I know I just keep going on about copiers, so sorry about that, but I was wondering if it is possible to install a 2.88 MB floppy drive into any of them, especially the SF7. Would a custom BIOS have to be made to add support like how it was done for the Z64 to support HDDs and CF cards?
SF7 supports up to 1.6MB or so. Do yourself a favour and avoid problems with an unreliable storage mechanism; get a USB Floppy emulator and install that!
Parallel interface wins, if it wasn't for the annoying fact that newish computer motherboard do not have parallel ports, and the USB > Parallel cables only work for printing.
If you're going to use the SF7, I recommend buying an old laptop with a Parallel Port. Put Windows 98SE on it. Get a frontend for uploading ROMs. Don't mess with disks, the CDROM, or any other garbage. Just have a laptop, you can easily send games with it. Even still I'd recommend you skip all that and buy the PowerPAK.
I actually have an old laptop that runs 98 (not SE though). I checked the port and I don't think that is has the correct drivers to connect, I might be wrong though. Can't Ucon install them for me?
Win98 doesn't need drivers to use the parallel port. WinNT, 2k, XP and up do. Really you should probably be able to just throw UCON64 onto a Win98 computer, hookup the parallel straight through cable and go. At most you might need to configure the parallel port mode in the BIOS setup screen, maybe.
