Ok, so I'm selling my Nintendo DS Lite with a TTDS, EZ Flash 3 in 1, and a 2GB MicroSD. I put it on Craig's List and someone is interested in buying. They asked me this: "Has the DS BIOS been flashed?" Sorry if this is a noobish question, but I really I don't know what this means. If someone can help me out, I'd appreciate it.
