Unlike most other consoles that use CD-ROMs, this system's CD-ROMs are inside a plastic case to protect them from damage from touching, similar to 3.5" floppy disks or UMDs. The discs use the ISO 9660 file system, without any copy protection other than a simple sensor in the case jacket, making it possible to make a disc image from the disc. However, there are no known cases of piracy involving the V.Flash. Because of this, the V.Flash can also play audio CDs and user-recorded CD-Rs using the disc adapter that comes with the console.
