"Save Your Saves" Talkback
Save Your Saves!
I thought this topic was interesting to research. Hopefully it'll be interesting to read.
According to the Retrode homepage, there are ways to alter the device so that it accepts NES and N64 carts, but the process involved was too technical for me to understand. They give you an extra circuit board and you're on your own.
My favorite one of these devices was one for the SNES that saved scores and games...3.5" floppies. I haven't seen one of those in ages but I heard that someone figured out how to edit the saves from the floppy and there was a lawsuit...
