Deltarune, developed by Toby Fox and released originally for 64-bit Windows, macOS, and Nintendo Switch, is a role-playing game built in GameMaker Studio 2. While the official builds target 64-bit architectures, a 32-bit edition would allow the game to run on legacy hardware (e.g., Pentium 4-era PCs, Windows XP/Vista/7 32-bit OS, netbooks with Atom CPUs) and certain embedded or retro-focused platforms.
This write-up outlines the feasibility, modifications, performance considerations, and packaging for a hypothetical 32-bit port.
Deltarune does not currently support 32-bit Windows as of its latest public builds. Players still on 32-bit OSes should either find an older 32-bit compatible version (Chapter 1+2 only, no guarantee for future chapters) or upgrade their operating system to 64-bit. For a seamless experience with upcoming chapters (3 & 4), a 64-bit environment is essential.

on 32-Bit Systems: Current Status and Workarounds If you’re trying to jump into the Dark World on an older machine, you’ve likely run into a frustrating "Not a valid Win32 application" error. Currently,
Deltarune Chapters 1 & 2 do not officially support 32-bit operating systems.
The game is built using GameMaker, and modern exports generally target 64-bit architecture to maintain compatibility with updated libraries and Steam's requirements. Here is a breakdown of the current situation and what you can do. The Official Compatibility Gap runs flawlessly on almost any toaster, is more resource-intensive and technically demanding. Official Requirement: official Deltarune website Steam Store page 64-bit processor and operating system as a minimum requirement. The Problem: Trying to launch the 64-bit
on a 32-bit system will result in an immediate crash or a "system incompatibility" message because the hardware cannot process the instructions. Potential Community Workarounds
Since there is no official 32-bit build, the community has looked for ways to bypass this. Use caution with third-party files to avoid malware. Virtual Machines:
Some users attempt to run a 64-bit environment inside a 32-bit host. However, this is rarely successful as the physical hardware usually lacks the necessary virtualization features to emulate a 64-bit OS efficiently. Unofficial Ports:
There are community-made "legacy" wrappers or ports discussed on platforms like Reddit's r/Deltarune . These often involve replacing certain
files from older GameMaker games, though stability is never guaranteed. The "Undertale" Method: Some players have experimented with using the runner file ( runner.exe (which is 32-bit compatible) and renaming it to match the
data files. This has mixed success and often leads to broken sprites or crashes during cutscenes. Recommendation: Upgrading or Alternatives If your hardware supports it, the most reliable fix is to reinstall a 64-bit version of Windows.
Most processors made in the last 15 years are 64-bit capable, even if they are currently running a 32-bit OS. Alternatively, you can play on other platforms that handle the architecture for you: Nintendo Switch: Available for free on the Nintendo eShop PlayStation 4/5: Available on the PlayStation Store is 64-bit compatible?
Running on a 32-bit system is tricky because the game officially requires a 64-bit processor and operating system. While Undertale was a 32-bit program, Deltarune (Chapters 1 and 2) was built using newer versions of GameMaker that default to 64-bit architecture. Potential 32-bit Solutions
If you are restricted to a 32-bit environment, here are your best options for a "solid" experience:
Download from itch.io: Some users have reported that the version of Deltarune available on itch.io may run on 32-bit systems where the Steam version fails to even download.
Legacy Chapter 1: Early standalone versions of Chapter 1 were more compatible with older 32-bit systems. However, these are harder to find officially now that Chapters 1 & 2 are bundled.
Linux/Chromebook Workarounds: If you are on a Chromebook or Linux, you can enable 32-bit architecture for Wine to run the Windows installer, though this requires technical setup via the terminal.
Unofficial Android Ports: There are fan-made Android ports specifically optimized for 32-bit ARM devices, though these are not official releases and may have bugs. ⚠️ Important Compatibility Notes
Volatility: Official 32-bit builds were discontinued because they were "wildly volatile" and suffered from severe saving issues.
Steam "Win7 Fix": On Steam, you can try the "attempts to win7 fix" under the Betas tab in game properties, which might help with older system compatibility.
Hardware Limits: Even if the game launches, you will still need at least 2GB of RAM and a DirectX 12 compatible graphics card for smooth performance. If you'd like to try one of these, I can give you: Step-by-step instructions for the itch.io method. The specific terminal commands for a Chromebook setup.

Official support for 32-bit versions of Deltarune has effectively ended. While the initial Chapter 1 demo was compatible with 32-bit systems, more recent updates (including Chapter 2 and beyond) officially require a 64-bit processor and operating system. Current Compatibility & Requirements
The latest versions of the game, available on platforms like Steam and Itch.io, list the following minimum specifications: Operating System: Windows 10 or higher, 64-bit. Processor: 64-bit processor and operating system required. Memory: 2 GB RAM (4 GB recommended). Storage: 1 GB available space. Why was 32-bit support dropped?
Stability: Developers found that 32-bit builds were "wildly volatile," particularly causing severe issues with saving game progress.
Engine Evolution: Modern versions of GameMaker (the engine used for Deltarune) have transitioned to 64-bit as the default standard, making older 32-bit extensions and runners increasingly difficult to maintain. Potential Workarounds
If you are currently on a 32-bit system, your options for playing Deltarune are limited:
Deltarune 32-Bit: Compatibility, Myths, and Solutions For many players with older hardware, the jump from Undertale to Deltarune brought an unexpected technical hurdle: system architecture. While Undertale is a 32-bit program that runs on almost any machine, Deltarune Chapters 1 & 2 officially require a 64-bit processor and operating system.
This guide breaks down why the 32-bit version was discontinued, how to check your system, and what options you have if you're stuck on an older 32-bit machine. 1. Why Isn't There an Official Deltarune 32-Bit Version?
Early versions of Deltarune Chapter 1 initially had 32-bit builds, but as the game expanded into Chapter 2 and beyond, the developers transitioned exclusively to 64-bit.
Stability & Saving Issues: 32-bit builds were reportedly "wildly volatile," leading to severe issues with saving game progress.
GameMaker Studio 2: The engine used to build the game, GameMaker Studio 2, updated its runners. While older versions produced 32-bit executables, newer implementations (especially those handling web sockets and modern features) are optimized for 64-bit systems.
Performance: A 64-bit architecture allows the game to handle larger amounts of memory more efficiently, which is necessary as Toby Fox’s projects become more complex. 2. System Requirements at a Glance
To run the latest version of Deltarune (Chapters 1-2 and the upcoming Chapters 3-4), your PC typically needs to meet these specs: Minimum Requirement OS Windows 10 or higher (64-bit Required) Memory 2 GB RAM (4 GB Recommended) Graphics 128 MB VRAM (DirectX 12 compatible) Storage 1 GB available space 3. How to Check if Your PC is 32-bit or 64-bit

It's worth noting that the 32-bit version of Deltarune is no longer officially supported, and players are recommended to use the 64-bit version for better performance and compatibility.
(and subsequent chapters like 3 & 4 released in June 2025) are optimized for 64-bit architectures Performance:
64-bit systems can handle larger memory addresses, which helps with the game's increasingly complex assets and sound files. Popular modding tools like the UndertaleModTool
have historically struggled with 32-bit volatility, leading some developers to cease official 32-bit support for their editors. Community & Modding Efforts
Because there is no official 32-bit support from Toby Fox, the community has taken matters into its own hands: Fan Ports:
Enthusiasts have experimented with recreating the battle system in alternative engines like Construct 3 You need a specialized patch created by the community
to build custom fights (e.g., the "Mad Spam Spam" boss) that could theoretically run on different specs. Technical Workarounds: Modders often use tools like to extract and modify the
files, attempting to bridge compatibility gaps or create custom content that mimics the original experience. Unofficial Versions: Discussions on platforms like Reddit's CrackSupport
often mention unofficial 32-bit versions, though these are typically community-modified and carry risks compared to official releases. The "Retro" Aesthetic

Additional Resources
While shares the retro aesthetic of its predecessor Undertale, its relationship with 32-bit technology is primarily a point of technical limitation rather than just an artistic choice. Technical Compatibility (64-bit Requirement)
Modern versions of Deltarune (Chapters 1–4) officially require a 64-bit processor and operating system. This is a departure from Undertale, which remains a 32-bit program.
Official Requirements: The official Steam page and PCGamingWiki specify that Windows 10 (64-bit) or higher is required for the game to run.
Volatile 32-bit Builds: While early versions of the game (specifically Chapter 1) were once 32-bit compatible, subsequent updates for Chapters 1 and 2 proved "wildly volatile" on 32-bit systems, often leading to severe saving issues. As a result, official 32-bit builds are no longer provided.
Platform Support: As of January 1, 2026, Steam Support stopped supporting 32-bit versions of Windows entirely, further limiting accessibility for older hardware. 32-bit Aesthetic Influence
Outside of system architecture, "32-bit" is often used by fans to describe the game's evolved visual style. While Undertale is frequently associated with an 8-bit or 16-bit NES/SNES vibe, Deltarune features more sophisticated pixel art.
Visual Fidelity: Players often compare Deltarune's graphics to the 32-bit era (such as the PlayStation 1 or Sega Saturn) due to its more expressive animations by Temmie Chang, increased color depth, and complex parallax scrolling.
Enhanced Mechanics: The battle system includes rotation and scaling effects that would have been difficult to achieve on older 8-bit or 16-bit hardware, leaning more into the capabilities of 32-bit engines.

Since there is no official retail version of Deltarune labeled "32-bit" (the official PC version is 64-bit only), I have developed this guide based on the most common interpretation of your request: How to run Deltarune on a 32-bit system or via 32-bit architecture.
This guide covers the problem, the solution (using a specific fan-made wrapper), and a full setup walkthrough.
Before diving into patches and workarounds, it’s crucial to understand why the keyword “Deltarune 32-bit” exists in the first place.
Modern computers (post-2010) primarily run 64-bit operating systems (Windows, Linux, macOS). A 64-bit OS can handle more than 4GB of RAM and runs modern applications efficiently. However, millions of legacy machines—netbooks from 2007, industrial thin clients, old school laptops, or even dedicated retro-gaming PCs—run 32-bit (x86) architectures.
The problem: Deltarune, as distributed officially via Steam and Itch.io, is a 64-bit native application. Toby Fox’s development team (using GameMaker Studio 2) compiles the game for 64-bit processors by default. If you download the game on a 32-bit Windows 7 or 32-bit Linux distribution, you will receive an immediate error: "This app can't run on your PC."
To understand the lack of a native Deltarune 32-bit build, you must look at the engine. YoYo Games (now owned by Opera) officially dropped 32-bit desktop exports from GameMaker Studio 2 in version 2022. The reason:
Toby Fox would have to maintain a separate, legacy codebase—a nightmare when Chapter 3, 4, and 5 are in active development.
✅ Yes if:
❌ No if:
This is a common issue with older GameMaker wrappers on 32-bit systems related to keyboard input mapping.
While Deltarune officially requires a 64-bit operating system to run properly, many players with older hardware are still looking for ways to play the game on 32-bit machines. This search for "Deltarune 32 bit" often stems from the fact that its predecessor, Undertale, was a 32-bit application, and some early demos of Deltarune were reported to work on older systems. Official Compatibility and Engine Requirements
Modern versions of Deltarune, including Chapters 1 through 4, are built using a 64-bit runner in GameMaker Studio 2. This architecture is standard for newer releases to ensure stability and performance, particularly as the game’s complexity has grown since its 2018 debut.
Official Minimum Requirements: Windows 10 (64-bit) or higher.
The 32-Bit Problem: 32-bit builds are not officially provided because they were found to be "wildly volatile," often leading to severe saving issues and crashes during testing of Chapters 1 and 2.
Steam vs. Itch.io: The Steam version strictly enforces the 64-bit requirement and may block downloads on 32-bit systems. However, some users have reported that the Itch.io version may launch on certain 32-bit setups, though it is not officially supported and may be unstable. Troubleshooting and Workarounds
