A little better: Does the CoCo driver in the MAME emulator support hard drives?


But it doesn't emulate any known system.

If you execute the following command:

./mame64 coco3 -listmedia

You'll see two "harddisk" options.

You'll start MAME with a command like this to attach a hard disk image:

./mame64 coco3 -hard1 bigdisk.img

There is an driver in the NitrOS-9 repository called emudisk.dr (and
it's supporting descriptors: h0.dd, h1.dd and dd.dd) that will access
the image thru the emudisk interface.

The image format is a raw data, no structor, no header, no footer. The
emulator support reading and writing 256 byte sized chunks.

I don't know if there is a HDBDOS version that supports this interface.
