Slight correction: It's actually two tables to diffenrentiate between PAL and NTSC.

 

You are right, of course. And for those that wonder, the time is (almost) the same in both systems. Two tables are needed because they are in frames.

 

Btw, thank you for your reverse engineering work. It helped a lot investigating the issue.

A short message from "dump QA" (I attached what I have to fix these.). ;)
 

  • Atarischreiber (1983)(Atari)(DE)(NTSC)
    FIle name is nonsense there is no relation to NTSC
  • Atari Vereinsverwaltung (19xx)(Atari)(DE)(NTSC)(Disk 1 of 2 Side A)[BASIC]
    You put the bad dumps into the torrent and there is also no relation to NTSC
  • Print Shop Companion, The (198x)(Broderbund Software)(US)(Side A)
    Year: 1985, needs 64K, is version 1.1
  • Drelbs (1983)(Synapse Software)(US)[OS-B]
    Might be 810-only (you have to select 1050 in Altirra to make it run). Perhaps somebody can verify this on hardware
  • Square Pairs (1983)(Scholastic)(US)[OS-B]
    Needs BASIC
  • Wargame Construction Set (1986)(SSI)(US)(Disk 1 of 2 Side A)(Editor)
    is version 1.0
  • Space Eggs (1981)(Sirius Software)(US)[a]
    The only difference to the non-[a] version is the filler byte for unused sectors ($1A instead of $00)
  • Lasermania + Robbo Konstruktor (1990)(L.K. Avalon)(PL)(Side A)(Lasermania)
    Lasermania + Robbo Konstruktor (1990)(L.K. Avalon)(PL)(Side B)(Robbo Konstruktor)
    both are PAL-only and need 64K
  • All these L.K. Avalon titles need 64K:
    Wladcy Ciemnosci (1993-05)(L.K. Avalon)(PL)(Side A)[!]
    Klatwa (1992-06)(L.K. Avalon)(PL)(Side A)
    Kampania wrzesniowa (1993-04)(L.K. Avalon)(PL)
    Smus (1993-09)(L.K. Avalon)(PL)        ?
    A.D. 2044 (1991-12)(L.K. Avalon)(PL)(Side A)    (only true for .cas - .atr works with 48K)
    Zybex (1992)(L.K. Avalon)(PL)
    Constellation (1992)(L.K. Avalon)(PL)
  • Hellcat Ace (1982)(MicroProse Software)(US)[BASIC]
    Hellcat Ace (1982)(MicroProse Software)(US)[BASIC][a][p]
    NTSC-only - In PAL you can not type a number to select mission
  • Conversational German (1981)(Atari)(US)(Tape 4 of 5 Side B)(Unit 8 - I Like...)[a fixed][CLOAD+RUN][BASIC].ogg
    Conversational German (1981)(Atari)(US)(Tape 5 of 5 Side B)(Unit 10 - Actions)[a fixed][CLOAD+RUN][BASIC].ogg
    Both files are exactly identical which seems unlikely
  • U.S.A.A.F. v1.1 (1985)(SSI)(US)
    game disk is missing (Side B)
  • Mech Brigade v1.0 (1985)(SSI)(US)(Side A)(Scenario)
    Bad dump (missing sector in file FULDA)
  • Super Hangman (198x)(Main Street Publishing)(US)[b][BASIC]
    Superman - The Game (1986)(Main Street Publishing)(US)
    Probably bad dumps because these titles make no check for protection and have several bad sectors in unused areas of the disk

I shut down my torrent to stop spreading the errors and bad dumps.... I have also deleted it and will wait for the corrected torrent to appear...

I noticed some of the same things but didn't have time to make a complete list...

If you snag the torrent please take the time to peruse it and make sure it's all good.. on both pal and ntsc...

 

Thank you DjayBee for posting up a more complete list of what works or doesn't or needs correction...  +1

I took a look at the ANALOG Computing disks marked bad ([b]) in the torrent.  Issue 42 side B is marked bad, but all the files look intact and seem to parse as valid Mac/65 files, so perhaps the bad sectors are only in the unused portion of the disk (only about 1/3 of the disk is used).

 

Issue 76 on the other hand has a number of corrupted sectors in the files SKEET.M65, MLEDITOR.BAS and EDITORII.LST.  The last two files are on many of the disks, so restoring them is straightforward.  The SKEET.M65 file is in Thumpnugget's disk collection, which I used to restore the handful of corrupted sectors and fix the disk.

Thanks for your feedback on the current torrent, DjayBee. It's super helpful as usual. I've updated the database with your corrections and they will be in the next torrent.

 

And thanks, Atari_Ace, for creating a working disk image from ANALOG 76. I've updated that as well.

 

Oh, and according to my notes, Ijor mentioned a difference between the [a] and non-[a] versions of Space Eggs is the sector interleave. I don't know if that has any impact on filler bytes or not.

I wouldn't guess so but then it makes sense from a preservation perspective.

 

But maybe he can jump in and knows something about these $1A-sectors.

This value puzzles me for a long time because there are many images which have all "empty" sectors filled with $1A instead of a plain $00.

 

My guess is that it either depends on the disk duplication machine or the dumping equipment. Which would also make sense in relation to the different sector interleaves of Space Eggs.

I doubt that I will be able to supply anything new because I do not have a large collection from BITD and therefore am only acting on stuff which is public available.

 

Btw.: Check the Wiki's HTTPS-configuration / certificates. Current browsers deny to open the site.
