Hi there! I have an unmodded ps2 (slim one), and my Champions of Norrath game doesn't work anymore. I think it's too scratched or something. It goes up to the first loading screen (before even starting the game) and it never starts. Do you think a backup copy could help me skip the scratched sectors? (Swapping the original with a backup when the game hangs up, or something?). Any help would be greatly appreciated! Thanks beforehand!
