Since the end of 1998 Sony introduced the first protected PlayStation games in Japan ([PoPoRogue](https://consolecopyworld.com/psx/psx_poporogue.shtml)). They added extra code, called LibCrypt, could detect if a Mod-Chip was being used. When it detected it then game could not be played.
About 6 months later the LibCrypt protection was also used on European PAL games ([Medievil](https://consolecopyworld.com/psx/psx_medievil.shtml)) and now also US games are being protected.
The LibCrypt protection uses a Digital ID (16 bit key), which is stored in the SubChannel of a CD-ROM. Until now there have been 4 different protection schemes: LC1, LC2, LC3 & LC4
Here is an overview of all currently Protected PlayStation Games:
Protected Games [UK/PAL]](https://consolecopyworld.com/psx/psx_protected_games_uk.shtml)
Protected Games [JAP/NTSC]](https://consolecopyworld.com/psx/psx_protected_games_jap.shtml)
Protected Games [US/NTSC]](https://consolecopyworld.com/psx/psx_protected_games_us.shtml)
