recently I backed up dark chronicle and resident evil code veronica. The 1st game was running just fine until the time I had to face the final bosses. I used Princo(thrown it already) and next e-Proformance. Both DVD-Rs freze! The 2nd game stops loading just before the beggining of the 2nd part(Antartica). Is it the quality of the disks or the original DVDs? modchip matrix (mxl I think) PS2 V9(I think). please help.
