Which PS3 Serial Numbers are Backwards Compatible? An In-Depth Guide
Hey there! As a fellow tech head and retro gaming fan, I know how important backwards compatibility can be. Being able to play classic PS2 titles on modern hardware is a major benefit for PlayStation fans.
In this guide, we‘ll dive deep into identifying which PS3 models can play PS2 games. I‘ll share plenty of tips, research, and insider details so you can fully unlock your backwards compatible PS3‘s potential. Let‘s get started!
What is Backwards Compatibility and Why Does it Matter?
Backwards compatibility refers to a game console‘s ability to play titles from previous console generations. This allows you to enjoy your existing game library when upgrading to new systems.
For example, the PlayStation 2 could play original PlayStation (PS1) games in addition to PS2 titles. This meant PS1 owners could conveniently access their full catalog of games after upgrading.
Backwards compatibility provides a few major advantages:
- Preserves access to older games and libraries
- Allows comparing new and old games side-by-side
- Saves money by reducing re-purchasing of titles
- Enables games to be passed down through generations
- Allows older hardware to be retired while keeping games
When the PlayStation 3 originally launched, full hardware-based backwards compatibility with PS2 games was a major selling point. This influenced many gamers‘ decision to upgrade from the popular PS2.
However, Sony later removed PS2 backwards compatibility from newer PS3 models via firmware updates and hardware changes. Cost-cutting was cited as the reason.
As a result, only some PS3 systems retain native backwards compatibility with PS2 discs and digital purchases. For PS2 support on PS3, the specific model matters greatly.
Identifying a Backwards Compatible PS3 Model
With over a dozen PS3 models released over time, how can you easily determine PS2 compatibility? Here are a few quick ways:
Check the Model Number
On the back of the PS3, locate the model number sticker. Backwards compatible units generally start with "CECH-A" or "CECH-B". Some examples:
- CECHA01 (20GB Launch Model)
- CECHB01 (60GB Launch Model)
- CECHE01 (80GB MGS4 Bundle)
If it begins with "CECH-C" or later, it‘s likely non-compatible.
Count the USB Ports
Original backwards compatible PS3 consoles included four USB ports.
Later non-compatible models reduced this to just two USB ports.
If your PS3 has four USB ports, it most likely supports PS2 games.
Memory Card Slots
Backwards compatible PS3 models included memory card slots for PlayStation 1 and 2 memory cards.
Check the front of your console for two additional slots flanking the controller ports. Their presence indicates PS2 compatibility.
Test a PS2 Disc
Of course, the definitive way is to simply insert a PS2 game and see if the PS3 reads the disc and successfully boots into the game.
If you don‘t have any PS2 game discs on hand, you can pick up common titles like Grand Theft Auto: San Andreas for very cheap.
Now let‘s look at the specific PS3 models and their backwards compatibility in more detail.
Fully Hardware Backwards Compatible Models
These select PS3 models include the original Emotion Engine CPU chip used in the PS2:
PlayStation 3 20GB (CECHA01)
- Launch model released in 2006
- Fully compatible using PS2 hardware
- Extremely rare and expensive today
PlayStation 3 60GB (CECHA01 and CECHB01)
- Launch model with hard drive increase
- Retains full PS2 chipset compatibility
- Later revision switched to 65nm Cell CPU
These are the only PS3 consoles with 100% hardware-level backwards compatibility across all PS2 titles.
They can play any PS2 game released on disc or digitally with fast performance and no emulation glitches. Original memory cards also work.
These launch models are coveted by collectors due to their full compatibility and rarity. Prices for working units often exceed $200-300.
Models with Partial Software Emulation
Following the launch models, Sony removed the PS2‘s Emotion Engine CPU and replaced it with partial software emulation:
PlayStation 3 80GB (CECHE)
- MGS4 bundle edition
- First to drop PS2 hardware
- Can play ~95% of PS2 library via software emulation
PlayStation 3 Slim CECHG
- Early Slim models
- Compatibility rating around 90%
- Performance issues and glitches likely
PlayStation 3 Slim CECHH
- Later Slim models
- Further compatibility issues than CECHG
- Estimated 60-70% PS2 game library playable
While these can play many popular PS2 titles using Sony‘s software emulation, performance and compatibility issues are common.
Not all games work properly due to the complex PS2 architecture. Games may suffer from slow frame rates, visual glitches, freezes, and crashes.
PS2 Performance by Emulation Model
| PS3 Model | Emulation Type | Estimated Compatibility |
|---|---|---|
| CECHA/B | Hardware | 100% |
| CECHE | Software | 95% |
| CECHG | Software | 90% |
| CECHH | Software | 60-70% |
While still an option for PS2 gameplay, the partial software emulation models are less reliable than the full hardware models.
Non-Backwards Compatible Models
Starting in 2009, Sony released PS3 revisions that removed PS2 support entirely:
PlayStation 3 Slim 120GB (CECH-20xx)
- First Slim model with no PS2 support
- Saves costs by removing Emotion Engine
- Can only play PS1 games, not PS2
PlayStation 3 Super Slim (CECH-40xx)
- Drastic redesign released in 2012
- No backwards compatibility at all
- Will not play PS1 or PS2 games
All Other Late Slims
- Includes CECH-21xx, 25xx, etc
- Dropped PS2 support to cut costs
- Will not boot PS2 discs
These models eliminated PS2 backwards compatibility, likely due to the costs of retaining the feature.
If buying a used PS3, avoid these models if PS2 gameplay is a priority. Focus on the earlier hardware and software emulation models.
Maintaining Backwards Compatibility
If you own an original backwards compatible PS3, here are some tips on keeping PS2 support functional long-term:
Avoid Firmware Updates
Newer firmware disabled backwards compatibility. Stay on firmware 3.15 or earlier.
Consider Jailbreaking
Hacking can re-enable PS2 software emulation if accidentally updated.
Repair Any Overheating Issues
Heat damage can cause full backwards compatibility to fail.
Keep the System Clean
Prevent dust buildup which can cause overheating.
Proper maintenance and cooling is key for these aging consoles. The PS2 chipset and compatible motherboards are difficult to replace now.
The Growing Value of Backwards Compatible PS3s
Working backwards compatible PS3 consoles are becoming harder to find. As they continue to age and fail, prices for well-maintained units are increasing.
For example, the 20GB launch model (CECHA01) regularly sells for $400 and up if in good condition. Well over double the price of a standard Slim PS3.
Even damaged backwards compatible systems often sell for $100 or more just for spare parts. Replacement PS2-compatible motherboards are extremely rare.
For PlayStation collectors and enthusiasts who prioritize PS2 support, now is the time to invest in one of these systems before hardware failures thin their ranks.
Here‘s a quick look at the value trends:
PS3 Backwards Compatibility Premium Prices
| PS3 Model | Avg Used Price | Premium vs. Slim |
|---|---|---|
| CECHA01 | $400+ | 200%+ |
| CECHB01 | $250 | 100% |
| CECHE01 | $180 | 60% |
| CECHG01 | $130 | 30% |
Owning a working launch model with full compatibility could net a tidy profit down the road. These scarce systems should continue to appreciate as holy grails for PS2 support on modern TVs.
How Does PS3 Backwards Compatibility Compare to Other Consoles?
Sony wasn‘t alone in flipping back and forth on backwards compatibility last generation. How does PS3 compare?
Xbox 360
- Launched with ~50% compatibility for Original Xbox games
- Later models lost compatibility
- Requires hard drive for Xbox emulation
Wii
- Fully compatible with GameCube discs and controllers
- Later models removed GameCube ports
- Still played GameCube games via Memory Card slot
PlayStation 3
- Early models had near full PS2 compatibility
- Support gradually dropped each hardware revision
- Requires actual PS2 components for best performance
While no system remained fully backwards compatible through its entire lifespan, Nintendo‘s Wii had the least compromises.
Sony took an "all or nothing" approach by completely eliminating PS2 support after initial compatibility. This likely points to the challenges of emulating the complex PS2 architecture.
The Quest for Software PS2 Emulation on PS3
With Sony giving up on PS2 emulation in later PS3 models, homebrew hackers picked up the torch:
2007 – PS2Emu Proof of Concept
- First public PS2 emulator for PS3
- Minimal compatibility
- Basis for future projects
2010 – Official Sony PS2 Emulator Leaked
- Meant for internal testing
- Playable titles but glitches
- Sony forced it offline
2018 – PS2 Classics Emulator
- Plays ~30% of PS2 library
- Good performance on some titles
- Active project as of 2022
Although no software emulator achieves the compatibility or stability of real PS2 hardware, progress is being made.
Ideally Sony would release their internal emulator, but they remain protective of it. Homebrew coders tirelessly work on improving unofficial solutions for those desperate to play PS2 games on non-compatible PS3 models.
While software emulation on PS3 can‘t fully replace true PS2 hardware support, it offers a glimpse into what could be achievable. This cat-and-mouse game between Sony and hackers continues playing out.
Methods to Enable PS2 Backwards Compatibility on Any PS3
For those with non-compatible PS3 models, there are some complex methods that can potentially enable limited PS2 support:
Hardware Modding
- Installing PS2 chips from a donor system
- Very challenging – not for beginners
- Risk of console damage
Jailbreaking + Homebrew Emulation
- Uses software emulation
- Unofficial emulators have bugs
- Legal gray area
Buying a Backwards Compatible PS3
- Guaranteed compatibility
- Models with full PS2 hardware recommended
- Expensive due to scarcity
While modding and jailbreaking might seem appealing for free PS2 support, purchasing an older backwards compatible PS3 is the least risky option.
Attempting to hack PS2 functionality onto an unsupported system has downsides:
- Unpredictable stability and performance
- Can break other functions of the PS3
- Voided warranty if damaged
- Questionable legality
For most gamers, an official backwards compatible PS3 is the safest choice. The upfront cost saves endless frustration and tinkering down the road.
Maintaining Your Backwards Compatible PS3
Here are some handy tips if you‘re lucky enough to own an original backwards compatible PS3:
Keep Firmware Up-To-Date
Avoid updating past firmware 3.15. Newer versions disable PS2 support.
Replace the Thermal Paste
New paste keeps temperatures low preventing failure of aged components.
Clean Out Dust Buildup
Prevent overheating by removing accumulated dust from heatsinks and fans.
Consider Replacing the Fan
The original 15-blade fan is prone to wear. An aftermarket replacement ensures proper airflow.
Check for Signs of YLOD (Yellow Light of Death)
Overheating can damage chips needed for backwards compatibility.
Store Discs Properly
Keep your PS2 collection in good condition so the laser can read discs.
Test Discs Before Buying
