Sony decided to buy the emulator and disabled it, although older versions of the emulator can be located on the internet.
As a result, Sony filed a case against Connectix, because the competition of VGS made it a threat to Sony. The ability to run most games that were only played in PS led to increased popularity of VGS emulator. Besides, VGS allows you to play most PS games. Apart from enabling you to run PlayStation games in your windows or Mac PC, VGS emulator library features many good games. Initially, VGS emulator was made for Mac, but it was later updated to accommodate windows PC. Connectix is the developer of VGS emulator.
