"don't repair sub channel data"

[Bl@de]

U will be able to copy psx games but only ones that re not protected (these tend to be older games). If u wish to make a 1:1 copy of a protected psx game u will need the dont repair subchannel.
U can however copy protected psx games by using cdrwin and patching the image file this will work for all protected psx games as long as there is a patch avaliable.
