This uses a small ASM stub (the CA65 source is on the disk image, lol) to
do the dirty work.

It can create partial and total disk images, although I haven't tested it
with total images, of 5.25" disks in slot 6 (either drive). I wrote it
mainly because I'm working on a crack project that would benefit from it.

What does that mean, exactly? Is that like formatting - it writes out a
filesystem structure? Or does it copy disks? Or...?

datawiz

It dumps a track, or range of tracks, that you specify and BSAVEs them
as a single file on a ProDOS disk. The result is the same as a disk
image of you specify all tracks to copy.

I see how this fits into your Donkey Kong project, Steve.
Best of luck and thanks for the code!

Ah, got it. Of course you'd need a destination storage device larger
than the source to actually create a full image. :-)

It creates a .dsk file.

Currently for some mysterious reason it leaves off the last track when I
tell it 0,34... o.o;

Which is why I didn't initially test it on full disks >:P. Had to crack
out KEGS.

Your assemble code has one bug:

*?

Before $9019, perform a LDA $9004 again and that will work like a
charm.

Big surprise, lol... I always make silly mistakes. >_< Thanks... fixed.

Also fixed a typo in the BASIC side.

LOL, it's a good thing I keep the LST file handy. xD

Good job, that works better and the extra PRINT is away too ;-)
