AetherSX2 Game Compatibility: What Actually Determines It
There’s no official AetherSX2 compatibility list rating specific PS2 titles. What actually determines whether a game runs well comes down to a handful of variables you can check yourself, and this page walks through what they are.
Is There an Official AetherSX2 Compatibility List?
No. AetherSX2 has never published its own database rating individual games.
That’s different from PCSX2, the desktop emulator AetherSX2 is built on, which does maintain one. We’ll get to why that database doesn’t transfer directly.
Why Does Compatibility Vary by Game?
AetherSX2’s own documentation explains this in general terms: different games have very different hardware requirements, based on how heavily they use the PS2’s various components. Some titles lean hard on the graphics chip, others on the CPU, and a few stress parts of the hardware that are simply harder to emulate accurately.
That’s the app’s own explanation for why one game can run great while another struggles on the same phone.
Does PCSX2’s Compatibility Database Apply to AetherSX2?
Not directly, and this is worth understanding before you go looking for a shortcut. PCSX2’s official database rates a large share of PS2 games as playable or better, but that number reflects continuous desktop development.
AetherSX2 is based on a snapshot of PCSX2 from before official development stopped. Improvements made to PCSX2 after that point were never inherited by AetherSX2. On top of that, PCSX2’s testing runs on desktop GPUs, which don’t share the same limitations as the mobile chips inside your phone.
Think of PCSX2’s database as background context on how mature the underlying emulation logic is, not as a guarantee for how any specific game will behave on AetherSX2 and your device.
What Affects Whether a Game Runs Well on Your Device?
Game Complexity
Some PS2 titles push the console’s hardware harder than others, and those are generally the ones more likely to run into trouble on any emulator, mobile or desktop.
Device Hardware
AetherSX2’s own recommendation is a Snapdragon 845-equivalent chip or better, with 4 large cores. A game that runs fine on that tier of hardware may struggle noticeably on a weaker phone.
Chosen Settings
The same game can perform very differently depending on renderer choice, resolution, and the CPU-related settings covered in our AetherSX2 best settings guide. A game that stutters at default settings might run acceptably once those are adjusted.
Emulator Build
AetherSX2’s official development has stopped. Which build or patch you’re running can itself affect how a specific game behaves.
Can You Trust Community Compatibility Lists?
Some exist, usually maintained by individual hobbyists rather than AetherSX2 itself. The more transparent ones are upfront about what they actually are, describing their own ratings as reflecting subjective playability based on hands-on testing, not technical benchmarks or guarantees.
That’s a reasonable way to treat any of these lists. They can point you toward what other users have experienced, but they’re not a substitute for testing on your own device, and a rating from someone else’s phone doesn’t guarantee the same result on yours.
How Should You Test a Game Yourself?
Load the game with AetherSX2’s default settings first, since that gives you a baseline before you start changing anything. If performance isn’t where you want it, adjust one setting at a time using our best settings guide, rather than changing several things at once.
That way, if something breaks, you’ll actually know which change caused it.

Conclusion
No list can tell you for certain whether a specific game will run well on your specific phone, but the variables above give you a real way to test and adjust rather than guess. Our AetherSX2 best settings guide covers the adjustments in more depth, and our AetherSX2 controller setup guide has you covered once a game is running the way you want.
