Naaa... Most people would probably just look up and order a $7 to $12 official Dreamcast battery before realizing that Duracel and Energizer make them, and Wal-Mart stores sell them as cheap as 97 cents. You ever look up auctions on eBay for "SEGA SATURN MEMORY BATTERY" or some variation? I even thought about trying to sell 97 cent batteries for over $5 each on eBay at one point, but decided that I couldn't do anything that crooked without feeling guilty.
