I highly recommend to add some documentation how to create a floppy disk with the game. Writing a 40 track floppy is not a daily task even for an experienced Commodore user like me and was quite a puzzle!

In order to help other buyers, here is how I did it: I started with a Commodore 64 with my 1541U2 connected and configured as device 9 and a real 1571 floppy drive connected as drive 8. I used the Maverick copying software. Mount Maverick on the 1541U2 on device 9, load Maverick and select the dual drive GCR nibbler. Then modify the parameters in Maverick to copy all 40 tracks. Now mount the Pet's Rescue D64 image on the 1541U2. Insert a blank floppy disk in the 1571 (can be unformatted). Start the copy operation and the floppy is being created.

Disconnect the Commodore 64 and connect the Plus/4, you can now run Pet's Rescue directly from the 1571.

  • Using a (real) 1541 or 1541-II instead of a 1571 should work.
  • The created disk should be compatible with a 1551, but a 1551 cannot be used to create the disk on a C64.
  • A Commodore 128 counts as a Commodore 64 here.
  • Forget about an SD2IEC: it is not compatible enough for nibble copying. You will really need a 1541Ultimate II.

Can I use ZoomFloppy in order to create the PETRescue disk?

It may work: The d64copy utility has and --end-track command line option, so with --end-track=40, it might do the right thing. Wether it really works... needs to be tested.

Thanks for your answer. I usually use ZooomFloppy with openCBM user interface. Can you explain step-by-step how to tell to the ZoomFloppy to write a 40 tracks disk?

I don't have a Zoomfloppy and thus no experience with the OpenCBM tools, unfortunately.
