Today I learned: the Amiga emulator FS-UAE by default uses copy-on-write for floppy images. And you can only disable that with a writable_floppy_images=1 config option mentioned nowhere in the launcher.

So if you're trying to prepare an ADF floppy image for an Amiga with a Gotek floppy emulator, and the disk keeps looking empty, it's because there's a copy-on-write overlay on the PC running the emulator and the ADF file never gets updated.

in other words, I totally thought I was going nuts but no FS-UAE was gaslighting me

@relsqui literally several attempts involved going up and down stairs because the amiga and the pc were in different rooms 😅 sneakernet madness. eventually I switched to a laptop

I'm making a note here: HUGE SUCCESS
