What does DVD-9 mean?
A. A dual layer DVD. Dual Layer discs advertise that they store around 8.5GB’s. This is somewhat misleading, as they actually store around 7.95GB’s of data. Swap Magic isn’t compatible with DVD-9 games at present. The only way to play a DVD-9 without shrinking it to DVD-5 (single layer DVD) is with a modchip that supports DVD-9, or HD advance 3.0.
