Because Dolphin is an open-source project hosted on GitHub, its entire version history is preserved. If you absolutely require a 32-bit version, you have two primary routes: official legacy releases or community-maintained forks. Official Legacy Builds (Dolphin 4.0.2 and Older)
By 2014, less than 1% of Dolphin’s active user base was running 32-bit operating systems. Finding 32-Bit Dolphin Code on GitHub

The GameCube and Wii hardware use a PowerPC architecture with 32 general-purpose registers and 32 floating-point registers. Mapping these efficiently onto a 32-bit x86 CPU (which only has 8 general-purpose registers) created a massive "register pressure" bottleneck. Moving exclusively to 64-bit allowed Dolphin to utilize the expanded register set of modern CPUs, resulting in a 20% to 30% speed increase across the board. The GitHub Legacy
Because Dolphin is licensed under the GNU General Public License (GPL v2+), its source code is fully accessible on GitHub. This open-source nature allowed independent developers to fork the repository and maintain 32-bit compatibility long after the official team moved on.

When we think of the , the image that comes to mind is usually a high-performance powerhouse running on modern 64-bit systems, capable of upscaling The Legend of Zelda: Twilight Princess to 4K at 60 frames per second. However, for a significant period in the history of PC gaming, Dolphin 32 bits was the standard.
For many years, the Dolphin team officially supported 32-bit (x86) operating systems. As of modern development (2025-2026), official builds from the main Dolphin Emulator GitHub repository are , requiring Windows 10/11 or modern Linux/Android 64-bit architectures.

One notable example is the "Ishiiruka" fork. While primarily focused on delivering enhanced visuals and performance options that the official build avoids, Ishiiruka maintained legacy support longer than the official build, becoming a haven for users with slightly older hardware.
So, if you are determined to use a 32-bit version of Dolphin, what are your options? It's not as simple as downloading an installer, but there are a few paths you can take.
