Using Floppy Images

Here’s FS-UAE Launcher with a floppy chosen for DF0, which is also added to the floppy swapping list.

You cannot generally use Amiga floppies in a PC floppy drive, and FS-UAE does not support using real floppy drives. Instead, you need a floppy image – a file with a copy of the data contained on a floppy.

FS-UAE supports floppy images in multiple file formats: ADF, IPF, DMS are the most common. ADZ (compressed ADF) and ADFs in zip files are a also supported.

When you use FS-UAE Launcher, you have a convenient GUI for insert files into floppy drives. Also, there is a Select Multiple Files function where you can select multiple files for a game, and the files will be inserted into all available drives and also added to the floppy swapping list.

Floppy Swapping

To be able to change floppy disks during play, the floppy image files must be added to the list of swappable floppies. When you use FS-UAE Launcher, this is easy. In the “Floppies” tab, there is a GUI to manage the list of floppies. If you don’t add anything to the floppy list, the floppies assigned to floppy drives will automatically be added to the swap list.

When running FS-UAE, you change disks in the floppy drives from the on-screen menu by pressing F12.

Note: Even though FS-UAE supports up to four floppy drives, a game may not support using all drives. Some games supports only reading from the first floppy drive. In this case, you must use the floppy swapping feature to swap the disks in the first floppy drive.

Manual Configuration

If you use FS-UAE manually, you specify floppy images for drives in configuration files (see the documentation for these options for more information.):

floppy_drive_0 = Pinball Dreams (1992)(21st Century)(Disk 1 of 2)[cr FLT].adf
floppy_drive_1 = Pinball Dreams (1992)(21st Century)(Disk 2 of 2)[cr FLT].adf

When a game has multiple floppy disks, there are two ways to set this up in FS-UAE. One way is to use multiple floppy drives, and put one disk in each drive like you would on a real Amiga with multiple drives:

floppy_drive_0 = Pinball Dreams (1992)(21st Century)(Disk 1 of 2)[cr FLT].adf
floppy_drive_1 = Pinball Dreams (1992)(21st Century)(Disk 2 of 2)[cr FLT].adf

You can emulate up to four floppy drives this way (floppy_drive_0…floppy_drive_3).

When a game has more than 4 floppies, or the game supports just one floppy drive and requires floppy-swapping, you can do this instead:

floppy_drive_0 = Pinball Dreams (1992)(21st Century)(Disk 1 of 2)[cr FLT].adf

floppy_image_0 = Pinball Dreams (1992)(21st Century)(Disk 1 of 2)[cr FLT].adf
floppy_image_1 = Pinball Dreams (1992)(21st Century)(Disk 2 of 2)[cr FLT].adf

You are then able to swap floppies using the FS-UAE menu. In the above example, Disk 1 is inserted in drive 0, and both Disk 1 and Disk 2 is added to the floppy image list. You can add up to 20 floppies to the floppy image list using the floppy_image_* options.

Floppy Overlays and Writable Floppy Images

By default, changes to floppy drives are not written back to the original files. The changes are instead saved in overlay floppy files. FS-UAE stores these files by default in Documents/FS-UAE/Floppy Overlays.

If you want to, you can use the option writable_floppy_images to enable writing data to the original files instead.

  1. The final “f” character is missing in this line:
    [code]
    floppy_image_0 = Pinball Dreams (1992)(21st Century)(Disk 1 of 2)[cr FLT].ad
    [/code]

  2. Hi, I’m really sorry as this has probably has been asked before but what is the simplest way to play a game with multiple floppies? Every game i have with 2 or more floppies i am unable to use as when the game prompts me to insert the next disc (which i have in the 2nd drive) nothing happens. I’m no computer whizz so i don’t understand all the talk of directories etc. Is there not a way to select the disc in the other drive whilst playing the game?
    Thanks

    • You need to select all the floppies in FS-UAE Launcher before starting FS-UAE. Then you can (if necessary) change disks while FS-UAE is running by pressing F12. The simplest way to select the floppies is to use the button “Select Multiple Files…” on the main tab in FS-UAE Launcher.

  3. Hi, I have a problem with the game Dune II: Battle of Arrakis. when I am asked to insert Saved Game Disk, nothing happens. I use the Disk 6 (I assume it is the saved game disk) but it doesn’t seem to be “read”. Any suggestion ?
    I was wondering if this comes from the write enable/disable option of a disk.

    Thanks.

    • Dune II has only 5 disks (there is no disk 6). When you start the game, you should be asked to choose between:
      1 - Create save game disk
      2 - Play DuneII

      You should choose (1) the first time. If you start the game via FS-UAE Launcher, the launcher already provides a save disk for you, automatically added to the floppy swap list. So when asked to insert the save disk into DF0, use the F12 menu to change from Disk 1 to Save Disk in the first floppy drive and press RETURN. The (save) disk should then be formatted for use with Dune II. After this is done, just follow the instructions given by the game.

      • It worked, thank you very much ! Just one additional thing, the (ambient) music was not working (only the sounds), so I set the memory chip to 1M and it worked.

        Thanks.

        • Thanks for the info I’ve modified the online game database entry to use more memory 🙂

  4. sentite come devo fare?fsuae non mi parte manchester united europe dice di togliere la protezione come si fa?

    • Hi, can you provide some more details about the problem? When does it happen, and exactly what happens? Also, if you could write in English that would be great (I don’t speak Italian).

      • Simply put: on disc loading, slightly after the first (usual) splash screen, a graphic animation resembling a floppy disk turned upside down indicates that the disk must be write protected for the game to start.
        Googling the issue shows that the adf file itself must be write protected on the OS to make the emulator aware of its write protection. But, in my case (tried on OSX with the file on the filesystem and on a Windows share) to no avail

        Thanks!

          • Thanks again for your time and effort!
            Let us know if there’s any update on this matter!

          • Another thing that could be related. I messed up and managed to start installing wb3.1 onto the wb3.1 floppy rather than the HD image I was intending to install on. Now S:Startup-sequence is gone. Interestingly enough I can’t find anything under “Floppy Overlays” and the ADF itself is write protected by the OS (and indeed doesn’t show any changes). I had to RENAME the adf to get it to boot again. Any hints as to what I’m doing wrong?

          • The floppy overlays directory isn’t used any more. Now, the overlay files are stored in the Save states directory (more specifically, in a sub-directory specific for each configuration). You should find the floppy overlay file there 🙂

  5. I’m trying to run Space Crusade but it’s requesting the following “insert data disk in internal drive”. I’m assuming that I need to make a save disk of some sorts but I can’t figure it out / het it to work. Any ideas?

    • In this case, the game means disk 2 when it says data disk (you can assume the disk label on the original disk says “Data Disk”). And the internal drive is the first floppy drive. So you need to use the F12 menu and change the disk in the first drive (from disk 1 to disk 2). Before starting the game, you should ensure both game disks are added to the floppy swap list as explained on this page.

  6. Hi,

    How can i load monkey island 2 from commandline, its 12 disks and im struggling with what the proper combination
    of –floppy-disk-x and –floppy-image-x should be,

    thanks,
    /yates.

    • You should choose all disk images with –floppy-image-0 through –floppy-image-13. And then you can use –floppy-drive-0 to choose the boot disk for the first drive. Using –floppy-drive-1 through –floppy-drive-3 is optional. You can for example add disks 2, 3 and 4 here to enable more floppy drives…

      See the Pinball Dreams example on this page (where you see that all disks are listed using the “image” options” and only one is inserted using “drive” options.

      • ah ok got it, cheers mate.

        /yates.

        btw it would be nice if the floppy image names would scroll when f12 is pressed, i have to shorted all
        my filenames to be able to read the disk numbers.

  7. Hello… I seem to be having problems attaching some disk images that I’ve gotten from various sites. For instance, Poet’s download for the Northstar-Fairlight Megademo II (a DMS image) refuses to attach – I select the file but it doesn’t go into the floppy drive.

    Anybody else having this problem? (on Launcher 2.3.99 beta1, Mac OS-X)

    • Hi, please start the launcher, select the floppy image (so the problem occurs), quit the launcher (so the log file will be completely flushed), and send Documents/FS-UAE/Cache/Logs/fs-uae-launcher.log.txt to frode@fs-uae.net. Thanks 🙂

  8. I can’t access the on-screen menu on my iMac. If I hit F12 it switches the screen to the widget window.
