So, the Atari 8-bit Software Preservation project has done some amazing work over the last few years using Kryoflux and SCP devices to make magnetic-level disk images of copy-protected floppy disks, creating disk image files in ATX format and distributing them via a periodic torrent seed. The current seed is over 700 megabytes and something like 1,500 individual titles.
Besides use in current versions of Altirra, there are a few options to use these files on real hardware - if one has something like an SCP device and a proper 5-1/4" disk drive, the ATX files can be written back to magnetic media and run like an original. I understand as well that use of AtariMax APE software with the VAPI.DLL file plugin will allow use of most/all of these ATX files on real disks, but of course APE requires use of a Windows machine or something like WINE or CrossOver. Such a solution is probably beyond using APE on low-budget hardware like a Raspberry Pi. Apparently there is also some new-ish hardware in work coming out of Europe called the SDrive-MAX that has firmware that allows use of these file from an SD card device plugged into the SIO port.
However, most of us using RespeQt obviously have and prefer using something on a separate box for our disk image loading/saving and general file manipulation purposes. To that end, one of the main participants in the 8-bit Preservation movement, ijor, has offered to assist people working on RespeQt to understand the file format and help add ATX file support to RespeQt. If I had basically ANY real understanding of C and Qt, I'd be all over this as my summer project. Alas, I have never used C of any kind, so trying to add support for an entirely new file format is well beyond me.
So I'm throwing out to wider Atari world. If anyone can help, please contact ijor! Please and thank you.
