I have successfully backed up many games and the only ones I seem to have a problem with are the games like Street Fighter Anniversary Collection and Midway's Arcade Treasures 2. I think that they are burned right because the games do boot up, but when I get to the screen to choose which game I want to play it locks up and gives me a black screen with rainbow colors on the right side. I burned them using dvd decrypter at 2x speed on philips dvd+rs and I am using the swap method with cd loader. I've been told to use dvdloader mode 3 as well but that didn't work for me. If someone has experienced this problem and fixed it please reply or if anyone has any extra suggestions.
