for every console there is a specific list of mods that have to be done & a specific technique for making backups. Just cloning the original game with a program like DVDfab will NOT work.

I own a professionally modded Xbox 360 which will play backups but I had to buy a specific DVD drive with KREON firmware to read the security sectors from original DVDs & use that with the xbox backup creator software that was bundled with the drive to create a .ISO image
Once I have a rip, then I can burn it to Verbatim DL using IMGburn & keep the originals in pristine condition. Verbatim are very compatible with Xbox360 drives & I've found the HP DL are also very good, but seem to be unavailable at present.

I don't own wii but if I did, then I'd google how to make backups & get the specific tools for the job.

Note also that for on-line gamers ( which I'm not) it's an ongoing "cops n robbers" battle between microsoft & the backup software creators,

because if xbox live detects a cloned game in use, then it will permanently ban the game console ( not just the game! ) from ever playing on xbox live.
