It is imperative to state that was a legally gray tool. The software itself did not circumvent protection; it merely facilitated the user’s ability to do so. Under the DMCA (Digital Millennium Copyright Act) in the US and the EUCD in Europe, creating a backup copy of a disc that requires bypassing copy protection is illegal, even if you own the original.

Game Copy Pro V 2.73 is a software tool designed to create backup copies of video games. It allows users to make copies of their games, which can be useful for preserving their gaming library, playing games on different devices, or in case the original game is lost or damaged.

V 2.73 was the last build before the "Cat and Mouse" game became unwinnable for consumer software. Later protections (StarForce 3/4, SecuROM PAE) required firmware-level hacks on DVD drives, which V 2.73 could not handle. But for the golden era of PC gaming (Half-Life 2, Doom 3, Far Cry, The Sims 2), this version was perfect.
