Dolphin Emulator does not support 32-bit Android. Modern versions require a 64-bit (ARMv8 AArch64) operating system to function. If your device is strictly 32-bit, the official app will not run. ⚠️ The 32-Bit Reality
“Performance improvements in 64-bit mode are dramatic. We cannot recommend anyone use the 32-bit build for any purpose other than testing legacy devices.”

The 32-bit builds have been archived. You will not find them on the official Dolphin website (dolphin-emu.org). You must search third-party repositories like GitHub (old release tags), APKMirror (historical builds), or various emulation forums. Dolphin Emulator does not support 32-bit Android
