Products that do what Development Journey on Game Decompilation Using AI does
Hey, ever wanted to fully understand or tweak a nostalgic game that you love? So, I’m documenting my journey on matching decompiling a retro game, step by step, using AI and self-made tools. Three chapters are done, and the fourth is in progress. Matching decompilation is a fun reverse engineering challenge that paves the way to learn more about a game and fully customize it. Let me know your thoughts about my posts and the VS Code extension that I'm developing, called Kappa! Have you ever heard of matching decompilation, by the way?

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.

I made a strategy game where you play the US or China through the AI race, 2026 to 2030, sixteen quarterly turns in the browser. One run takes about half an hour. At the start, the game seals two dice you never get to see. Inside: how hard alignment really is, and how fast takeoff compounds. You get eval reports, but only as ranges, and they flatter you most exactly when your systems are least aligned. At the end you get a debrief which shows what your evals said each quarter and also what was actually true. I lost every run I played myself so far. Every number in the game is source-backed…

Hi HN! Solo developer here. 10 days ago, I started building this after spending countless hours copying/pasting marketing sections and fighting to keep them consistent with our design system. I wondered: "What if AI could understand our design system and generate React components that actually match it?" Current progress (10 days in): - Can generate hero sections that follow your design tokens - Uses your actual component variants and styles - Works with Next.js, Tailwind, shadcn/ui It's very early days, but I'm excited to share it with other devs who: - Are tired of rebuilding…

Hi guys, I’m excited to share an update on ReproModel, an open-source toolbox designed to streamline the testing and reproduction of machine learning models. I, like many of you, have really struggled with benchmarking and comparing models, from missing code, to opaque experiment parameters slowing the process. I decided to take matters into my own hands, and created a mini-toolbox in my free time to streamline the process. The goal is to reduce the time and effort spent on replicating experiments, enabling researchers to focus on innovation rather than setup. Knowing this task is not an…

Hi, so i'm making a 2D game engine with its own IDE and interpreted programming language, all are written in C# It's open source, and I'm looking for contributors! The backend engine is MonoGame, the IDE is WinForms and the project is real, not just another AI-slop... Please check it out, i promise it's an unusual thing! Here's a YouTube video showing me using the engine for making a little cute game: https://youtu.be/h_AnUg4yJWs?si=MR3nQCVvOMDP3iqg Any feedback is welcome!

I started off with a simple goal: port the game Soldat to Typescript. I ended up not only with the game, but with a full system to train AI bots to play my own game, building a neural net to train new bot AIs from tens of thousands of simulated matches with different strategies. It also runs live all the time on my website and has a news dashboard and you can replay any game exactly. It all was a very fun way to dig into Fable's capabilities. The bill if I had done this with API billing? Nearly $2000.

This is an idea I’ve been kicking around for a long time, and I decided to finally code it up. In the same way that Scrabble decomposes words into letters, what if there was a game that decomposed letters into sub-shapes? There’s a lot of directions this could go, and I’m still exploring the possibility space. Enjoy. Suggestions welcome. It doesn’t have a real name yet.

Hello Hacker News! I am Bertrand from Pruna AI. With my associates, John, Rayan, and Stephan, we are fellow researchers in AI efficiency and reliability coming from TUM. We are building an optimization engine that combines compression methods (e.g. quantization, pruning, compilation, batching…) in the aim of saving compute power when running AI models. This optimization engine take one base model as input and returns a compressed model as output. It aims to help for two things: - Make various AI models faster and/or smaller for various hardware (because they can require significant…

Hi all, I'm sure some of the best engineers out here are having a hard time standing out nowadays. It's hard to evaluate and improve your skills, when AI is writing the code. Especially when a junior dev is sitting by your side and "accomplishing" 2x more than you. I didn't like this reality where the line between real talent and AI slop is blurring, so I decided to create a challenge, purely for the community, that is made to truly give a stage for talented devs to stand out in the age of AI. We encourage devs to bring their agents with them, because the challenge is built to not be…

Hi everyone! I'm one of the developers behind this project. I wrote it with my two brothers, Daniel and Ricardo. For years the three of us have been curious about how multiplayer games work, which is why we decided to work on this project. Our goal was to gain a deep understanding of how different players can share the same 3D space, which is why we wrote our own tiny game engine instead of using something like Unity. We wrote the engine using C++ and OpenGL, and we then compiled it to WebAssembly using Emscripten so that it would run effortlessly on web browsers. We are really excited about…

Hola HN! Long time lurker, sometimes commentor, first time poster here. I’ve been working alongside my two co-founders and a few colleagues on a project I’m excited (and a little nervous) to share with you all! Like many of us, I’ve lived a tortured existence with AI coding (is it vibes?) over the past few months - I think November was a big moment with this. But, one thing I’ve noticed after building orchestration layer after orchestration layer is that the thing I always came back to was “what the hell is Claude Code actually doing?” Perhaps it’s because of the time Claude Code got…

To learn OpenAI’s APIs a bit better (but mostly for fun), I made this image matching/prompting game. The idea is to generate a matching image using a prompt with limited input. You’ll have 3 tries. A new image and leaderboard is automatically reset daily. Let me know your thoughts! Please visit TwinPics.ai - Chris Sev

Hi HN! I'd love your feedback for this AI storytelling game. Remember when you used to read choose-your-own adventure books as a kid? We're trying to re-create that. The site lets you create adventures by seeding them with parameters that end up feeding LLMs: title, genre, writing style, etc. Once you've done that, you can play your book like a game: with custom chapters, illustrations, voice narration, choices, and dice rolls. We’re really into the idea of merging the open-ended generative AI with goal-directed story arcs that the game author can control. Everything is open source (links…

Hey HN, it's Vineeth from Plastic Labs (https://plasticlabs.ai) and we built this demo/game to showcase the latent capabilities of language models to simulate identities. We wrote more about what it is and how to use it on our blog (https://blog.plasticlabs.ai/blog/YouSim;-Explore-The-Multive...), but I'll try to quickly summarize. We took heavy inspiration from projects like WorldSim, WebSim, and Infinite Backrooms and prompted Claude Opus to act like a CLI interface that can simulate these identities while another instance will interact with the CLI. To…

I haven't seen anything like this so I decided to build it in a weekend. How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question. Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache…

I recently embarked on a creative experiment where I used ChatGPT to craft an elaborate steampunk story. Inspired by the rich narrative and intricate details, I decided to transform various parts of the story into demo tables, complete with text and images using https://tabulator.ai/. The goal was to explore how AI can aid in the creative process and provide indie game developers and storytellers with some ideas quickly.

I wanted to learn more about RAG implementations, so I built something to solve the constant digging through manuals whenever we play a game. It's fairly simplistic, but actually has worked pretty well for some of these conflicts. Everythings Open Source on GitHub if you're curious (or have ideas), and I'd love to hear feedback from fellow boardgamers!

Fully leaned into vibe coding this time around. Started on v0, at some point ejected into running locally (getting v0's exported folder to run locally was a challenge), then iterated with Cursor over the course of a few hours. Really neat how much can be accomplished just conversationally these days.

Hey HN, I built Bisecto (https://bisecto.com), a minimalist browser game with one simple mechanic, cutting (bisecting) a procedural 2D shape into two exact 50/50 halves with a single straight line. Confession: I got completely hooked watching those viral reels of people trying to cut fruits and vegetables into perfectly equal halves, and that was my inspiration for this game :D I've been writing code for 12+ years, but for this project I leaned heavily on LLMs to quickly spin up this game, I thought it's going to be quick, but it took me some time (around 2 weeks) to make the…

Coding agent management is all the rage right now, and many tools are being created to fill the gap. As a power user for all tools I've used since I've started my software engineering career, I've always taken the time to test multiple tools thoroughly before deciding on one, and an agentic manager was no different. I've tested many tools, but ultimately landed on Agent of Empires (AoE for short). Why ? Because it's fast, the development is active and it's feature complete, and easy to contribute to. So I did (contribute). In my day to day workflow for my job, I need the ability to start…

Hey HN, as a former data analyst, I’ve been tooling around trying to get agents to do my old job. The result is this system that gets you maybe 80% of the way there. I think this is a good data point for what the current frontier models are capable of and where they are still lacking (in this case — hypothesis generation and general data intuition). Some initial learnings: - Generating web app-based reports goes much better if there are explicit templates/pre-defined components for the model to use. - Claude can “heal” broken charts if you give it access to chart images and run a…

Hi I've created a text-based RPG game in which you can experience different adventures and play interesting characters while the AI acts as a real time DM/story teller. There are multiple ways to interact with AI: 1) Input free will move 2) Input default move (affects resources) 3) Post a question to DM Also one more cool feature is that you can create your own adventure via simple form. Add scenes, add characters and make it public so other players are able to test it. I also plan to have 'competetive' side where players will pay some small fee to creators in crypto depending on…
