Check the "Commits" tab. A trustworthy repository will have clear logs explaining what changes were made to enable 32-bit functionality, rather than just hosting a mysterious, pre-compiled .exe or .apk file.
This 32-bit foundation was one of Dolphin's oldest and most defining features, a technical baseline that enabled its early development and success. dolphin 32 bits github

When searching GitHub for these projects, look for repositories tagged with dolphin-emu , 32bit , or x86 . But – dependencies, libraries, and APIs have moved on
Missing modern SSE and AVX instruction sets slowed down floating-point math calculations.
Here’s the breakdown of why official support ended and how you can still find 32-bit versions today. The "Obituary" for 32-Bit Support
The GameCube and Wii use a 64-bit PowerPC architecture. Emulating a 64-bit CPU instruction set on a 32-bit host processor requires complex workarounds and heavy instruction translation. When Dolphin runs on a 64-bit (x86-64) CPU, it can map the emulated registers directly to the hardware registers, resulting in a massive, immediate performance boost. 2. The Memory Ceiling
