In the past I have had different Super Wild Card copiers, one pre-DX model and a DX. I remember both had an option to transfer data from disk (floppy) to cassette.
Has anyone here ever used that option, and if so, what kind of cartridge did it require? Was it for use with official Nintendo development carts or did were these special carts for use with the Super Wild Card hardware? Or is this related to EPROM (don't now what it is really, just a term I find when trying to find more information about this online).
Edit: I forgot to mention this. I once owned an empty Super Famicom cart, that was used in Japan for 'downloading' games from an in-store machine. Has anyone ever tried this type of cart with the transfer to cassette option of the Super Wild Card?
