Gameshark CDX - Can it be used w/ back-ups?

[Blade107]

HI,

I'm getting a back up of the Gameshark CD 3.3 for the Dreamcast and have a question(s) about using it:

Can one use it with Back-ups and can they be non-selfboot ones?

How do we go about saving the codes without the hardware part that comes with retail package?

In case that can be done with non self-boot games, considering one has to boot with the Utopia cd first, what are the steps to activate the codes to play the game?

Thanks for your input

Thanks alot, Great Forum here!
