Perhaps one of the most impressive facets of Valve’s Steam Deck is its exceptional price-to-performance relationship. Where you get a far greater game library to play than most systems of that price could muster. This is bolstered by the Steam Deck’s capacity to emulate almost all PS2 games as well. Let us show you how you can emulate these games on the Steam Deck in this guide.
Follow these steps to start playing PS2 games on your Steam Deck:

Guide to PS2 Emulation on the Steam Deck
The PS2 was one of the most prolific console systems to ever be released by Sony. It has a myriad of legendary game titles that have spawned billion-dollar franchises. So it’s no wonder that if you recently bought yourself a Steam Deck you would want to try and emulate some of those great games, to play in the palm of your hands.
If you’re looking to emulate PS2 games on your Steam Deck then you will have to download and install PCSX2, which is probably the most famous and widely used PS2 emulator available on the internet right now.
The emulator will allow you to play most PS2 games on your Steam Deck, and if there are any exceptions then those will be listed in their compatibility list on their website, which you can visit and find out more about the emulator itself. For now, let’s dive into how to get PCSX2 on your Steam Deck.
How to download and Install the PCSX2 Emulator on Your Steam Deck?
Before you can begin to play PS2 games on your Steam Deck you will need to download the emulator onto it. You can do this by first switching your Steam Deck from Game Mode to Desktop Mode, as you will then have access to more applications that replicate a Windows experience.
Switch Steam Deck from Game Mode to Desktop Mode
- Boot up your Steam Deck, and you should automatically start in Gaming Mode
- Hold Down the Power Button, whilst you’re still in Gaming Mode
- You will notice that a Menu pops up at the center of the screen
- Navigate to and Select the “Switch to Desktop Mode” option from the Menu
- Your screen should now be set to Loading
- Upon Completion of the Loading process, you should now be able to access Desktop Mode
Install PCSX2 on Your Steam Deck
You can only download the PCSX2 Emulator application from the Discover application that can be found on the taskbar of the Steam Deck’s Desktop Mode. So once you’ve entered Desktop Mode simply follow these steps:
- Open the Discover Store Application
- Navigate to and Open the Application option provided on the left-side Menu.
- Next, Locate and Select Games from the Left-side Menu
- Click on the Emulator option in the Games genre section
- Scroll down the list of emulators you can download and locate PCSX2
- Simply download the emulator and wait for it to install
And that’s pretty much it folks. Now you’ll have access to a PS2 emulator on your Steam Deck. However, many steps still remain to be completed to ensure that your emulator works to the best of its ability on your Steam Deck.
Replace the PAD.ini File in the PCSX2 Configure Folder
Although we would like to say that as soon as you finish downloading your PCSX2 emulator you will now be able to play PS2 games, that is just simply not the case. The problem is that PCSX2 cannot detect the Steam Deck’s controls as valid inputs natively. And thus requires additional files to do so.
This is where our PAD.ini file comes in, which will be provided to you. Its major purpose is to provide the necessary information to your emulator to allow it to read inputs from the Steam Deck, and give you as close to a handheld PS2 console experience as possible.
So if you’re willing to ensure your experience is as smooth as it can be then follow these steps:
- Download the PAD.ini file from this link
- The files name will be different upon download, please ensure to rename the file to “PAD.ini”
- Now that you have the file, simply Copy the file and paste it into the following storage address
- Paste the file within this folder and Overwrite the existing file.
- Confirm and close the PCSX2 folders.
Your PCSX2 emulator should now be able to recognize the inputs of the Steam Deck and will be able to easily map its button layout according to that available on the Steam Deck itself. This is incredibly helpful and should not be a step that is missed.
Download BIOS Files
Any PS2 emulator will not work if you do not download and install the PlayStation 2’s BIOS files. These are essential system files that are coded into the console that allows many video games to launch in the first place, or even work at all.
The BIOS files are thus entirely necessary if you wish to play PS2 games on your Steam Deck. However, we, unfortunately, cannot link websites where the BIOS files are available. Instead, we urge you to Google “PS2 BIOS for PSX2” to find the necessary BIOS for your emulating requirements.
Once you have the files from downloading them off the internet, you need to place them into the BIOS folder that was created when the installation of your PCSX2 was complete. Simply put the files into the additional BIOS folder, and this step will be complete as well.
Important PCSX2 Configurations For Smooth Gameplay
There are several configuration options that PCSX2 provides you that can help smoothen a lot of the issues that might arise out of trying to emulate old PS2 games. We’ve listed here several of the options that we think can make a great difference, and recommend that you configure your PCSX2 accordingly.
- Boot up your PCSX2 application from your Desktop or Applications menu on your Steam Deck
- Next, Close the info screen that opens along with your PCSX2 window. This window can cause problems to your system later on and might cause difficulties to run certain games.
- Once you’re done with that head on over to the PCSX2 application and Select the options System> Game Settings> Enable Widescreen Patches
- Next, we suggest that you move on to the Config menu and click on it
- Navigate to the Speedhacks section
- Enable MTVU
Finally, we’ll recommend making a few final changes to the overall performance of your Steam Deck while it emulates PCSX2. Ensure that you go to the GS Window option and make the following changes shown in the table provided below. Lastly, enable Hacks in the Graphics Settings section.
