One thing I'd like to clarify though - myself, Zarxx and other contributors to the preservation initiative have also contributed non-original (sometimes cracked) dumps to Atarimania. You will most likely be seeing more of this as we move forward since both sites are collaborating with each other. So, even if you see credit on an Atarimania page given to the preservation initiative or one of its contributors, it doesn't necessarily mean that it is a "preserved" dump of that title. For example, I believe Caves of Rigel was not an original disk and so Atarimania's "Missing original disk image!" is still a valid statement. Zarxx or Atari Frog can correct me if I'm wrong here.
I didn't realise that the preservation initiative was utilizing cracked versions. It does make sense, though -- and not too unlike what Atarimania has been doing over the years -- to have a cracked version available (over none at all) until a clean copy appears.
I thought that might be the case with "Caves of Rigel", but as I've said, it's not entirely clear within the language of the comments section.
The only way to know for sure if a file is an original dump that the initiative created is to check the dump page for that title at a8preservation.com. For every dump on the site, there are CRC, MD5 and SHA1 hashes that can be used to confirm this. Furthermore, we now show the number of times a given dump has been verified against other independent dumps. So, if that number is > 0, we consider it "preserved". This fact is also represented by the inclusion of [!] in torrent file names. As an aside, we also publish a CrlMamePro DAT file with every torrent release so you can use a ROM manager program to manage things as well.
I usually use a file compare, but sure, a checksum will work too.
Thanks for clearing things up on the preservation initiative's side. It's all good information.
Do you have other examples? I believe the great majority of the pages should be accurate. I was absent for about four years so maybe some of them need an update. Some of the games / pages are revised on a regular basis to weed out he inconsistencies, missing information, horrible screenshots, bad dumps... so it's a constant work in progress
Ironically enough, the first example that came up was an ATR submitted by me.
I dumped this baby, so... I guess it was just an oversight.
Thanks to Mr. Fish from AtariAge for the scans and dump!
Missing original tape and disk images!
This may not be a preservation initiative pair of files (two sided disk) on AtariMania, but they come up equal with Farb's images using a file compare.
So, given the information from Farb above, these are clean dumps. Maybe it was unknown at the time, if AtariMania had obtained these years ago?
AtariMania: 221B Baker St.
Missing original disk image!
I have no file for comparison with this example, but it's unclear what kind of file is available, if it's not a clean copy. Is it a copy of a cracked version? At this point, that would be my assumption.
AtariMania: Pondering About Max's
Many thanks to Gobo for dumping this rare and highly unusual game!
Missing original disk image!
Other than the first two cases above, I was not able to come up with any others that I could 100% identify as improperly commented. But for many examples on AtariMania with disks available and "Missing original disk image!" comments, there was no alternate copy available in Farb's collection to use for comparison.
Now there may also be the case of a disk that comes from an original in .atx format but still hasn't been verified against another original. The problem is that, for years, when Atarimania was the only database / source trying to differentiate cracks from originals, a single .atx / .rom / .cas file was often deemed to be enough (or nobody really cared). With Farb's, Kr0tki's, ijor's, DjayBee's... efforts, things have changed for the better and maybe the pages on Atarimania will have to adapt and reflect this better (or in a less confusing manner).
That would make sense, if you're, now, waiting for verification against other copies.
I was under the impression (by my own assumption) that once a retail copy was created and deemed fully-working, then it was case closed at AtariMania -- unless more copies happened to appeared.
Thanks for the information. It's a huge undertaking, especially since AtariMania branched out to include other Atari platforms than the 8-bit computers (which it formerly catered to exclusively).
