Hacking cannot read disc error during the game....

[todesto]

Just as titled....
I have back up of Mario Power Tennis (PAL) version playing in NTSC system (USA) with NTSC TV with forced NTSC backup launcher.
Game loads fine, plays fine, then sometimes in the middle of the game, screen shows cannot read disc...error...
If the game doesn't load at all at first, I would have better idea but I am completely lost in this case....

Anyone have idea why? If so, can this be fixed?

Thanks in advance.

Well, its maybe just what is says a disc read error.
suggestions:

Take other discs
burn slower speed
backup again.
