Should You Use v1.5-4248? Real-World Notes
v1.5-4248 is the last AetherSX2 build ever released and the exact build the NetherSX2 patch targets. On its own, the Play Store variant of this release shipped with ads; the community answer is to apply the free xdelta patch, which removes them and adds ongoing compatibility fixes.
If you have a Snapdragon device with an Adreno GPU, this is the version to use — patched. The patch tool verifies the APK's checksum before applying, so a tampered file is rejected automatically.
Frontend users note: some launcher integrations (Daijisho, LaunchBox) reportedly broke in late builds. If launching from a frontend matters to you, test it, or use v1.5-3668 instead.
Installing This Build
- Uninstall any other AetherSX2 build first if you're downgrading — Android blocks installing an older version over a newer one.
- Enable "Install unknown apps" for your file manager, install the APK, and grant storage permission.
- Import your BIOS and games as in the full Android setup guide — the process is identical across versions.
Recommended: apply the NetherSX2 patch to this build before daily use — it removes the ads and adds community game fixes. Full walkthrough in our NetherSX2 patch guide.

Frequently Asked Questions
Is AetherSX2 v1.5-4248 still safe to install in 2026?
Yes, provided you verify the APK's SHA-256 checksum before installing and the file requests only storage permissions. v1.5-4248 is an archived build — it will never receive updates, so checksum verification is your main safety control.
What devices run AetherSX2 v1.5-4248 best?
The final build — patch it to NetherSX2 for the best experience. See the notes on this page for specifics.
Does AetherSX2 v1.5-4248 need a BIOS?
Yes — like every AetherSX2 build it requires a PS2 BIOS dumped from your own console. The same dump works across all versions; see our BIOS configuration guide.
Can I upgrade from v1.5-4248 to a newer build later?
Yes. Your BIOS, games, save states and memory cards live in storage folders that survive reinstalling a different build. Back up your data folder first as a precaution.
