This was a feature from the SCPH7000 models and up, and introduced a visualizer that appeared in time with the music by pressing SELECT on the controller. Or maybe not, since the NTSC versions used the PAL design albeit with different icons, you can briefly see the Soundscope effect in the BIOS before it fades to a black background SCPH102 (Europe PSone redesign) Seems like Sony wanted to unify the BIOS designs worldwide and change Europe to look like the US/Japanese versions SCPH101 (US PSone redesign) This model introduced SoundScope, this BIOS would remain the same for the SCPH9001 models SCPH7002 (Europe) No visible difference from the 1002? SCPH7001 (US)

Sony would continue to revise each hardware SCPH5002 (Europe) Model numbers would be synchronized with the 500x series. Japans SCPH3000 is equal to our 1001/1002, with their 1000 being a different revision with a buggy GPU. Also the Europe Cd player can have different sound effect applied to it, which I couldn’t find in the NTSC BIOS? SCPH3000 (Japan) This is the BIOS I remember growing up with. In PAL-land we got this menu instead, using icons and symbols instead of text due to the different languages used in Europe and to reduce the ROM space.

Initial BIOS version for the NTSC lands SCPH1001 (Revised US Model)Ī revised version of the US model, the option colour has slightly changed SCPH1002 (Europe Launch model) The very first BIOS version, this one has a different cursor appearance and the CD player cannot be accessed unless an audio CD is in the drive. Like the hardware, the BIOS went through various revisions and designs which we will look at. Not all games provided a way to manage the memory card so the BIOS was often used for this purpose. The purpose of the BIOS for the PlayStation was to provide an interface for the end user to manage their memory cards and the option to play an audio CD and was automatically displayed when the console was turned on without a disc inserted.
