The following disc is titled NPDP-GDEV GCT-0100. It is an application which emulates a Nintendo GameCube Disc with the files on a PC using an NPDP-GDEV. With ODEM, the emulation can be carried out directly with the files on the PC, without building a GameCube disc image, and this contributed to greater debugging efficiency. ODEM also supports emulation with an access speed close to that of the actual drive. (This function can be enabled or disabled. When it is disabled, debugging which does not need to take into account reading speed can be carried out faster).
