I've tried a bunch and I keep seeing that. I'm using version 2.1.6.0 of HxCFloppyEmulator and the version of the Amiga autoboot file selector is 1.46a. My firmware is 1.8.2.40.
A search on the forums mentioned it could be the power supply so I switched from using the internal Amiga power for the floppy to a stand-alone one, same issue.
What can I do to debug/fix this?
