Disk2fdi

IMHO, this old hack isn't really interesting : you must use 2 PC floppydrives and paid 30 € to unlock the feature of writing FDI files... there's lot of other hard solutions more convenient !
 
Personally, i keep my Catweasel MK3 card, it's fast and amazing to use ;-P

Yeah, http://www.kryoflux.com/ or https://twitter.com/DiscFerret is better than disk2fdi.
 
Especially for me as my laptop would otherwise have no way of plugging in any floppy drives (or a catweasel for that matter).
