Late 1.2, days before 2637
AetherSX2 v1.2-2632 APK Download
This build exists on the site for one reason: it is the only thing that sits between v1.2-2637 and the rest of the archive. Released days earlier and near-identical, it is the control in an experiment, not a daily driver — and that narrow purpose is genuinely useful when a single game regressed across those few days.
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 v1.2-2632? Real-World Notes
v1.2-2632 was released only days before v1.2-2637 and is functionally very close to it — a handful of specific fixes apart. It exists in most archives because a small number of games regressed between the two builds, so having both available lets you A/B test.
In day-to-day use, if v1.2-2637 works well for your library then there is little reason to switch. If a particular game glitches on 2637 but was reported working slightly earlier, this is exactly the build to try.
As with all 1.2 builds, keep upscaling conservative and rely on native resolution — the graphics core here is a full generation behind the 1.5 line and reacts less predictably to aggressive settings.
What to Know Before Installing v1.2-2632
- The difference between this and 2637 is a handful of fixes. If you are not chasing a specific regression, you will not be able to tell them apart.
- It is the older of the two, so anything fixed in those few days is not fixed here — the comparison cuts both ways.
Recommended Settings for v1.2-2632
| Renderer | OpenGL |
|---|---|
| Resolution | Native (1x) only |
- Change exactly one thing at a time. This build is only worth installing as a comparison, and a comparison with two variables tells you nothing.
- Test the one game that sent you here, not your whole library. If it behaves the same as on 2637, the build is not your problem.
- Avoid aggressive upscaling entirely — the graphics core here is a full generation behind 1.5 and responds unpredictably to it.
Installing v1.2-2632
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: v1.2-2637 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 v1.2-2637.
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 v1.2-2632 Isn't Right for You
Skip this build if: Essentially everyone. Install v1.2-2637 instead unless you are specifically chasing a regression between these two builds.

Frequently Asked Questions
Why host two builds released days apart?
Because a small number of games behave differently across them, and no single build of an emulator this old is right for every title. Keeping both means a reader who hits a specific regression has somewhere to go. It is the same reason archives keep adjacent builds generally: the value is not in either file alone, it is in being able to compare them.
Which of the two should I install first?
v1.2-2637, without much hesitation. It is the later build and carries the fixes made in between. Come to 2632 only after 2637 has demonstrably failed you on a specific game — installing the older build first just means you find the same problems later.
Is there any reason to prefer 2632 for general use?
Honestly, no. If someone tells you the earlier build is broadly better, treat that as an unverified claim — the two are close enough that a general preference is far more likely to be placebo than a real difference. Its value is narrow and specific, and that is the only basis on which we would recommend it.
