Floppy Emulation from disk images
Last modified: 14 August 2024
The HxC Floppy emulator firmware for Gotek support floppy emulation from disk images. You have just to copy your floppy disk images files to the usb stick.
|
Note
|
If you are using a Gotek without any OLED/LCD/OSD screen in indexed mode you probably also need to rename the file images using the "DSKAXXXX" naming convention. See the usage page for more details. |
Supported disk image file formats
Here are the disk image formats directly supported by the HxC firmware :

Beside of that the HFE files can be generated from almost any types of files images with the HxC Floppy Emulator software:
This software is available on Windows, macOS and Linux.
You can use it to convert all these file disk images format to the HFE format.

Note
|
Beside to these tables, you can also define your own floppy disk format in the HxC Floppy Emulator software and in the HxC firmware, so all existing disk formats should be supported ! |
|
Note
|
HFE images vs raw data images (IMG,DSK,IMA…) |
HFE is a new MFM/FM or GCR encoded floppy file image format. The HFE format keeps intact all the informations present on the floppy disks tracks: sectors metadata and data, error detection codes (CRC) and so on. Unlike the older raw data images like IMG, this file format is designed to support most of the existing floppy formats and keep intact all the floppy format metadata. No more guessing or configuration needed to be able to read the images!
From a safety and data integrity point of view, the HFE keep intact and doesn’t bypass the original disk controller data integrity checking mechanisms to be able to check that the data loaded from the flash memory media (USB, SDCard…) is valid.
About the older raw data images IMG, please note that no emulator nor software is able to detect a corruption from a raw data image IMG file in a reliable way ! These images don’t have any data integrity protection mechanism, and there is no way to properly detect if a sector contains valid data or not. With these kinds of formats, the floppy emulator/software can only encode them on the fly and potentially send the corrupted sector(s) to the machine as "good data". The machine can’t detect the error(s) since error detection codes (CRC) are recalculated on the fly by the emulator and this generally leads to undefined behavior and may generate potential serious damage in sensitive applications.
For these reasons, we generally discourage the use of IMG formats without data integrity checking mechanism for industrials and medicals systems and we recommend to use the HFE format or something similar instead.
And even for music and video games applications, it is unfortunately easy to find corrupted images, stated as "good" today, due to, for example, a past flash issue, a copy/write issue to the sdcard/usb stick and so on…
