.d64 images

Note: Install Vice first (see above) to provide the c1541 binary

List the contents of a .d64 image

c1541 -attach IMAGE.d64 -list

Extract all files from a .d64 image

c1541 -attach IMAGE.d64 -extract
for file in *; do mv "$file" "$file.prg"; done # (Optional)

Extract one file from a .d64 image

c1541 -attach IMAGE.d64 -read SOURCEFILE DESTFILE.prg

Extracting files from a corrupt image

If you get an error reading or extracting files from a d64 image using c1541:

If the image was created with d64copy (ZoomFloppy/OpenCBM) try recreating it using -b/--bam-only
If that’s not possible or it doesn’t work, check the file size
If the image file is bigger than 174848 bytes, open the file in a hex editor
Verify that there’s no real data past 2AAFF. If it’s just 00s or 01s then it’s safe to trim

Trim the image

dd if=image.d64 of=image-trimmed.d64 bs=1 count=174848

Try using c1541 again on the new trimmed image
