Copying "NGT US Open Tennis"
 

I wanted to make a backup of the PS2-Game "NGT US Open Tennis" and it didn´t work. I tried it with Clone-Cd and Nero, but when I started with AR2 the screen shows "Invalid CD". Does anyone else have problems with the game?

(PS: I use the Neokey Chip)

what media are you using? have you made backups using the same media that work?
