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. Hi evrybody! I have a question. I have install FS-UAE on retropie. The problem is , i cant play roms with two or more adf files. Via retropie game list menu i can change only one adf file. Is it possible to create a +start Fs-uae on amiga game list? Is there another way to fix this issue? Many thanks.Aggelos.Greece.

    • Hi, sorry, this site has nothing to do with RetroPie, you must try to ask on their forum instead!
