Ok les gars...

"from multiple people who bought the original copy of GTA SA : they checked it with different softwares such as Nero, Alcohol,... And it is now sure that this is a DVD5 game (single layer)... One even tried to make a backup of the game on a single layer DVD-ram with DVD Decrypter and played with no problem using this backup... I think that the question is now answered : the PARANOID version is the full final retail of the game, period."

Je suis trop paresseux pour traduire mais il me semble clair qu'il n'y a plus de doute : le jeux est sur support simple couche (DVD5) et la version Paranoid est bien la version finale !
