The last alpha before 1.0
AetherSX2 alpha-2230 APK Download
Two-two-three-zero is the last thing AetherSX2 shipped before calling itself 1.0, and the gap between them is days. That makes it a useful reference point rather than a useful emulator: it is the closest you can get to seeing what the 1.0 milestone actually consisted of.
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 alpha-2230? Real-World Notes
alpha-2230 is one of the last alpha builds AetherSX2 shipped, released days before v1.0-2233. In practical terms it is nearly identical to that first stable release — a snapshot of the emulator at the moment it graduated from testing.
Its main use today is archival. It is the reference point people cite when comparing how the emulator behaved just before 1.0 versus how a specific fix or regression affected the transition. Rarely useful as a daily emulator, occasionally useful for a hard-to-explain compatibility puzzle.
Install requirements are the same as any AetherSX2 build: Android 8.0+, a BIOS dumped from your own console, and reasonable expectations set to 2022-era mobile PS2 performance.
What to Know Before Installing alpha-2230
- It carries an alpha label, and that label was accurate at the time — this build was not positioned as finished software.
- Days separate it from v1.0-2233, so any difference you find between them is narrow and specific rather than general.
Recommended Settings for alpha-2230
| Renderer | Default |
|---|---|
| Resolution | Native (1x) |
- Install it alongside a clear question. As a general-purpose emulator it has no advantage over 2233; as a comparison against 2233 it is the only file that does the job.
- Expect alpha behaviour and do not report oddities as surprises — this build was explicitly not finished software.
- Keep a memory card save from a stable build if you want to test the same game across both, since save states will not transfer.
Installing alpha-2230
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: v1.0-2233 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 v1.0-2233.
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 alpha-2230 Isn't Right for You
Skip this build if: Anyone who wants to play something. v1.0-2233 is days newer, stable-labelled and functionally equivalent — there is no reason to choose the alpha for actual use.

Frequently Asked Questions
Is the final alpha meaningfully different from v1.0-2233?
Not in any way most people would notice. They are days apart, and the 1.0 designation marked a project milestone rather than a large technical change. If you are choosing one to use, use 2233. The alpha is interesting precisely because it is so close — it shows that the 1.0 launch was a decision about readiness, not a sudden leap in capability.
Why would anyone install an alpha build in 2026?
One legitimate reason: you have a compatibility puzzle that straddles the 1.0 boundary and you want to know which side of it a behaviour appeared on. That is a narrow case and it is genuinely the only one. For every other purpose — playing games, testing your phone, seeing what the emulator was like — a stable build serves better.
Does the alpha label mean it is unsafe?
Not unsafe, just unfinished. Alpha here means the developer had not declared it ready, so expect rough edges and missing polish. Safety is a separate question and the answer is the same as for every file on this site: verify the SHA-256 shown on this page before installing, and check the app requests only storage permission.
