| Edit: Thanks for the clarifications :)

| 1.) Support for non-standard formats.
|
| 2.) Ability to capture raw flux images, bypassing the
| limitations of actual floppy controllers, and allowing for
| weird formats to be preserved and written (ex. of flux images
| bypassing rare hardware restrictions:
| https://www.youtube.com/watch?v=vCU4xbHFb58&t=1538s)
|
| 3.) Can allow for drives with weird quirks.

| Nah, that wasn't it. It was a real Mac floppy. No PC could read

| A Greaseweazle to the rescue! Created a floppy image. But how to

| the document, export it to RTF and Bob's your uncle!

| For the record: I think you're talking about
| https://infinitemac.org/ - right?
