TL;DR
A developer is building a first-person shooter inspired by early 90s graphics, using strict limitations like 256 colors and 320×240 resolution. The project aims to recreate the look and feel of classic VGA-era games with modern development tools.
A developer has revealed a side project, Catlantean 3D, which aims to create a first-person shooter with graphics mimicking 1990s VGA-era limitations, using modern tools for development. The project emphasizes strict constraints such as 256-color palettes, 320×240 resolution, and hand-crafted assets, to evoke the look and feel of early PC games.
Catlantean 3D is a self-described attempt to reproduce the visual style of early 90s VGA graphics, specifically Mode 13h and VGA Mode-X, within a modern development environment. The developer has set constraints including a 256-color palette, hand-drawn and procedurally generated sprites, and a fixed resolution of 320×240. The project is built from scratch, with all assets created manually, including sound and rendering, and uses a platform abstraction layer to simulate limited hardware capabilities.
The developer, known as Catlantean on Hacker News, has detailed the technical limitations imposed, such as no shaders, fixed-point logic for deterministic behavior, and deliberate color choices to evoke the aesthetic of classic titles like Doom and Duke Nukem. The game is intended to be a complete, playable experience, not just a tech demo, with a focus on authenticity and deliberate artistic choices.
Why Retro Graphics Techniques Matter Today
This project highlights how technical limitations can influence artistic design, producing visuals with a distinct clarity and style that modern high-fidelity graphics often lack. It demonstrates that constraints like a limited palette and resolution can foster creativity and deliberate aesthetic choices, offering a different approach to game design that appeals to nostalgia and design purity. For developers and players alike, it underscores the value of understanding and experimenting with foundational graphics techniques, especially as modern hardware and software often obscure these fundamentals.

Historical and Technical Roots of VGA Graphics
During the early 1990s, VGA graphics modes like Mode 13h (320×200, 256 colors) defined the visual identity of PC games. These modes used simple linear frame buffers with palette-based color indexing, which limited the number of colors but made rendering straightforward. Classic titles such as Doom and Duke Nukem utilized these constraints effectively, resulting in crisp, recognizable visuals. Modern game development often bypasses these limitations, favoring millions of colors and complex shaders, but there’s a resurgence of interest in retro techniques for their aesthetic and artistic value. The developer’s approach aims to blend this nostalgia with contemporary programming practices.
“Restriction forces deliberate choices, and deliberate choices tend to look good.”

“I’m going for something closer to VGA Mode-X, 320×240, to avoid non-square pixels and for aesthetic reasons.”

Unresolved Technical Challenges and Artistic Choices
It remains unclear how the developer plans to implement advanced effects like dynamic lighting and shading within the strict palette limitations. The methods for achieving visual depth and realism, such as dithering or palette manipulation, are still in development. Additionally, the final visual quality and performance on various hardware are yet to be tested in a complete build.

Key Questions
Why recreate graphics from the early 90s?
The developer aims to explore how constraints shape artistic design and to evoke nostalgia for classic PC games, offering a fresh perspective on game aesthetics.
How will modern tools be used within these constraints?
The developer uses a modern compiler and platform abstraction layer to manage rendering, sound, and input, while deliberately limiting features to emulate vintage hardware.
Will the game support modern hardware?
Yes, the project is built to run on contemporary PCs, with the constraints serving as a stylistic choice rather than a technical limitation.
Are there plans to add effects like lighting or shading?
The developer is experimenting with techniques to simulate lighting effects within palette constraints but has not yet finalized these features.
Is this project just a tech demo or a full game?
The goal is to develop a complete, polished game that is fun to play, not merely a demonstration of technical constraints.
