Mid-1.5, the mature stretch
AetherSX2 v1.5-3605 APK Download
Nobody picks 3605 as their first AetherSX2 build, and that is fine — it earns its place as the third thing you try. When 4248 and 3668 both misbehave on one specific game, this is the build that tells you whether a late-1.5 change is responsible or whether the problem is your device.
This archive APK stays available for people who need this exact build. The pages Google should index for version choice are the older versions hub, the current v1.5-4248 download, and the Mali-friendly v1.5-3668 build.

Should You Use v1.5-3605? Real-World Notes
v1.5-3605 comes from the mature stretch of the 1.5 line. It already includes most of the graphics-core fixes that built up through 2023, while sitting just before the changes some users blame for late-build quirks on specific phones.
Think of it as your troubleshooting build. If 3668 or 4248 misbehaves with a particular game on your device, builds this close together differ mainly in small per-game fixes, so dropping back one step is a quick, legitimate thing to test.
It runs on the same Android 8.0+ requirement as the rest of the line and uses the same BIOS, so switching to it costs you nothing but a reinstall.
What to Know Before Installing v1.5-3605
- Released in the same month as 3668, so the two are close relatives — expect small differences in specific games rather than a different overall experience.
- It is ad-free, like everything in the 1.5 line before the late builds.
Recommended Settings for v1.5-3605
| Renderer | Vulkan |
|---|---|
| Resolution | 1x native while you are diagnosing, then raise it |
- Use this build for A/B testing, not for tuning. Install it, load the exact game that failed on a newer build, and change nothing else — that is the only way the comparison tells you anything.
- Keep the newer build's settings in mind but re-enter them by hand rather than assuming they carried over.
- If the game behaves identically here, the problem is very unlikely to be the build, and your time is better spent in per-game settings or on the compatibility database.
Installing v1.5-3605
A standard single-file APK: enable "Install unknown apps" for your browser or file manager, tap the download, and approve the install.
Coming down from a newer release: v1.5-3668 or anything above it: means uninstalling that first, because Android refuses to install an older version over a newer one. Back up your memory cards before you uninstall. Those survive the move between builds; save states do not, so save inside the game rather than relying on a state you made on v1.5-3668.
The rest of setup is the same for every AetherSX2 release, so we publish it once rather than repeating it here: see the illustrated 12-step install and BIOS walkthrough, or go straight to the PS2 BIOS guide if that is the part you are stuck on. Once the app boots, apply our baseline graphics tuning before raising upscaling.
If v1.5-3605 Isn't Right for You
Skip this build if: Anyone installing their first AetherSX2. Start at 4248 or 3668 — come here only when you have a specific game misbehaving on both.

The build immediately after this one, and the better everyday choice — come back up to it once you have finished testing.

If dropping within the 1.5 line changes nothing, the top of the 1.4 line is a genuinely different graphics generation and a much bigger test.

Frequently Asked Questions
How much actually differs between v1.5-3605 and v1.5-3668?
Very little in broad terms. They are weeks apart in the same development line, so the difference is a set of specific per-game fixes rather than any change to how the emulator works. That is precisely what makes 3605 useful: because so little else changed, a game that behaves differently between the two points at a real, narrow cause rather than at general instability.
When is it worth dropping back to this build?
When one particular game is broken and everything else runs fine. A device-wide problem — everything stutters, nothing boots, the app crashes on launch — is almost never fixed by moving one build sideways, and your time is better spent on the renderer setting or the BIOS. A single misbehaving title is the case this build exists for.
Will my saves from a newer build work if I move down to 3605?
Memory card saves carry over — those are ordinary files in your storage and are not tied to a build. Save states are the risk: they capture the emulator's internal state and are effectively build-specific, so a state made on 4248 may not load here. Before switching, save inside the game to a memory card rather than relying on a state.
