Incidentally this may be one (of a few) reasons why LS-120 drives are better at reading dodgy disks. They may have a completely different controller than a normal PC (since they don't have to retain PC Floppy compatibility) so they might be able to apply more advanced algorithms to the data.

A member of the MAME team seems interested in them, so we may completely reverse-engineer the LS-120 on behalf of MESS before it's all said and done, and know for certain about the algorithms. Will probably be a while though. 😀
