ps2 emulators for android phones?

Not really no, pS2 emulator only started getting good on PC in the recent years. for phones you probably won't find anything super good for the 3D era of games (playstation, nintendo 64)

AetherSX2, but only if you can find the old version somewhere on the internet, because it was sabotaged not so long ago on play store

Yeah, I had the same doubt—wasn’t sure which one to trust on Google Play either. I ended up looking into aethersx2apk after a friend mentioned it. It brought back all the childhood memories—GTA, God of War, Tekken 5, even Shadow of the Colossus. Runs smooth on my phone and no console needed. Just make sure to get it from a trusted source, not some random clone.
