Om du mener i forbindelse med onlinespilling så sier wikipedia dette:
All newer online PS2 games (since 2003) are protected by the Dynamic Network Authentication System (DNAS). The purpose of this system is to prevent piracy and online cheating. DNAS will prevent games from being played online if they are determined to be pirated copies, or if they have been modified.
Jeg aner ikke om det finnes noen vei rundt akkurat det, men det er vel uansett ikke lov å diskutere her.
