JFD recording files

I'm making these recording files available to allow original game floppies to be imaged on later machines that they won't necessarily run on, without ADFFS. You could for example use them to image original floppies on a StrongARM RiscPC or Iyonix.

To use them, follow the ADFFS !Help instructions (included below) on how to image a floppy, skipping steps 1..6 which detail how to create the recording file. Extract the correct dat file and modify in_file$ in !ADFFS.ConvRec.ConvRec appropriately. Ensuring you also enter all the other metadata detailed in step 7 to ensure ADFFS knows which game/floppy it is.

Where there have been different releases/versions of games, ensure you get the correct dat file, again the !Help file contains all the game names and ID's at the bottom. I'd suggest copying the details from !Help into ConvRec to ensure they're correct.

No support is given for these recordings and bare in mind, if the floppies you're trying to image weren't generated with a floppy imager or are a different version, they may not image correctly as the files may be in different locations on the disc. For the most part though, they should produce working images for use with ADFFS on ARMv4+.

Code: Select all

Imaging floppy discs

Requirements: At least 1500KB in the Next slot
              At least 64KB in the Free slot

1. Clean boot the machine (this is to ensure the floppy has not been
   seen by ADFS)
2. Load !ADFFS
3. *ADFRecord adfs::4.$.Fiiiiidd
     iiiii - is the ID from the table below
        dd - is the disc number (eg 01, 02, 03 etc)

   eg Flashback disc 1 would be F1015901

4. Insert the floppy and copy all files to a temporary folder on your
   harddisc.  You may delete them as soon as the copy has finished,
   this step ensures all used sectors are seen by ADFFS.
5. Run the game, once its fully loaded or prompts for another disc,
   press SHIFT-CTRL-F10.  If there's no protection or you're imaging
   disc 2 onwards, you can skip both this step and step 6.
6. Reboot machine (if you've had to run the game)
7. Open !ADFFS.ConvRec.ConvRec in an editor and change the following

    in_file$     = "adfs::4.$.<file name from step 3>"
    out_file$    = "adfs::4.$.<file name from step 3>/jfd"
    title$       = "<title> (<year>) (<publisher>)"
    discs_in_set = <number of discs in the game set>
    this_disc    = <this disc number>
    official_id  = <ID from ID table>

    If the floppy is an HD floppy, also set:
    floppy_is_hd = 1

    If you're unsure of <year> or <publisher> again, JASPP will
    correct those.  <title> is indicated in the ID table.

    You can ignore all other flags, JASPP will test and set those.

    eg.  Imaging Flashback disc 2 the settings would be:
    in_file$     = "adfs::4.$.F1015902"
    out_file$    = "adfs::4.$.F1015902/jfd"
    title$       = "Flashback (1994) (U.S. Gold)"
    discs_in_set = 6
    this_disc    = 2
    official_id  = 10159
    floppy_is_hd = 0

8. Make sure the floppy is in the drive
9. Run !ConvRec
   If the JFD file is 0 bytes, its likely you don't have enough
   free memory
