New kind of protection for PSX games????

[Rogue Trader]

In the computermagazine I buy each month there was a article of PSX-games. In it they talk of a new kind of "protection" for the new games that acts like a virus. Every time you play your backup it ads faults to the game and in the end it becomes unplayable.
Has anyone else hear about it or seen it???
I haven't but I only have backups for PS1.
