I've been trying to get this to work, but given my tries I'm inclined to think that the X68K driver doesn't support disk writing/formatting yet? Hopefully one of the devs can comment.
Here's what I did:
Following the translation, I booted from the second dracula disk while having an empty disk (created by MESS) with read-write access in drive B:. Regardless of holding OPT1 it brings you to a menu, where I assume the yellow marked option as shown below is the one to get the user disk created in drive B (it accesses drive B: on selection, so I guess that's right).
Unfortunately, this brings you to the <A>, <R>, <I> screen as posted below, which I assume to be the classic Abort, Retry screen.
"FORMAT B:" in the shell. It comes up with an error after accessing the disk. Then I made a copy of the HumanOS disk (in Windows), inserted this disk in drive B: with read-write access and tried erasing files from it by doing:
"DEL *.*", or "DEL config.sys", but it returns the Abort, Retry error after accessing the disk.
My bottom line conclusion as such is dat disk writing isn't yet supported in the X68K driver?
