Re: Write Only One Track

Aw, how cute. Someone who still thinks modern electronics should do what the user wants, not what the corporate overlord wants.

Re: IBM PC disk-based copy protection schemes and games

Ok, here is a more complete list of known copy protected productivity application titles based on what is archived on Winworld. Something to keep in mind, however, is that much copy protected application software simply has not been archived. It is also not always clear if some early titles were cop...

Re: Need advice on how to recover 5.25" floppy

"C:\path\01.0.raw" -e81 -d0 -dd1 -w"

It could be that you confused things by not exporting with a full filename. Typically when I export from HxC to KF raw, I export with the file name "track" so I get track00.0.raw, track00.1.raw, track01.0.raw, etc, the same as the KF GUI.

Re: IBM PC disk-based copy protection schemes and games

is Transcopy really a worthy opponent to KF and SCP? I know it's obsolete and poorly documented, but at the end of the day, I noticed people with a vast expertise in this area eventually end up being in favor of Copy II PC Deluxe / Transcopy. One of the catchy pros is compact size, but I know nothi...

Re: IBM PC disk-based copy protection schemes and games

Could you name any specific ones? One that comes to mind is VTERM II because it was so simplistic. All they did was write a compleatly normal format to the 41st track. The program checks for it and refuses to start if it is not present. Some other protected titles are in the "IBM Personally Develop...

Re: IBM PC disk-based copy protection schemes and games

What, no productivity applications? Many, many, early titles did rely on simplistic custom copy protection methods. it would be great to know which tools and software/hardware combinations are most suitable for every specific type of CP method e. g. Teledisk, Transcopy, Kryoflux, Supercard Pro, etc ...

Re: Alley Cat Booter problems

Personally, I find it easier just to write low density images using a genuine 360k drive. It is possible to convert a copy of an existing KF stream dump that was made using a 1.2mb drive by deleting the odd number tracks and renaming the remaining ones so they are consecutive. Even though the tracks...

Re: Alley Cat Booter problems

Did you perhaps write it using a 1.2mb drive and try reading it in a 360k drive? That won't work reliably. You either need to write the disk in a 360k drive, or degauss the floppy first.

Re: Need advice on how to recover 5.25" floppy

That is a 1.2mb (96tpi/80track high density) floppy disk. You must read it using a 1.2mb 5.25" floppy drive. It will not read in a 360k (48tpi/40track low density) drive.

Re: Need advice on how to recover 5.25" floppy

Most "360k" floppy drives have issues reading GCR encoding. Your best bet at reading them is probably a "1.2mb" Teac drive. Of course, it is difficult to reliably write 48tpi (360k) images in a 96tpi (1.2mb) drive and KF does not support writing non-index aligned streams. But for reading and archivi...
