@blackshadow That's one of the more creative ways around piracy, but in order to taunt people for using pirate copies the system it is running on has to have some way to determine whether the copy is a counterfeit or not.
and in theory, measures like this can be bypassed with emulation.
All the files of a PS1 disc can be copied as shown in the video,
what your CD drive in your PC cannot do anything about, though is the information that tells the PS1 console whether the copy is legitimate or not which is on a separate track that is not accessible by common CD burner drives used in PC's.
and a Playstation 1 with a mod chip or an emulator such as PSX can get around this problem.
