I have two questions regarding the KryoFux and Apple II nibble disk images:
- Is it possible to make a nibble disk image file out of an Apple II floppy disk?
- Is it possible to write back a nibble disk image file to an Apple II floppy disk?
Nibble image holds nibbles as if they were read by the Logic State Sequencer, therefore some protections may be lost (and I assure you they are). Each phase contains $1A00 (6656) bytes. A standard $22 diskette (step 1 track) is 232,960 bytes long.
I'm having trouble finding the HxC disk utility. I tried the downloadable software from the HxC main site, but it doesn't support Apple II that I can find anywhere. I'm mainly looking to do things the other way around, though. That is, try and convert my KF stream files to one of the Apple II formats that supports copy protection. I know the .NIB format doesn't support them all, but maybe it supports the few that I have, enough to work in emulation. There may be a couple of others (look HERE for what I discovered previously,) but that one seems to be the main one.SomeGuy wrote:At one time nibble files were popular on Apple II emulators, as it enabled them to run many copy protected titles that used less complicated protections (such as alternate sector header bytes). It may have also simplified the program code, but most emulators eventually supported 140K disk sector images.
It looks like the HxC disk utility can read in Apple II nibble files as long as they have the .nib extension, and seems to save them as a KF stream file OK.
