Support for P64 disk format?

[robertjmcintyre]

There are a handful of titles that can't be successfully represented in the .g64 format, primarily due to multi-density tracks. There's several discussions on lemon64, etc. on the topic.

We are able, however, to create working .p64 images of those titles, so would like to ask for you to consider adding support for that format in the 1541 Ultimate II (and Ultimate 64).

You can find a description of the file format here:

and VICE has full support for it. If you decide to take this on, various images for testing can be provided.
