DC DVD-burner

[silentpanda]

is it possible to read DC game disks on a DVD-r/rw drive. i know that GD-roms are about 1gb in size, so i figure if a DVD-rom can read a 4gb disk, then why can't it read a GD-rom? is the format different or something ? has anybody tried ? i figure if a standard red laser allows you to read 700 mb and a standard dvd blue laser lets you read up to 4gb and GD-rom is somewhere in the middle then what is there to stop you?

is it a copy protection thing i.e. some other color laser and such

the reason that i ask is that while i know that the DC- emu project is still in the works, if they ever were to work then i would have to locate warez - which is a pain in the butt. i would rather just buy the game ( since it is only $9 sometimes ) - than do the whole cable thing or beg people to let me download a copy of sakura tisen 4
