In plain words

MAME-PSGS is a GLSL shader designed for MAME arcade emulation that enables custom color palette adjustments. The tool allows users to modify how games are displayed by adjusting colors through shader effects. It is intended for arcade emulation enthusiasts and retro gaming fans who want to customize the visual appearance of classic arcade games beyond their original output. The shader functionality distinguishes it as a technical solution for users seeking greater control over game presentation during emulation.

  • A Marble Madness-inspired WebGL game we built for Netlify2024 · 5-million-devs.netlify.com · ▲616

    Hello HN! We’re a small creative studio specializing in real-time 3D experiences. Netlify approached us to design and build an interactive experience to celebrate reaching 5 million developers. Inspired by the classic game Marble Madness, we created a gamified experience where users control a ball through playful, interactive levels. The goal was to blend marketing content with the look and feel of a game to engage users. The app is built with Three.js [1], using our custom render pipeline and shaders, and uses Rapier for physics simulation [2]. The 2D content is overlaid on the WebGL view…

  • I made a little digital circuit simulator that operates on PNGs2022 · github.com · ▲259

    This is a little toy project of mine that lets you simulate digital logic graphs. It was inspired by Minecraft's Redstone and the Piet esolang. It's got some serious drawbacks-- you write circuits as PNGs and simulate them with a Python interface. It's slow to run and slow to experiment with. And it is certainly difficult to use for people with any kind of color blindness. But despite that, I hope this can still be a fun toy!

  • A PSX/DOS style 3D game written in Rust with a custom software renderer2025 · totenarctanz.itch.io · ▲57

    So, after years of abandoning Rust after the hello world stage, I finally decided to do something substantial. It started with simple line rendering, but I liked how it was progressing so I figured I could make a reasonably complete PSX style renderer and a game with it. My only dependency is SDL2; I treat it as my "platform", so it handles windowing, input and audio. This means my Cargo.toml is as simple as: [dependencies.sdl2] version = "0.35" default-features = false features = ["mixer"] this pulls around 6-7 other dependencies. I am doing actual true color 3D rendering (with Z buffer,…
