| shams said: @Darklight - you are right. The spec does allow for dual layer, 8.5GB discs. It however also does say that its the same format as the GC disc - "The disc is a proprietary version of the eight centimeter DVD (MiniDVD) format". This is not the same format as DVD-9, although the Wii may be able to read normal DVDs as well. |
They're both basically DVDs. They violate the DVD spec in places so that your off the shelf DVD drive refuses to read them (a possibility is introducing read and checksum errors in places), and they add some protection so that your off the shelf console refuses to read copies, other region disks, etc (the Burst Cutting Area is one example). But, as we know from piracy, it's as easy as flashing the drive's firmwares to make them work, which means, physically, they're DVDs.
