: Now, here's a question I've seen asked here several times, but I've yet to see an answer.
: Is there any way to make those *.dsk files, which are found inside the 99er.exe archive, readable by either v9t9 or Ami99?
They aren't useful for Ami99 due to the limited disk support. Ami99 can only read PROGRAM image files stored as single files on the PC hard drive.
V9T9 doesn't seem to like them, either, so I spent a few hours tonight looking at both formats. I have a written a program that rips through either disk on a disk format, displays the filenames and sector locations, and attempts to dump the files as individual PC files with V9T9 headers.
However, it doesn't (quite) work. PC99 disks seem odd to me, and if someone got me documentation on how the file is structured I would try again. I had thought they were just raw disk dumps, but each sector seems to be 334 bytes, not 256.
I'm likewise doing something wrong with V9T9 disk formats, probably in the header, as everything saves somewhat corrupted. (Oddly, I have a disk manager that works completely, but everything else loads corrupt or fails to load at all.)
Anyone have information on the structure of V9T9 files, and V9T9 and PC99 disk-on-a-disk formats? My program is prolly just missing a few minor things.
