Short answer: The official PlayStation information reviewed for PS5 covers backward compatibility with PS4 games, not original PS2 discs. For playing discs from your PS2 collection, PCSX2 on a compatible Windows, Linux, or macOS computer is the documented route: it can start a disc directly, but the project recommends dumping the disc to an ISO and requires a BIOS dump from a legitimately owned PS2 console.
Can I play PS2 discs on PS5?
PlayStation’s current PS5 ecosystem information explains playing PS4 titles on PS5 and handling PS4 game upgrades. It does not list original PS2 discs as playable media. The most accurate consumer-facing answer is therefore: the official PS5 backward-compatibility information reviewed does not document PS2 disc playback. That is a statement about the published support scope, not proof that every possible hardware modification, unofficial application, or future feature is technically impossible.

PlayStation’s March 18, 2020 hardware article described launch-era backward compatibility in terms of the PS4 catalog. It said the overwhelming majority of more than 4,000 PS4 titles were expected to work on PS5. That figure refers to PS4 games, not PS2 games, and the article is historical rather than a current, exhaustive feature list. You can read the article at PlayStation Blog. The current PS4/PS5 ecosystem page is available at PlayStation.com.
Consequently, putting a PS2 DVD into a standard PS5 is not an officially documented way to launch that disc. A PS5 can use supported PS4 physical games and, where offered, PS4-to-PS5 upgrades; that is a different compatibility program from reading a PS2 game disc.

Can PCSX2 play PS2 discs?
Yes. PCSX2 is a free, open-source PlayStation 2 emulator for Windows, Linux, and macOS. Its FAQ documents a direct-disc route: after setup, choose System > Start Disc and select the computer’s optical drive. The project also warns that some games can run with speed problems from a PC drive because the drive does not keep spinning in the same way a PS2 does. Its stated recommendation is exact: “It is recommended to instead dump your games to ISO images.” See the PCSX2 FAQ.
An ISO is a disc image stored on your computer. Once you have made a good dump from your own disc, PCSX2 can load the image without repeatedly reading the optical media. This usually gives a more predictable starting point and avoids the drive-speed issue described in the FAQ, although the game can still have emulator-specific compatibility issues.
PS5 and PCSX2 compared
| Question | PS5 | PCSX2 on PC |
|---|---|---|
| Official support for original PS2 discs | Not documented in the PlayStation PS5 support information reviewed. | Direct disc launch is documented by the PCSX2 project. |
| What the published compatibility information covers | PS4 games and PS4-to-PS5 upgrades; the 2020 launch article discussed more than 4,000 PS4 titles. | PS2 emulation, with title-by-title results that can vary by game and computer. |
| Use of your physical PS2 disc | No documented PS2-disc playback path. | Use System > Start Disc, or dump the disc to an ISO first. |
| Required setup | Normal PS5 system and a supported PS4 game workflow. | PCSX2 installation, a BIOS dump from a legitimately owned PS2, and first-run setup. |
| Computer requirements | Not applicable. | A supported 64-bit operating system, compatible CPU and graphics APIs, at least two physical CPU cores with simultaneous multithreading, and the project’s stated minimum memory tier of 8 GB RAM. |
| Optical drive | Does not create a documented PS2-disc feature. | Needed only if the PC must read or dump a physical disc; a standard drive supporting both DVD and CD media is suitable. |
| Compatibility certainty | PS2 disc support is not listed in the reviewed documentation. | Check the current PCSX2 compatibility information for the exact title; no game should be treated as guaranteed without checking its entry. |
| Ownership requirements | Use the game formats and licenses supported by PlayStation. | Dump the BIOS from your own legitimately owned PS2 and use discs or images you are entitled to use. |
What you need to run PCSX2
A compatible computer
PCSX2’s FAQ lists a minimum tier that includes a 64-bit supported operating system, SSE4.1 CPU support, two physical CPU cores with simultaneous multithreading, supported graphics APIs, and 8 GB of RAM. The recommended tier is higher. These are project requirements, not a promise that every game will run at full speed: game complexity, graphics settings, drivers, and the particular computer all affect results. Requirements can change as PCSX2 develops, so consult the project’s current documentation before upgrading hardware.
PCSX2 supports Windows, Linux, and macOS. Install the current build appropriate for your operating system, then let its first-run wizard establish the folders and basic settings. The project’s README and documentation are at github.com/PCSX2/pcsx2.
A BIOS dump from your own PS2
PCSX2 does not replace the console BIOS with a downloadable file. Its setup instructions require you to extract the BIOS from a legitimately owned PlayStation 2. The FAQ states: “First, you must dump your PlayStation 2 console’s BIOS using the BIOS dumper.” You then copy the resulting BIOS files to the computer and select them in the first-time setup wizard. Do not download a BIOS from an unofficial archive or imply that the emulator supplies one.
Your game media
You can begin with a physical PS2 game disc from your collection. PCSX2’s disc documentation explains that PS2 games are DVD or CD media and that a standard optical drive supporting both formats can read or dump them. A built-in drive is sufficient; if your computer has none, an external USB DVD/CD drive is only a conditional purchase for reading the media. Verify that the drive supports DVD and CD discs and works with your operating system.

The PCSX2 project README links to its compatibility list and reports more than 2,500 titles tested. The opened project page does not attach a publication year to that count, so treat it as a project-maintained figure rather than a permanent total. Before spending time troubleshooting, search the current list for the exact game, region or release where relevant, and read notes about graphical errors, freezes, speed, or required settings. A result for one title does not establish that another title will behave the same way.
How to set up PCSX2 with a PS2 disc
- Check the game first. Open the current compatibility information linked from the PCSX2 README. Record any known notes for your exact title instead of assuming that a broadly similar game will work.
- Install PCSX2. Download the current release for Windows, Linux, or macOS from the project’s official distribution channels and complete the normal installation for your operating system.
- Dump your PS2 BIOS. Use the project’s BIOS-dumping process on a legitimately owned console. Copy the dump to the computer when instructed. PCSX2 cannot complete a normal first-time configuration without a usable BIOS file.
- Run the first-time wizard. Choose the BIOS file, select language and other basic options, and allow PCSX2 to create or confirm its user folders. If the wizard cannot see the BIOS, check that the files were copied to the folder selected in the wizard and that they are readable.
- Insert the disc. Put the PS2 DVD or CD in a drive that supports that media type. Wait for the operating system to recognize the disc before launching it.
- Start the disc. In PCSX2, choose System > Start Disc, select the optical drive, and begin the game. This is the project-documented direct-disc procedure.
- Watch for drive-related speed problems. If the game stutters, slows down, or behaves inconsistently while the drive is reading, stop the session and make an ISO dump instead. The FAQ specifically recommends ISO images because some games do not perform well when the PC drive is used directly.
How to dump a PS2 disc to an ISO
ISO dumping is the preferred workflow when you want repeatable loading or your optical drive causes speed problems. The exact buttons depend on the disc-imaging application and operating system, so use a reputable desktop disc tool that can read PS2 DVD and CD media. PCSX2’s official guide is Dumping Discs.
- Insert the original PS2 disc into a standard DVD/CD optical drive.
- In the disc-imaging application, select the physical drive and choose an image format that preserves the disc contents. Save the image to a drive with enough free space.
- Allow the read operation to finish without suspending the computer or ejecting the disc.
- Keep the original disc available while you verify the image. If the dump is incomplete or damaged, PCSX2 may freeze at a loading screen or fail to boot.
- In PCSX2, add or select the folder containing the ISO, then launch the image through the normal game browser or system menu.
A successful dump is not the same as a compatibility guarantee. It only confirms that PCSX2 has a complete image to read; the emulator still has to reproduce that particular game’s behavior.
Performance: what can vary and why
Disc versus ISO behavior
Direct-disc play depends on the optical drive’s response and the way a particular game requests data. The PCSX2 FAQ says some games encounter speed problems because a PC drive does not keep spinning as a PS2 drive does. An ISO removes the repeated physical-media access from the play session, which is why the project recommends it.
Game-specific emulation
PCSX2 emulates a console rather than converting every game into a native PC program. A powerful computer can still encounter a title-specific bug, while a less powerful computer may run a simpler title acceptably. Use the compatibility list’s current notes for the exact game and treat labels or user reports as guidance, not a universal promise.

Hardware and settings
The minimum requirements are a starting point. CPU instruction support, physical cores, graphics API support, RAM, drivers, resolution, enhancement settings, and the operating system can all affect speed or visual accuracy. If a game is slow, first compare your system with the current PCSX2 requirements and the title’s compatibility notes before changing many settings at once. Change one setting, retest the same scene, and keep a record so you can undo an unsuccessful change.

PCSX2 says no BIOS is available
- Confirm that you completed a BIOS dump from your own PS2.
- Copy the dump into the directory selected by the first-run wizard.
- Reopen the BIOS selector and choose the correct file rather than a parent folder containing unrelated files.
- Do not substitute a downloaded BIOS; the project’s requirement is a dump from a legitimately owned console.
The disc is not detected
- Check that the drive supports the disc’s format: PS2 media can be DVD or CD.
- Confirm that the operating system itself can see the drive and read the disc.
- If the computer has no optical drive, connect a standard external USB DVD/CD drive and verify its operating-system support.
- Use an ISO dump instead of direct-disc launch if the drive repeatedly loses the disc or produces read errors.
The game freezes at a loading screen
- Recheck the title in the current PCSX2 compatibility list.
- Redump the disc; the project’s disc guide warns that a bad dump can cause loading-screen freezes.
- Compare the ISO’s size and read result with the disc-imaging tool’s verification information.
- Test the ISO rather than the physical disc to rule out drive-speed or read-timing problems.
The game runs slowly or audio breaks up
- If you are using a disc, create and test an ISO because direct optical-drive access can cause speed problems.
- Compare your CPU, graphics support, RAM, and operating system with PCSX2’s current minimum and recommended requirements.
- Look up the exact title for known issues before assuming the computer is defective.
- Return experimental graphics changes to defaults if they introduce new glitches, then alter one setting at a time.
Which route should you choose?
Choose the PS5 route when your game is a supported PS4 title
If the game you want is a PS4 game supported by PS5, the console route is simpler: use the supported PS4 disc or digital entitlement and follow PlayStation’s upgrade or compatibility instructions. That convenience does not extend, in the reviewed official documentation, to inserting an original PS2 disc.
Choose PCSX2 when you want to use original PS2 media
PCSX2 is the practical documented option when your goal is to play from a PS2 disc or a dump made from that disc. It accepts the setup work—compatible computer, BIOS dump, emulator configuration, and title-specific checking—in exchange for access to a broad PS2 library on modern operating systems.

Pick the symptom - the matching free tool is one click away.
Use direct-disc mode only when it behaves well
Direct-disc launch is useful if you already have a working optical drive and want to start quickly. Switch to an ISO when the game has speed problems, the drive is noisy or unreliable, or you want to avoid repeated physical reads. Keep the original disc as the source of the image and retain it for verification.
Do not buy hardware before checking your setup
You may already have everything needed: a compatible computer, an optical drive, your PS2, and your game disc. An external drive is relevant only when the PC cannot read DVD/CD media. A newer or more expensive computer is not automatically the answer to a title-specific compatibility problem, so check PCSX2’s current requirements and compatibility notes first.
Bottom line for PS2 disc owners
For the PS5, the defensible answer is that Sony’s published PS5 compatibility information reviewed here covers PS4 games and does not list original PS2 discs. For a PS2 disc you own, PCSX2 documents both System > Start Disc and the preferred ISO workflow. Plan on dumping your own BIOS, using a compatible 64-bit computer, checking the exact game in the current compatibility list, and making an ISO when direct optical-drive play causes speed or loading problems.
