No copy of the console image comes with any Android PS2 app, and we don’t host one, so you need a dump of your own before the steps below. For a fresh setup we recommend ARMSX2, the open-source app that publishes its APK on GitHub (2.8.4, released 17 October 2026).
Quick answer: copy the uncompressed dump from your own PS2 to phone storage, launch the app, pick import on the opening screen and pick the main 4MB file. That is the whole AetherSX2 BIOS step, and it works the same way in NetherSX2 and ARMSX2. Get the app first, then the file.
AetherSX2 Status: Discontinued, Not Coming Back
AetherSX2, built by a single developer known as Tahlreth on top of PCSX2 code, ended development on 4 January 2023 after what the developer called “neverending impersonating, complaints, demands, and now death threats.” Google Play removed the listing on 10 March 2024. An old install keeps working, yet it gets no fixes, and the official site is now a blank page. The AetherSX2 GitHub page is a notice with no APK, and copies on GitLab, Reddit links, a mod APK pack or an .io domain are not from the developer. Avoid them: re-signed builds are a common way to slip in adware, and a random link from an emu forum can save you a search but cost you the pain of a wiped phone.
Which App to Install Today
| App | State in 2026 | Where it comes from | Import step |
|---|---|---|---|
| ARMSX2 | Active, open source, also on iOS and Apple-silicon Mac | Official GitHub releases (Android 8.0+, 64-bit) | Opening screen, then Location in the menu drawer |
| NetherSX2 | Community patch of the last app builds (3668 classic, 4248 patched), latest dev build 2.2n from December 2025 | Trixarian NetherSX2-patch repo; unofficial | Same Import BIOS button as the original, plus Transfer Data |
| AetherSX2 | Frozen since 2023 (builds such as 3060 date from 2022) | No official source left | Import on the opening screen |
NetherSX2 is a modified build of closed-source code, so treat it as a grey area. ARMSX2 needs a 64-bit ARM phone; the team recommends 6 GB of RAM and a Vulkan-capable GPU.
Setup Guide: Import the Image Step by Step
- Copy all the BIOS files from the dump you made with our dumper guide, every part, to one folder on internal storage, for example Download/ps2. Unzip it first; the apps cannot read inside an archive.
- Open the app. On the opening screen choose the location or import option, then browse to that folder path.
- Pick the main 4MB file, about 4 MB or 4,194,304 bytes (the .rom0, or a single .bin from an older dumper). ARMSX2 checks every file it finds and skips anything it does not recognise.
- ARMSX2 accepts only a valid BIOS and shows the BIOS version beside each model name. Select the entry and confirm; only 1 entry is active at a time. Do the steps in that order. In ARMSX2, tap Use Selected and open the menu drawer later to change it or to boot the system menu with no disc.
Games come next: add a folder of ISO backups you ripped from discs you own. On a PC, use the official PCSX2 builds instead; the same dump works there too.
BIOS Issues: Missing Image or Failed Import
- Missing image error: you picked a folder holding only the .nvm or .rom1 parts, or a zip. Point the app at the main part, uncompressed, and the no image found message goes away. A dump is required; nothing else can fix it.
- Import failed from SD card or cloud: copy the files to internal storage and try again, since Android file access can expire.
- Loading hangs or the wrong menu appears: a large file from an unknown source may be damaged. Re-dump your PS2 and check the SHA1 against the Redump list.
- Lag in heavy titles such as God of War, Resident Evil or NFS: that is device speed, not the image. Lower the resolution, then change renderer.
BIOS Types by Market on a Phone
The best match is a dump from the machine that played your discs. An American (NTSC-U) unit suits USA releases, a Japan model suits imports, and a PAL unit from Europe (Europa in many menus) suits European ones. You can keep several on hand and pick one per game in ARMSX2. For the model codes and our region buttons, see the PS2 BIOS image hub.
FAQ
Is it legal? Copying the system code from hardware you own is the route the emulator teams document. Taking a stranger’s file is not, and you also need to own the games.
Do I still need it on ARMSX2? Yes. Every PlayStation 2 app on Android needs one to run PlayStation software; there is no open replacement. Keep a backup of the BIOS file outside your emulator so a reinstall costs nothing.
Other languages? Español: el emulador no trae la imagen de tu consola; descargar no basta, para importar abre la carpeta en el teléfono. Português: como baixar não resolve, o melhor é usar a imagem do seu aparelho e instalar o app oficial. Français: choisissez le fichier principal. Italiano (ITA): scegli l’immagine principale. Bahasa Indonesia: cara pasang file di ARMSX2 sama. The apps show menus in English, German and other languages, and search for juegos never changes the steps.
