The Sony PlayStation console is a home video game console that started a wave of new video game technology in the middle part of the 1990s. The PlayStation was released in various regions, and each region had its own specific console identification. Much like DVD players, PlayStation consoles are region locked. This means the PlayStation console of a specific region can only play games from that region. The part of the console that keeps these restrictions is called the BIOS. BIOS files can be copied from the console to a computer where they can be used to play PlayStation games on computers.
All Sony PlayStation consoles that were sold in North America came with the same BIOS file. Pulling the file directly from the system will give you a file name of "SCPH1001.BIN." When using an emulator to run your PlayStation games on your Linux, Mac OS X or Windows computer, you need to use this file in order to play American PlayStation games. However, you will need to dump the BIOS file directly from your PlayStation if you plan on playing your PlayStation games via a computer legally.
Like other Sony PlayStation systems, the Japanese PlayStation console will only play games from the region it was made for. People dumping the BIOS from their systems will get a resulting file named "SCPH1000.BIN." The Japanese PlayStation console was the first PlayStation console released. The four numbers at the end of the BIOS file name coincide with the systems age. The lowest BIOS number signifies the oldest system.
The final BIOS file that your PlayStation might use is that of the European Sony PlayStation console. The BIOS file that is included with the Sony PlayStation's European console used the file name "SCPH7502.BIN." For those living in Europe or who have a European PlayStation console, this is the BIOS file you will need to play your PlayStation games on your computer. Europe.
With the ever-ongoing copyright infringement lawsuits being delivered to many people's doorsteps, game console makers have included the distribution of their system's BIOS files on the Internet illegal as well. The BIOS file includes data created by and used with each manufacturer's consoles. However, courts ruled that dumping the BIOS from a system that a consumer owns for personal use is legal, and they can keep that BIOS file on their computer for as long as they own the PlayStation console.
