 We are also playing with a 3rd option which would allow any .msa disk image to be mounted and booted directly from an Atari HD - even titles doing direct disk access work using this method.  As we have stated many times previously, this is still a long way from being released, but it has been lab tested ;-)  Some working titles for this project are:  "ImpossiLoad", "NotImgRunner" and "ItJustWorks"


Wow, this intrigues me. I can understand you can intercept OS IO calls and redirect them to a virtual mounted floppy, but how do you prevent that programs (usually games and demos) executed from the mounted floppy, overwrite the memory area where the virtual floppy driver is living. And more difficult how do you intercept direct calls to the floppy controller registers of programs (usually demo disks) that skip the OS for doing IO.
But it would be the ultimate Atari ST utility now my floppies are rotting away. Keeping them as disk images on HD would be great. I hope it gets released sometime.

Regards,

Robert
