For years, developing games for the original PlayStation has meant one thing: working close to the hardware, dealing with low-level code, and building systems almost from scratch. It’s a process that demands both technical knowledge and a deep understanding of the console’s limitations, something that has kept PS1 homebrew relatively niche compared to modern development.
That’s why what’s happening now feels so significant.
A new tool is pushing the boundaries of what many thought possible: bringing a modern game engine workflow to one of the most constrained consoles of its generation. And if it delivers on its promise, it could mark one of the biggest leaps the PS1 homebrew scene has ever seen.
To understand the impact, it helps to look at how games are typically made today. Modern developers rarely start from scratch. Instead, they rely on powerful engines like Unity, Unreal Engine, or Godot. These tools handle a large portion of the heavy lifting, from rendering and physics to scene management and asset workflows, allowing developers to focus primarily on gameplay logic rather than low-level implementation.
In contrast, developing for retro consoles has traditionally been a very different challenge. Systems up to the sixth generation (including the original PlayStation) often require developers to work much closer to the hardware. While later consoles made use of languages like C, which helped standardize development to some extent, much of the work still involved understanding the system’s architecture in detail. Going further back, into fourth-generation consoles and earlier, things become even more complex, often requiring direct use of Assembly and a deep knowledge of individual chips.
This is precisely why what’s happening now feels so significant. After similar advances were seen in the Nintendo 64 homebrew scene (check out Pyrite64), many assumed that something comparable wouldn’t be possible on the PS1 due to its tighter technical constraints. But that assumption may no longer hold true. A developer known as Bandwith is pushing the boundaries of what’s possible with a new evolution of his existing tools. Known for his YouTube channel focused on retro game development and for previous PS1 projects, Bandwith had already introduced PSX Splash Edit, a tool that allowed developers to export Unity-built scenes to the PS1. That alone was already a remarkable achievement, and it was even used in projects like Sauna PSX.
Now, however, the concept has evolved much further.
With his new update, now called
PSX Splash 2.0, developers are no longer limited to exporting static or isolated scenes. Instead, they can build complete games directly within Unity and bring them to the original PlayStation. If fully realized, this could mark a major shift in how PS1 homebrew is approached. The tool offers a range of features that significantly expand creative possibilities.
Developers can
monitor memory usage in real time, including RAM, VRAM, and SPU RAM (a crucial aspect when working within the strict limitations of the hardware). It also supports camera movement, object animations, and scene transitions, making it possible to create more dynamic and cinematic experiences.
Character animation is another area where the tool shows promise. Developers can define skeletal structures and implement movement systems such as walking, jumping, or attacking. Interestingly, scripting is handled through Lua rather than C, with dedicated documentation designed to simplify implementation and lower the barrier of entry for newcomers.
Taken together, these features suggest a future where developing for the PS1 may become significantly more accessible without completely losing the technical depth that defines the platform. Tools like this could significantly reduce development time, allowing creators to prototype ideas in hours instead of weeks. More importantly, they lower the barrier of entry, making PS1 development accessible to a much wider audience, including developers already familiar with modern engines. Instead of starting from scratch, creators can now rely on workflows they already understand, and then adapt them to the constraints of the hardware.
The timing of this announcement also adds to the excitement. Bandwith has confirmed that a PS1 homebrew game jam will begin in just six days, potentially giving developers an immediate opportunity to experiment with these new tools and push them to their limits. More details about the event are expected soon.
Looking ahead, there are even more ambitious possibilities on the horizon. The developer has hinted at the potential for expanding this workflow to support Godot in the future, which would further broaden the ecosystem and attract an even wider range of creators.
While it’s still early days, this development could represent a turning point for the PS1 homebrew scene. One that bridges the gap between modern game development workflows and the unique challenges of retro hardware. And if it continues to evolve, it could redefine what’s possible on the original PlayStation.
