24 alternatives to demake – one source project compiles to any retro game console ROM
This started life as a graphics tool for a specific problem: gen AI can make retro-styled sprites but can't follow exact hardware constraints of pixels and colors. While building this I liked the idea that I can fan-out to any retro videogame console or handheld's specifications. I then devised my own declarative language - Demotic - to express the game you want to build as concisely and naturally as possible without implementation detail. To work on different machines, you use relative units, like vw, vh, vmin, vmax. It has a web UI, CLI and NPM package. Still a work in progress.
Demake is a tool that compiles a single game project written in Demotic, a declarative language, into ROM files for any retro game console or handheld. It solves the problem of ensuring AI-generated sprites conform to… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

In the wake of all the Unity nonsense, just wanted to toss the Raverie engine into this mix :) We’re building off a previous engine that we worked on for DigiPen Institute of Technology called the Zero Engine with a similar component based design architecture to Unity. Our engine had a unique feature called Spaces: separate worlds/levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering…

21st.dev▲1,211I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!

RomM is a self-hosted app that allows you to manage your retro game files (ROMs) and play them in the browser. Think of it as Plex or Jellyfin for your ROM library: it automatically fetches metadata, artwork, and game information from online metadata sources to transform your folders into a browsable collection. You can play games directly in the browser for consoles like the N64, Game Boy Advance, Nintendo DS, and PlayStation 1, using the integrated web emulator (https://emulatorjs.org/). Members of the community have released integrations for Playnite (Windows), muOS…

I got DOOM running in KiCad by rendering it with PCB traces and footprints instead of pixels. Walls are rendered as PCB_TRACK traces, and entities (enemies, items, player) are actual component footprints - SOT-23 for small items, SOIC-8 for decorations, QFP-64 for enemies and the player. How I did it: Started by patching DOOM's source code to extract vector data directly from the engine. Instead of trying to render 64,000 pixels (which would be impossibly slow), I grab the geometry DOOM already calculates internally - the drawsegs[] array for walls and vissprites[] for entities. Added a…

I’ve been working on this for about a year through four major rewrites. Godogen is a pipeline that takes a text prompt, designs the architecture, generates 2D/3D assets, writes the GDScript, and tests it visually. The output is a complete, playable Godot 4 project. Getting LLMs to reliably generate functional games required solving three specific engineering bottlenecks: 1. The Training Data Scarcity: LLMs barely know GDScript. It has ~850 classes and a Python-like syntax that will happily let a model hallucinate Python idioms that fail to compile. To fix this, I built a custom…

Hey HN, Over the past ~1.5 years, I built an open-source FPGA retro emulation handheld that can play Game Boy, Game Boy Color, and Game Boy Advance cartridges. To my knowledge, there isn't an existing open-source FPGA emulator that can play physical cartridges like this. One of my main goals was to do all of the pieces myself, and be able to understand every component of it, so I designed my own PCB, wrote the firmware, wrote a Game Boy and Game Boy Advance emulator for the FPGA (using the Chisel HDL), and designed a 3D-printed case. I detailed the design and development process in the…

I tried to build AI game animation generator last year ( https://news.ycombinator.com/item?id=40395221), a lot of people were interested, but it failed, mainly because the technology was not good enough. 1 year passed, there were a lot of developments in video/image generation. I tried it again, I think it works super well now. Actually beyond my expectation. You can generate all kinds of game character animation sprites with only 1 image. 1, upload your image of your character 2, choose the action you want 3, generate! Support basic actions like Run, Jump, Punch and…

After 25 years of writing software, I was feeling nostalgic for the kinds of things that got me into programming in the first place: the old DOS demoscene. I spent a weekend seeing if I could recapture some of that INT 13H VGA magic using today's web tech, but with the old-school constraints of doing it from scratch. The result is this portfolio of ten classic effects running in a single HTML file. It's all vanilla JavaScript writing to a element, with no external libraries. It was a fun challenge to implement things like: * The color palette cycling and smooth fading in the Plasma demo. *…

Hey Hacker News! Launching gptengineer.app into beta today. It's like Claude Artifacts, but: - you can edit the code in your fav IDE (two-way github sync) - installs npm packages - automatically picks up build and runtime errors and fixes them - very fast, built with rust The full stack capabilities are built on supabase (prefer to not have to handle auth + user data at this point so this is owned by the user) The seed for this project was an open source experiment, posted about that previously here: https://news.ycombinator.com/item?id=36422730 Would love feedback if you give…

GitHub repo: https://github.com/ArcadeMakerSources/ArcadeMaker (first of all, i want to say that I made this project for fun and challenge. I always wanted to create my own language. This has no business goal or something.) So the project is a 2D game engine (MonoGame backend) inspired by GameMaker 8. It includes its own IDE (built with WinForms) and an interpreted programming language that I wrote myself. The language—definitely the biggest challenge in the project—is a simple dynamically typed language. When I started, I had zero knowledge of how to build something like…
