Kryoflux - Has anyone used one?

I purchased a Kryoflux board with the hopes of having a simple all-in-one solution to dump write-protected floppies. Has anyone used this device for MSX yet? I have set it up and got the CLI to run but I haven't executed any copies yet.

After ripping, I think the second hurdle is going to be converting to a DMK file, and I'm not sure if that's going to be straightforward.

It might take a little work to figure out, but I think it will be useful for people who don't have a non-Panasonic MSX, and potentially for shipping to people if necessary.

I'm very interested in the results!

Didn't Louthrax bought one a while ago?

I am also interested to read how it goes for you. I have one too but haven't tried it on MSX floppies yet.

I heard the way to go if the write-protection scheme is unknown is a raw rip and then convert to DMK via HxC tool.

Does anyone happen to know for certain if Ultima IV has copy protection? I just want to confirm the operation with a less rare disk first due to my paranoia. If I can get it to work for IV then I can probably get it to work for III as well.

BTW, I have confirmed that the disk boots. That's good news: Ultima III FD version boot sequence on Youtube

Hoping to have a little extra time tonight to try a disk rip.

Did it work for you and how did you convert the files with HxC ? Do you just drag and drop the first stream file to HxC and then export as .dmk? (I am unable to boot from disks converted this way)

How did you try to boot from the DMK file? I assume in openMSX, as it's the only MSX thing supporting DMK?

Yes, I tried it in openMSX mounted as A:, it just tries to read from the drive in an endless loop. If I convert it to .img and then rename it to .dsk it boots but complains that the copy-protection is incorrect.

Interesting, perhaps you can send it to us so we can investigate what's going on.

Great! I sent you an email with a link to the dump to investigate.
