That's my ROM!
Unfortunately apparently the floppy disk bootstrap code is broken on metal (I don't have a floppy drive to test with yet). I don't know anything about the FD1797, and damn little about the Z80 - so all this together means I'm having some trouble figuring out where to even start.
But there's the source code, if anyone can fix it.
