PS2 BIOS Steam Deck – how to emulate PS2 on your Deck

Are you interested in emulating the PlayStation 2 on the Steam Deck? Let’s start with the bios.

There are a lot of things you can do with the Steam Deck. The best emulators list can already give you some ideas. It’s not always easy to set them up, so let’s take a look at how to install the PS2 BIOS on Steam Deck.

PlayStation 2 was one of the most popular consoles of its time and perhaps ever. Many different game titles were available on the Sony system, some of which are still in existence today (God of War, for instance). With the Steam Deck, this is one of those systems you’d definitely want to always have in your hand.

The purpose of this guide is to explain how to set up the PlayStation 2 emulator and how to install the PS2 BIOS.

Installing the PS2 BIOS on the Steam Deck

To access PS2 emulation on the Steam Deck, you need to install the BIOS, which is one of the necessary steps. To boot up the console, these files are required.

We are unable to link to any websites that carry the required files, but a quick search on Google should be able to help you find them.

The PSX2 emulator must be installed on your Deck once you have downloaded the files. An emulator will create several folders on your portable console, including one called “BIOS”. Place all the files you’ve downloaded from the internet in the folder, and you’re done.

  • Install it with the blue icon, then configure the “Pad.ini” file to be able to control PlayStation 2 games without any problems;
  • Install the BIOS in the mentioned folder at this time;
  • As soon as you add the emulator to your Deck, it will be ready to play

In addition to these basic steps, you will want to configure the emulator to suit your tastes and ensure it runs smoothly after downloading. It is not the easiest process, but with a little bit of trial and error, you will soon be playing your favourite PlayStation 2 classics.
