn't STX only for emulators, as in it can't be written back to disk?
It seems it can image protected disks for use in an emulator which is great and therefore it has a purpose.
But other disks, not protected, shouldn't be saved in STX as it unnecessarily adds a limitation in where it can be used, for no real benefit.

An unprotected disk should be saved in something like .ST (?) format and a protected disk should be ripped using either STX or Kryoflux, perhaps the latter, as it means disks floppies can be written back via the Kryoflux as far a sI know (fairly recent update I think?).
I have a Kryoflux now and will play with it when I get time.

But I intend to save/provide Atari disks in formats than can be written back to floppy, there is no reason those images can't also be used by an emulator so no-one should be unhappy.

Ijor can say more about: but it is not strictly for emulators. Writing of most images is possible, but it needs more work on. What may not be needed, as count of flux images raises. However, you need to know that STX images can be made with regular Atari ST and it's floppy drive, and that imaging of popular SW started over 10 years ago. So, number of such images is pretty much big. Basically, over 80% of all Atari SW is covered.
If some release is not copyprotected, you can easily convert STX image to ST. I have SW for that.

I think that count of people using emulators instead real HW is bigger, and it will be just more by time. Of course, with newer devices like KryoFlux or SCP you can do writable images, more accurate ones, so just enjoy it. And if possible share them. Situation is that count of those forensic images is much-much lower than of STX images. I would by myself one, but I just don't have enough floppies to image. Nothing rare, all is already images in STX, there is couple what is not yet images with Kryo or SCP. I had some mailing with Istvan about they borrowing me Kryoflux for couple weeks, but then whole mailing stopped.

Another problem at moment, as I see is about repository where can host those forensic images. SPS (Kryoflux) has some special policy, what I don't want to discuss here. Unfortunately, some still talk and maybe try to enforce some really useless and outdated laws, while floppies have no mercy - they just degrade, and if we do not preserve them soon (one way or another), some titles will be lost forever.

How do you convert non protected STX to ST?

I only recently bought my Kryoflux as I was waiting for the ability to write the images to disk with it without having to go through SPS.
I don't really agree with a lot of their policies in terms of them being gatekeepers. Single point of failure = bad.
I'll be putting whatever I image on my own servers and anywhere else I please.
The wider something is distributed the more chance it stands of survival.

Here is program, Windows SW:
PastiCS.zip


I made it for my needs, there are options what you will not use most likely.
First click on Create info file and select STX image. That's necessary to get info about floppy geometry - how many sectors/track, count of sides, tracks. Will get txt file with same name as STX, open it with Notepad, and will see. Regular floppies have 9 or 10 sectors/track, 80 tracks, 1 or 2 sides. Automatic detection of parameters is hardly possible, because even unprotected floppies have often for instance 10 sect/track physically, but only 9 of it is used, so you need to type there 9 instead 10 if resulted ST image works not, shows not files ..
Some floppies are actually only 1 sided, but there is something on side B, and Pasti imaging all for case - maybe there is protection or whatever.
Then you need to check on A instead both. Then, may extract only side B as ST image - that is useful in some special cases.
There are other options, but I will not describe them. For conversion to ST is enough what I said. Just to add that DrCoolZic adding, or added same thing what is here called Shrink STX - dropping track dumps which are not used by protection.
