The Nintendo Wii uses regular DVD media for its games. A few questions about the Wii's media. Is the Wii compatible with dual-layer DVD game discs, which enable ROMs to be approx 7.5GB? What does the Wii use as memory cards (if it uses memory cards, I'm guessing it uses SD cards but i'm not sure. Then again the discs may be DVD-RAM since I don't know) Since the Wii uses regular DVD media, what are the read speeds (and write speeds if applicable) of the Wii? x2 like regular DVD players or faster x8 or x16 drives? Also what are the read/write speeds of the SD card slot of the Wii? Thanx for any/all responses.
