So I have a question: What kind of battery does the Dreamcast VMU have in it, and if I replace it, will I lose all my data?
How long do they last? I have a megamemory brand VMU that I got second hand from a pawn shop. It's lasted me about two years so far, but..
I'd like to get my grubby little paws on like new 3-5 Sega brand VMUs..
