I was reading the beginning of this thread and the "fake Floppy" was something that looked like someone developed to replace the expensive reaI floppy drive. I tried to find the MiniModem but I could figure out how it worked with windows. Also once I have it on the PC I assume with the Save Extractor it cant get back. @slinga Is there a way to get make the program so I could use the link cable and run the save copier on both Saturns to move saves between cards?
Here's what I would do:
1) Backup all saves from Saturn->PC with Save Game Extractor. Verify the MD5 hashes are correct.
2) Burn all saves to disk and copy from PC->Saturn with Save Game Copier. SGC can copy saves from CD to the backup cart.
Another user got minimodem to work on Windows. I would recommend just setting up a Linux VM.
