It is imposible to play in my DC copied games.....

[Frustrated]

I just buy my DC a while ago, cause a friend got really nice games (you know, copied ones)
He told me he was going to burn these games for free.
Well, I ran into a shop and buy a new DC, that includes 2 Sonic Games (Sonic Adventure; Sonic Shuffle) and a VMU...
He gave out the games, but when I was about to play it, the games just didn't worked at all.
He gave me an Utopia Boot Disc VI1.1, but it didn't worked...

I just want to know how in the world I can "hack" my DC, or what I really need to play these games, the same ones my friend plays in his DC.

I wll be thankfull if someone could help me out.
