Compatibility prob with some CD's and writers ??

[Cabral]

Well bezzaxx, truth is that my friend came over my place with a few of his copies games.

Guess what : they all boot on my PSX. So its not my PSX laser or my modchip.

Tonight or tomorrow, I'll try exchanging my LG writer for a HP or a Yamaha. It I still can't copy my games after that, I'll be desperate.

ANY MORE IDEAS ON WHAT IT COULD BE ???
