Re: Dumping and Emulation Issue

Very interesting! I know that there is a broken copy out there that works on DosBox, so I wasn't sure about mine. According to this site (https://www.vogons.org/viewtopic.php?t=50664&start=40) the disk won't work at all on any CGA/EGA, etc. past the title (which is what happens on my dump), so ...

Re: C64 format info

This is far from complete and also contains some errors. A lot of details also missing. If you have better information, please just let me know. I don't have the time to check every title or submission extensively. Why do you think I am asking for it here, where I know someone have technical detail...

Re: Help Analyzing Kryoflux Stream

A lot of times the disk is either detected as the wrong size or has protection on it (or just bad areas). Both of these conditions make basically a blank IMG file, or one that WinImage or other programs can't detect.

Re: How to write ADF to disk

They are much closer together in coercivity than 5.25 media, but it is not the same and can be unreliable. The physical disk is actually half the thickness as well. I've heard people claim that HD disks are "higher quality" and you should write DD data on them because it will actually be m...

Re: Apple II disk Grrr.....

Specialized hardware designed for that specific platform will always be ahead in features. KF can image the disk, but conversion to other formats has to be written by someone.

Re: Commodore 1571 track offset in double-sided mode?

No, it is not offset. It is directly over the other head... 99.9% positive, although I haven't looked at it in years. :)

Using a 40-track drive

I recently discovered one of my rescue 5.25" drives is an old 40-track (41, actually). Thinking I could adjust the DTC parameters to write out disks for old 35/40 track media, I tried to do it, but could not end up with readable disks. Is it possible to write out an 84-track G64 file on a 40-tr...

Re: G64 with mastering information?

These images do have track 18 where normally track 17 is located, so they are misaligned or offset by one track. I have modified nibconv so that it looks at what track it found when it tries to read track 18, so if it sees another track instead in the headers, it figures out how far off it is and ex...

Re: G64 with mastering information?

Are we talking about disk images where there is some alignment problem and track 18 is not on track 18, but stepped off a half or whole track in one direction? That's a data problem, not a tool problem. I mean unless this is mastered this way on purpose with a drive that is out of alignment?
