This looks like it's the wrong type of disk, either HD or DD. (DD disks have a stiffening ring around the centre of the cookie.) Either will work, but you...

I've checked and the default is `high_density=true`, so writing the C64 disk _shouldn't_ have worked. Could you try both the Apple and C64 disks with `high_density=false` and let me know...

If you zip it up first, you should be able to attach it.

Excellent --- let me know how you get on.

The basic problem is that your distribution is really old --- you need a more modern Python (as you've found) and protobuf tools. I should add some better version checks,...
