The BIOS (Basic Input Output System) of any computing device is the coding it relies on to control data flow between the microprocessor and its various other devices. However, when you use an emulator, you will have access to all the games the old Playstations had at their disposal. Playstation released the Playstation Classic 2018 for enthusiasts to play old games on an actual Playstation, but it only allowed you to play 20 games on it. The Playstation gained a lot of popularity since it was easy to program for and it had a pretty good hardware system for the time period with a whole 1 MB of video RAM. The first PSX emulators were developed in the mid-90s right after the first Playstation was released. There are PSX emulators for a wide variety of operating systems such as Linux, Windows, Android, and MacOS. PSX emulators were developed in order to allow Playstation aficionados to play their favourite PSX games on their native personal computers.
