What Does Backwards Compatible Mean? PS5, Xbox & Switch 2 Guide

Updated November 2026.

Backwards compatible means a new console can play games made for an older one, using the disc, cartridge or download you already own, without buying the game again. The PS5 plays almost every PS4 game, the Xbox Series X|S plays almost every Xbox One game plus a hand-picked list of Xbox 360 and original Xbox games, and the Switch 2 plays almost every Switch game.

Mostly.

There are catches: disc drives you might not have, accessories that don’t fit anymore, and a lot of stuff sold as “backwards compatibility” that’s really just selling you the game again. Here’s how it shakes out on each console.

What does “backwards compatible” mean?

In gaming, a console is backwards compatible (also written “backward compatible”, and sometimes called “back compat” or “reverse compatible”) when it can run software made for an earlier system. The term comes from tech in general: new hardware or software that still works with the old stuff. The opposite, forwards compatible, means old hardware that can handle newer software, which is rare in consoles.

The key word is your. Back in 2017, LevelSave’s James T. George argued that streaming an old game isn’t real backwards compatibility. Nine years later, he’s still right. The quick test:

Backwards compatible	Not backwards compatible (but often called it)
Your PS4 disc or download running on a PS5	A remaster or port you buy again (Mario Kart 8 Deluxe)
An Xbox 360 game you own running on an Xbox Series X	Streaming old games from a subscription (PlayStation Plus Premium)
Your Switch cartridge running on a Switch 2	Classic games inside a subscription library (Nintendo Switch Online)

Quick answer: what plays on what

Console	Plays your old games	Doesn’t play	Other ways to get older games
PS5 and PS5 Pro	PS4 games, disc and digital (all but a handful)	PS3, PS2 and PS1 discs	PS Plus Premium: PS1, PS2 and PSP classics to download, PS3 games by streaming
Xbox Series X\|S	Most Xbox One games, plus a fixed list of Xbox 360 and original Xbox games	Kinect games; 360 and original Xbox games not on the list	Disc to Digital (Xbox One and Series discs), Game Pass, the Microsoft Store
Nintendo Switch 2	Switch games, cartridge and digital (all but a small list)	Wii U, Wii and GameCube discs	Nintendo Switch Online + Expansion Pack, including GameCube classics

PlayStation 5: plays PS4, not PS3

PS4 games

Sony says the PS5 plays “the overwhelming majority of the 4,000+ PS4 games.” Its official list of PS4 games that do not run on PS5 is six titles long as of this writing:

Afro Samurai 2: Revenge of Kuma Volume One
Hitman Go: Definitive Edition
Just Deal With It!
Robinson: The Journey
Shadwen
We Sing

Sony notes the list can change. On the PlayStation Store, games that won’t run are marked “Playable on: PS4 only.” Some PS4 features are missing on PS5 too, such as the SHARE menu during PS4 gameplay and PS4 tournaments.

Discs, downloads and the Digital Edition

Digital PS4 games you bought are in your library and download straight to the PS5. You can move games and saves over from a PS4 by Wi-Fi data transfer, or play PS4 games directly from a USB drive.
PS4 discs work in any PS5 with a disc drive. Insert the disc (it may download an update) and keep it in the drive to play.
No disc drive? The original 2020 PS5 Digital Edition can’t play discs at all. The slimmer PS5 Digital Edition and the PS5 Pro ship without a drive but take Sony’s detachable Disc Drive, sold separately.
Upgrades: some PS4 games offer a PS5 version, sometimes free and sometimes paid. Saves carry over for many of these, but it’s up to each game.

Controllers, PS VR and Game Boost

PS4 games work with the DualSense or a DualShock 4. PS5 games need the DualSense.
Original PS VR games run on PS5 with the PS VR headset, the PlayStation Camera for PS4 and a free PlayStation Camera adaptor from Sony. PS VR2 doesn’t play original PS VR games.
Game Boost: select PS4 games run with a higher or smoother frame rate on PS5, and the PS5 Pro can push some further. It depends on the game and isn’t guaranteed.

What about PS3, PS2 and PS1?

Short answer: no. Sony says plainly that “PS5 consoles do not support PlayStation 3 discs,” and PS2 and PS1 discs are out too. The PS4 dropped disc back-compat back in 2013, and the PS5 did not bring it back. If you want to play older PlayStation games, you’ve got three options, and none of them is your old disc:

PlayStation Plus Premium (the top subscription tier) has a Classics Catalog of PS1, PS2 and PSP games you can download, plus PS3 games that are streaming-only. It’s a rotating library, not your own collection.
PS2 and PS1 classics you bought on PS4 are PS4 games, so they play on PS5 like any other PS4 game.
Remasters and remakes, which you buy again.

Xbox Series X|S: the best back-compat library for gamers

Xbox One games

Microsoft says “most Xbox One games are playable on Xbox Series X|S.” The one real exclusion is games that require Kinect, since the Series consoles don’t support it. See Microsoft’s backward compatibility page for anything else on its excluded list.

Xbox 360 and original Xbox games

This is where Xbox leaves everyone else behind – Microsoft actually gets it. Microsoft started bringing Xbox 360 games to the Xbox One in 2015 (we tried it at the time) and original Xbox games in 2017, and every one of them also runs on Series X|S. The list is fixed now: the final batch of 76 games arrived on November 15, 2021, when Microsoft said it had “reached the limit” of what it could add because of licensing, legal and technical constraints. So you get 632 of the 2,155 Xbox 360 games, plus several dozen original Xbox games. Not everything, but nobody else comes close (and they’re insulting your intelligence if they claim otherwise.)

Digital 360 games you bought on Xbox Live are in your library if they’re on the list.
360 and original Xbox discs work on the Series X disc drive for games on the list: insert the disc, the console downloads the game, and you keep the disc in to play.
The Series S has no disc drive, so it’s digital only.
Older games often run better: FPS Boost roughly doubles the frame rate on supported titles, Auto HDR adds HDR to games that predate it, and many get a resolution bump.
Smart Delivery games give you the Series X|S version for free if you own the Xbox One version.
25 Original Xbox games were also just made available on PC, with Microsoft undoubtedly planning to add more.

New in 2026: Disc to Digital

This one’s new, and it’s a good one : Xbox will now turn a lot of your discs into digital copies. Announced in August 2026 and opened to all players at the end of September after a test with Xbox Insiders, Disc to Digital is free and works like this: turn on your console (obviously,) sign in, insert a supported disc into any Xbox with a disc drive (an Xbox One or Xbox Series X), and launch the game. Your account gets a digital license for it, and the disc keeps working as it always has.

What qualifies: most Xbox One and Xbox Series X|S game discs, with Microsoft adding more over time. Not every disc is eligible, and Xbox 360 and original Xbox discs aren’t supported at all. You also may run into problems with older discs that have experienced disc rot or haven’t been stored as soundly.
What you get: the digital version, including Xbox Play Anywhere and Xbox Cloud Gaming where the game supports them. Claimed Xbox One games also play on an Xbox One.
Series S owners: the Series S has no disc drive, so you can’t claim a license on it, but a license you claim on another Xbox works on your Series S.
The catch: it’s one license per disc, and it’s tied to that disc. Microsoft says that if you lose, sell or give away the disc, access to the digital license “may be limited or revoked.” So don’t sell the disc Basically once someone else claims the license, you
Is my disc eligible? Put it in and see if the console offers you the license. Microsoft’s Disc to Digital support page has the details.

Nintendo Switch 2: plays Switch, with a few catches

Switch games

The Switch 2 (launched June 5, 2025) plays Switch games, both cartridges and downloads. When it launched, every Nintendo-made game it tested worked except Nintendo Labo Toy-Con 04: VR Kit, and only a small slice of the third-party library had problems. Nintendo keeps a list of games with known issues and has been fixing them through system updates, in batches, since launch. If you’re counting on an older indie game, check the list first.

Upgrades and Game-Key Cards

Nintendo Switch 2 Edition: select Switch games have a paid upgrade with better visuals, smoother frame rates and sometimes new content (Zelda: Breath of the Wild, Tears of the Kingdom, Super Mario Party Jamboree, Kirby and the Forgotten Land). Others, like Super Mario Odyssey and Pokemon Scarlet and Violet, get free updates.
Game-Key Cards are Switch 2 cartridges that hold a key rather than the game, which downloads when you first play. They’re a Switch 2 format, not a back-compat feature.

Controllers and accessories

Original Joy-Con and the Switch Pro Controller work with Switch games on Switch 2, except where a game needs something only Joy-Con 2 does, such as mouse controls. A few games need the original Joy-Con because of their IR camera or leg strap: 1-2-Switch, Everybody 1-2-Switch!, Game Builder Garage, Nintendo Switch Sports (Soccer Shoot-Out) and WarioWare: Move It!. Ring Fit Adventure needs an original Joy-Con in the Ring-Con, and the bigger Switch 2 doesn’t fit several Labo kits.

Wii U, Wii and GameCube

Nope. The Switch 2 has no disc drive, which James pointed out in 2017 about the original Switch. Many Wii U games came back as Switch ports (which you buy again), and Nintendo Switch Online + Expansion Pack includes a library of GameCube games that is exclusive to Switch 2.

PC: the one nobody talks about

PC never really had console generations, and that’s its trick. Games you bought on Steam, GOG or other stores stay in your library, and modern Windows runs most older PC games. Very old ones sometimes need a patch or a re-release (GOG sells many of these already fixed). Handhelds like the Steam Deck carry your Steam library with them, though not every game supports it. And, of course, if you’re privy to sail the high seas, PC opens up an impossibly endless number of opportunities.

A short history of backwards compatibility

Atari 7800 (1986): ran almost all Atari 2600 cartridges using the same chips, making it the first console with built-in backwards compatibility. Add-ons for the ColecoVision and Atari 5200 had played 2600 games a few years earlier.
Game Boy Color (1998) and Game Boy Advance (2001): the GBC played Game Boy games, and the GBA played both. The Nintendo DS and DS Lite played GBA cartridges (but not Game Boy or Game Boy Color), and the DSi dropped the slot.
PlayStation 2 (2000): played almost the whole PS1 library, accessories included.
Xbox 360 (2005): played a selection of original Xbox games through emulation.
PlayStation 3 (2006): the launch models had PS2 hardware inside. The European launch model used partial software emulation, and Sony removed PS2 support entirely from late 2007 models on. Every PS3 plays PS1 games.
Wii (2006): early models played GameCube discs and used GameCube controllers and memory cards. The 2011 redesign and the Wii Mini dropped it.
Wii U (2012): played Wii discs and accessories.
PS4 and Xbox One (2013): launched with no back-compat at all. Microsoft added Xbox 360 games in November 2015 and original Xbox games in October 2017. Sony never did, and we were not thrilled.

So who does it best?

Xbox wins and it isn’t even close. Microsoft went back and made hundreds of Xbox 360 and original Xbox games run on newer hardware, often better than they ever did, and now it’s turning discs into digital licenses for free. Nintendo did right by Switch owners, but if your shelf is full of Wii U and GameCube discs, the Switch 2 can’t help you. Sony covers the PS4 well and then stops: your PS3, PS2 and PS1 discs are stuck on the hardware they came with, and the official alternative is a subscription that rents some of them back to you.

What we’d want from the next generation is simple: if you bought it, it should keep working.

FAQ

What does backwards compatible mean?

It means a newer console can play games made for an older one, using the copy you already own (disc, cartridge or download) without buying it again.

Is the PS5 backwards compatible with PS3 games?

No. PS3 discs don’t work on PS5. Some PS3 games can be streamed with PlayStation Plus Premium, and some have PS4 or PS5 remasters.

Can the PS5 Digital Edition play PS4 games?

Yes, digital ones. For PS4 discs you need a disc drive: the newer Digital Edition and the PS5 Pro can add Sony’s detachable Disc Drive, but the original 2020 Digital Edition cannot.

Can the Xbox Series X play Xbox 360 discs?

Yes, if the game is on Microsoft’s backward compatibility list (632 Xbox 360 games). The console downloads the game, and the disc stays in to play. The Series S has no disc drive. Xbox 360 discs aren’t part of Disc to Digital, so they won’t turn into digital copies.

Can I turn my Xbox discs into digital games?

Yes, for most Xbox One and Xbox Series X|S discs, for free. Insert the disc into any Xbox with a disc drive (Xbox One or Series X) while signed in and launch the game to claim a digital license, which then also works on a Series S. It’s one license per disc and it stays tied to the disc, so selling or losing the disc can revoke it.
