NTSC-U is the North American model of the console in which only North American console firmware is usable. It mainly includes these two models: scph1001.bin, scph5501.bin. The SCPH-1001 firmware is associated with earlier versions of consoles in the USA and Canada region. And the other scph5501.bin is used in the modern version or later released version of PS1 NTSC-U. Many emulators recognize one or both versions, but the compatibility of the games depends on the specific emulator and core.

NTSC-J is the version associated with the consoles of Japan and the Asian region. It has its own NTSC-J software. The common firmware file in the console of the Japan region is scph5500.bin. The consoles of this region have different game compatibility than North American or other European consoles due to regional licensing checks and video-system differences. This version is useful when playing original Japanese releases or Japan-exclusive titles.

The video system in the consoles of the European region uses PAL software. The common file names for this region include scph5502.bin,scph7002.bin,scph7502.bin. Scph5502.bin is mainly associated with older versions of the console, while scph7002.bin and scph7502.bin are the same, but they are files for the revised version of the console. Almost all consoles in the European region have PAL firmware for better compatibility with European-region licensed games. If you primarily play European PS1 games, use PAL firmware.

The asian region console mainly uses the scph7003.bin file, but this is not the universal bios for PS1 in asia and it is not compatible for all games. This is because Asian consoles don’t have any regional firmware files like PAL and NTSC. That is why some use the Japanese firmware, and some emulators and games are compatible on  scph7003.bin file. The consoles in the Asian market are associated with the SCPH-xxx3 model family.

What Is the Difference Between NTSC and PAL?

  • NTSC and PAL are the video systems for different games in different regions like the USA, Japan, and European countries. They determine the number of picture lines, refresh rate, color encoding, and how images appear on the screen in different models of consoles in different regions. The major difference between NTSC and PAL is not that one BIOS may be better than the other. They represent different regional standards used by the original PlayStation hardware and games.
  • The regional difference can affect how games are displayed. For example, the current Beetle PSX core reports approximately 59.8 FPS for NTSC content and 49.8 FPS for PAL content. This does not mean that if you put the BIOS of NTSC in your PAL model,  you will get 60 FPS. The best policy and safe way is to match the BIOS of your region in the emulator so you will not get any errors during the games.

How to dump the BIOS PS1 from the Console?

Dumping the files from your own console is the best and safest way to get the firmware files of the model because Playstation1 BIOS is copyrighted software owned by Sony. So downloading it from different websites may be risky. If you don’t know how to dump these files from the PS, then follow the steps given below:

Firstly, identify the model of your console because, as you know, different models and region consoles have different firmware bios such as SCPH-5501 for North America and SCPH-5502 for Europe.

Unlike PS2, which has the FreeMcBoot or FreeDVDBoot extraction method, PS1 doesn’t have this. You have an appropriate extraction method; the common options are Hardware-based extraction, Console-based software method, and Chip-reading method.

Depending on your extraction method, you need compatible homebrew software or may be the storage device, or additional hardware. Now follow the instructions according to the model of your console.

Now use the trusted software that is designed for extraction of firmware for PS1. After extraction, save the files to your console or to the storage device.

Now transfer the field from your storage device to your computer and then check whether the files are completely extracted, you can check the version on checksum; if it matches, then the files are complete.

Now put the files in the BIOS directory of the emulator you are using, mainly DuckStation or a compatible RetroArch core. Then your emulator will scan and recognize the files for the configuration of games.

How to Add BIOS to DuckStation ( Windows PC )

Playing games on your Windows device through DuckStation is quite easy. You have to follow the steps accurately, and you have to provide the correct BIOS directory in DuckStation. The method is explained below:

Firstly, dump the files from your console; the common file names include scph5500.bin — Japan, scph5501.bin — USA, and scph5502.bin — Europe. Make sure to do this step accurately because it is the most important step.

To open the files folder in DuckStation, follow this path: Tools → Open Data Directory. This is the place where DuckStation saves or stores the firmware files. The location for this folder will look like this:

%LOCALAPPDATA%\DuckStation\bios

  1. Locate your PS1 BIOS file on your computer and copy the file.
  2. Then paste them directly in the bios folder of DuckStation.
  3. Make sure to put the file in the correct directory; don’t put it into any other subfolder.

Open the directory and copy the files, and then store them in your pc or storage device. For Windows, the folder path will look like this:

RetroArch/System/scph5500.bin or scph5501.bin or scph5502.bin.

  1. Open RetroArch.
  2. Then go to Online Updater → Core Downloader.
