PS2 DVD Backup

[md_mushroom]

H, ps2 is version 5, asked mate who chipped it, he said that the laser wasn't re-calibrated in n e way, ps2 just taken apart, modified and put back, if there was a problem with the modifying, would the ps2 not boot up n e games at all, or is there a certain part of the chipping that could affect different cd/dvd media ?? Yes, cdr backups - Robot Wars and Crazy Taxi.

Many Thanx
