Hollow Knight on ARM (32-bit): Is there a way to play natively?
However, there are excellent academic papers and technical theses that analyze Hollow Knight as a case study for 2D game architecture, optimization, and aesthetic design. Why this is a good fit: If your
Depending on whether you are interested in the code architecture or the visual art style, here are the best papers to cite:
There is no legitimate 32-bit version of Hollow Knight, and one will never be released. The game’s design, engine, and modern development practices make 64-bit mandatory. If your system cannot run 64-bit executables, you will need to upgrade your hardware, install a 64-bit OS, or play on another platform.
Hollow Knight remains a masterpiece — but it is a masterpiece that looks firmly forward, not backward.
First, a quick technical primer. A 32-bit operating system can only address a maximum of 4 GB of RAM. While Hollow Knight is not a VRAM-hungry AAA monster, its later areas (like the Queen’s Gardens or the intricate particle effects of the Colosseum of Fools) benefit from memory headroom. When the game was initially released in 2017, 32-bit builds were still common. However, as Unity engine updates rolled out and the player base migrated to 64-bit systems, support for the older architecture faded.
Why does this matter? If you try to run the standard Steam version of Hollow Knight on a 32-bit machine, the OS will simply refuse to execute the code. You won’t get a crash or a stutter—you’ll get a hard "This app can’t run on your PC" error.

Let’s get the hard truth out of the way immediately: Team Cherry does not provide an official 32-bit executable for Hollow Knight.
When the game launched on PC (via Steam, GOG, and Humble Store), the developers built it exclusively for 64-bit architectures. This decision was made around 2017, a time when the vast majority of gaming PCs had moved to 64-bit processors and operating systems.
Why? Because 64-bit allows the game to access more than 4GB of RAM. Hollow Knight, while appearing "simple" due to its 2D hand-drawn art, loads massive interconnected zones into memory simultaneously. On a 32-bit system, the game would likely crash due to memory limits.
