If you haven't read the comment on Transfer +3, I'll tell you that Discopack +3 is nothing more than an updated (improved, according to its author) version of the program published by Topo Soft in early 1988. In fact, the menu itself tells us so, although without mentioning the name of the original.

I said, in the Discology +3 page, that I didn't know if I had used that one or this one to convert some games to disc. Looking back now, so many years later, I realize I barely used it, so I've resolved the question.

In any case, I can repeat what I said in the other comment: I enjoyed the experience of ordering, waiting for, and unpacking it, which used to be a big part of the experience back in the day.
