Before diving into the emulator itself, it is essential to understand the technical barrier. Modern Android devices use 64-bit processors, which handle larger amounts of RAM and complex calculations necessary for PS2 emulation. The PS2’s Emotion Engine CPU is a 64-bit processor (MIPS architecture), but it often runs 32-bit instructions.
Never download an AetherSX2 APK unless it comes from a trusted archival source or the official community mirrors, and remember that none of the legitimate versions support 32-bit devices. Best Alternatives for 32-Bit Android Users
It is important to note that the original development of AetherSX2 was indefinitely suspended in early 2023 due to developer harassment.
First and foremost, there is no official 32-bit version of AetherSX2 . The developer, Tahlreth, made a definitive choice early in development to target 64-bit ARMv8 (AArch64) architectures exclusively.
