Hi Folks,
Well, with this last message I conclude that if anybody here is using the PS2 Slim line and swap magic 3.3 or 3.6 version, the backup game just will not work, because the CDloader/DVDloader does not work with the slim line because of the sensors, so We can not Refresh the TOC since the sensors are always deactivaded when We use the slim tool, ghost switch.
I remember that the only way is install an external switch to turn on/off the sensors, is the only way to do Refresh the TOC.
Well, we have to live with this now...

... and play and take care of the original disk).
Thank you all again for the great help.
