this is weird(burning dc image from cd-rom)

[webber]

i am an electrical engineer and i can tell you that it is impossible to do a straight back up of an original dreamcast game from a CD-ROM, the technology from the GD-ROM is not identifiable and is non-readable on a normal CD-ROM,
the only methods are with the serial port connection, which i have made, and converts your dreamcast to a GD_ROM reader then you can manipulate the extracted files (this of course requires some knowledge of the file system on the GD-ROM) to properly set it up for a working backup burn
